Elec. Pump -Part two

[Brosky]

Excellent thought process Frank!! After all of the collapsed PCV and fuel hoses that I've seen over the years, I should have known to ask about those.

I'll bet that Dale's lines to the carbs are new, but what about those lines at the very rear, coming from the tank?

 

[DNK]

...The electric pump is NOT new and I do not
think it is working properly...

Dale- that pump if it is the one I gave you is brand new. I never ran any gas thru it at all. In fact it was mounted and never hooked up to a fuel line or an electrical source.

I agree with most ,the pump needs to be below the tank and is better as a pusher and not a sucker.

Thanks Don !!

Thanks-- great input to know.
But where should I move it to?

Hoses? Yes, every hose is brand spanking new-front and rear.
The steel line running thru the frame is NOT new but I flushed
it with gasoline and blew an entire can of carb cleaner thru it.
I tested it under pressure of 5 gallons in the tank.
Gasoline gushed out, so I'm real sure no clogs.

Plus I took the carbs off and cleaned the bowls. etc.

The car ran great with everything new and then quite
suddenly when the better than new, mechanical pump quit
pumping gasoline when Ian was driving in the hood.

About 110 miles total on the replacement fuel delivery system.
I'm still working on the first ten gallons of high test fuel.
So I doubt ethanol is the culprit but you never know.

I'll keep at it and report back in a part three.

thanks everyone for the input.

Hi Dale. Do you have a flexible hose between the tank and the steel fuel line? Do you have another, between the fuel line and the fuel pump? Were they replaced when you re-built the fuel system? I am asking because the symptoms you have described could be caused by a hose that has walls that are collapsing. I can't remember. Is your TR6 gas tank vented? I remember years ago when I was a high school kid cutting lawns in the summer. I had an old mower that I picked up and rebuilt. One time I couldn't get it started no matter what I did and just about wore myself out. I didn't realize that my dad was watching all of this from behind a tree. Finally he appeared and told me to unscrew the gas cap and try again. It started on the first pull. The vent hole in the cap had been plugged with dirt and fuel could not flow to the carbs. This is an over simplification, but it's worth checking.

good luck

Similar thoughts I had last night. Open the gas cap and drive it around a bit to see what happens (as long as the tank isn't so full that fuel sloshes out...

 

[Tinster]

Thanks Mickey!

Yes the tank is vented and yes I popped open the tank cap
as one of my very first diagnostic procedures. It made
no difference. I even removed the vent hose to be sure.

But it's nice to know my Rookie thought process is the
same as you Triumph Expert Knowledge guys.

We'll eventually settle this out!

Dale
I has a 1963 volvo and put an electric fuel pump on it and had a simular problem, the car would run fine and then die of no gas, I finally figured out that a piece of trash in the gas tank would get sucked to the outlet pipe in the tank and basically the fuel pump would hold it there and block the flow of gas, if I sat on the side of the road long enough the trash would come loose, pump would pump gas and on I went, someone suggusted to me I had trash in the tank, I pulled the sending unit out and looked in the tank and they were right. could you still have some trash in the tank? I know its a pain but you might have to pull the tank again and clean it out, I might try a wet dry vacuum cleaner to try to clean it out, but thats after you drain all the gas, not sure how dangerous that would be but I would definately have the vac a good ways away from anything

It wouldn't be dangerous if gasoline fumes weren't explosive and vacuum cleaner motors didn't make sparks.

Other than that Dale, you could make your garage bigger by trying it. The fuel system would be the least of your worries after that.

But seriously Hondo, there is a good probability that what you say could be true. Intermittent problems such as these always have some weird thing that isn't readily obvious or obtrusive, but just big enough at the right time to cause a problem.

 

[Tinster]

Hondo-

I gave that some thought as well.

I bounced the heck out the rear end, while the car
was at idle, and no additional fuel flow occurred.

My tank was VERY clean when I installed it.

thanks,

Dale could there be any debris in your fuel line?

"My tank was VERY clean when I installed it."

Is there a doctor in the house. Dale, you need to find a doc to lone you and endoscope! Stick that sucker down the gas hole and look around. You might find something interesting!
