K, let's say what I said bout the temp shocking the pump isn't true, the fact of the matter is...it IS bad for ur fuel pump to fill ur tank when its below half a tank or close to empty, and that is a fact. Most Americans don't keep their car for longer than couple years, so usually they don't have to change it, but a lot of used cars, and trucks especially, end up w/ a new fuel pump before its' life expectancy is up. The end. Take it or leave it. U want to fill up ur tank at almost empty or 1/4, be my guest...if ur lucky, ur pump will survive it...if not, eh what's $1000 for a new fuel pump installation to someone as smart as u.
Again as someone mentioned if this is true then the forums would be full of My fuel pump went out on my used "X"
A lot of folks are keeping cars longer and driving them further.
Running it dry, or so low cavitation occurs or not changing your fuel filter would all damage the fuel pump over time.
As mentioned letting or consistently operating with low fuel levels will lead to condensation, this water will also damage the fuel pump.
bottom line is nothing lasts forever.
Will operating it at a half tank or lower in of it's self damage the pump no, it's made to operate all the way to empty and in a wide range of temps.

You're contradicting yourself. You're stating what driving on low fuel will cause to happen to the system which ends up damaging the fuel pump, and yet you're saying driving on low fuel won't damage the pump...
And no, its not made to work forever, but you're lowering its life expectency. Of course running on low won't cause direct damage, but it will cause a chain of events that will damage it...
Low, what is low? a 1/4 tank is not the same as running it with the fuel light on. Continued running with the fuel light on could lead to cavitation which will damage the pump.
No mater the temp of the fuel.
No contradiction you just need clarification like I do.
so I have to ask again, can you show us something that backs up your Fact like I have or are you going to try to redirect my attention to something else?
While the MC fuel tank application may run somewhat warmer than a comparable car application, there's still the commonality of the same fuel and Reid Vapor Point to contend with. You can't have the MC run on vapors, it's still got to have liquid fuel under pressure at the injectors. Essentially, the fuel "may" be a little warmer, but it's still got to be delivered by the fuel pump and that means temperatures within the system and fuel working limits.
I'd bet that the failures of the fuel pumps in the Nomads are due to fuel slosh and picking up air into the pump at low fuel levels ... which promotes cavitation and damage to the pump. Another factor may be that the alternator output isn't as "clean" as it is in a car electrical system, which can stress the fuel pump motor; I've seen a lot of what I would consider to be marginal wiring and ground connections in many bikes, too. The saving grace is that as long as that litre and a half motor is still running, it's got more HP on tap than the bike needs to maintain road cruising speeds ... even if it's not running well. IIRC, even BMW has had a reputation for short life of the fuel pumps in the K series bikes ....
Mac, I am green with envy over that little alfa you found ... one of the best of the series. Seems like everybody I stumble across who has one sitting titsup out behind a barn or stashed away under a pile of dung in a garage thinks it's a fabulous prize that only needs a little work to bring it up to pristine glory and collectable dollar value. Many have long forgotten why they parked the car out of sight to begin with, which usually was being on the short end of cost/value ratio when the car quit running. For most of them, if they gave me the car, delivered it to my shop with a suitcase full of cash, I'd still be trying to get out from under the cost of putting it on the road.
I thought I had seen the vlast of D jet in the GM C series that used it for 8 cyls, 6 clys and 4, all on the same engine. I was wrong
Kawii used it on all the 1500's and 1600's Nomads, and perhaps all the Vulcan line. I was a little stunned to see it again. I got out during LH Injection due to burn out.
OT: I was more stunned to see Lucas Brake drums on Ford Escort 1990's vintage. Those were the very same as used on MGA, and the last MGA came out new in 1959. What's with that anyway?
The Nomad hold apx 5.2 gallons, and the tank sits right over the engine. Last time I checked heat goes up and a Nomad makes enough heat that I no longer have leg hairs below the knee on the inside of my legs
I think of shock as dipping steel bright orange hot in day light, into oil at air temp. That's a shock.
The water thing I am well aware of I have seen lots of 1890's plumbing in old New England homes, with a hot and cold faucet and no mixer. Made it hard as a child to get a just right temp for most anything.
Again in the 3 years of tee pee living. We would boil 1 gallon and add it to a canvass bag I made with a shower head and valve. Then we would add icey brook water to suit apx 3 to 4 gallons.
That Alfa is long gone. In fact I thought you owned it now That car sure could turn a corner.

Oh, man ... you missed out on all the fun to be had with CIS and the seeping injector nozzles or intermittent fuel pressure check valves.

The Escort was built as a "world car", capable of meeting many countries roadworthy specs with a single build line. I have no doubt that the Brits were keeping a whole crew off the dole by giving them make-work jobs; there were probably 10 times more hours per part in their manufacture than were needed. Tea time apparently took precedence over productivity; now they don't mess around. They just send the workers home on permanent furlough for the dole.
Ah, MGA's actually were produced through 1961. Another one of those little oddities I picked up back in the late 1960's was a 1961 1600 MGA Coupe (for $600!). If only I'd bothered to research that car before parting with it ... it was one of the last 14 built. Slightly rare, although at the time, not especially collectable or desirable. Today that might be a different story, although I do remember well the continuing encounters with the Prince of Darkness and those self unadjusting carburetors which took a top up of ATF every few days. At least the heater worked enough to clear the windshield and deliver a promise of heat to be forthcoming to the feet at the same time. It was only slightly less effective than a VW Bug's heater, so that wasn't too bad in that much smaller passenger compartment.

Of a real thermal nature, strong enough to rearrange molecules.

In our summer days, even a solar water shower can get into scalding temps and require cold water to balance it out. I've got a 5 gallon black container we use now to heat water for camping ... it'll do all the domestic supply and the dishes in an evening. We fill a sunshower from it as we like to take longer showers than the standard waterbag holds.

Damn, I went out back to check and be sure it hadn't morphed into the rest of the pile. Sure enough, nothing that nice out there.
No I don't have any links to show you, sorry. Maybe I explained it wrong, but not gonna try again. So it doesn't matter. You know what you know, and I know what I know.
Sun, CIS came before LH. My 85' Volvo day to day driver wagon has a B21 FT engine with CIS, and IMO it is the best Bosche Injection there ever has been.
LH is the one with the platinum wore in the throttle body. When these were new owners would wipe a finger on the wire thinking it was a stuck pine needle! Bad move
My error I thought it was 59.... 61 must be it. I like SU type 4 carbs and still have tools to work on the, but I really don't know why........ You had a heater?????? I recall adding metal fauctes and plumbing to a few A's that had no heaters from the factory.
The best part of the A's was that when they were made for the USA, left side drive the throttle linkage came across the inside of the fire wall/tranny tunnel and a passanger could step on the linkage to go faster. I turned a few fella's gray stepping on that, forcing them to steer more!
My wife is always trying to rearrange my molicules
Yeah the garden shower bag gets a tad too hot here in NH too in season.
It might be a good thing that canary yellow with a white rag top isn't in your collection. The colors were kinda girly if you ask me.
wicked, Sun has been bustin' knuckels for a living a rather long time, and probably like me owns enough tooling to have bought a house.
Tools like Snap On don't grow on trees, and in time one does tend to learn a few things.
The industry for techs covers a vast list of How To's.
We do wiring, AC and Dc current. We do carpent laying, wood working, like in converstion vans, reupholstery, as I am now doing on my own van from 86' which is a nice van, but the cloth went over the board. We do hydralics systems , machine work, fix what designs engineers got wrong.
We do engine rebuilds, tune ups, and diagnostics in our heads. Being a vehical tech, covers a lot of other occupations in one machine that brings many occupations into one item.
We weld, braze, as well, and can deal in glass work and paint when we must.
I get a good bit of my toys straight off a junk yard heap of metal.
This is a scrap yard special of mine. Came right off a heap of rust ed out junk in 1999.
So, what I'm hearing is you dreamt this up in your sleep.
How do you "know" this? Because your ID told you?
I can back up what I know.
You can't back up your theory.
It doesn't matter? O.k. if you say so.

Wicked, you obviously haven't learned a lesson I learned a long time ago; there's a time to keep your mouth shut and just listen. There is no better teacher than time and experience.
I've been fixin' cars for a long time now, yet I learn from Sunspirit's posts. Not too proud to admit it either.
I will say the auto forum certainly has been entertaining lately
Well I've learned this from men who have been working on cars for 40+ years, and what they told me, which like I said, maybe I didn't explain right, made sense to me and rest of people. I didn't ask for proof bc they have life time experience, so I don't have one to show u. And don't tell me that I need to shup up. The forum is for someone to ask someone else's opinion, it is clearly not the best resource for information at times. There is no need trying to prove me so hard. If I'm wrong, then so be it, its for the person who posted the question to decide whose advice he should take.
