Philippe,
If you've got good line from the front of the car all the way up to
where the sender unit enters the tank, I think you have hit the nail on
the head. Sounds like the tank needs to come down. This does
happen....

Hi,
Since 1 week my car is "sleeping" in the garage with a fuel problem ! 1
week ago i put a new rebuilt mechanical pump, filled the tank and
started a 200 miles trip. I made only 10 miles, at the first hard grade
the engine began to miss ... Come back home w/o problem (and took the
roadmonster !).
This week i tried to solve the problem which was, i was sure, the "new"
pump. First i tried monday to start the car. Nothing !! Starting motor
ran but the engine coudn't fire.. I remove the output hose of the pump
: no fuel if i ran the engine .... So the pump was bad. I decided to
re-install the Holley electrical pump but before i made some test with
the "new" pump off the car: the pump works when i made several stroke
with the input hose in a jerrican !
So i installed (on the ground, at front, with flying wires) the elect.
pump. Input was at the fuel tank to pump end (near the front wheel)
and output was in a jar. By chance (and because i haven't other hose) i
put a clear plastic hose as input hose of the Holley pump. I connect
the 12V and saw that the pump delivers just a little fuel (1 pint in 5
mn !!) with a lot of air bubbles, sometimes no fuel, then a little,
with erratic flow..
I thought that the pump wasn't in "the good place" (note that i tested
it before with a jerrican and the pump delivers a lot of fuel). These
electrical pumps must push and not pull. So i installed it at the rear,
near the tank. Same results !! Can't supply fuel for a 1/18th thermic
car !!!! And as before, air in the fuel ..
I thought that i've an air leak somewhere between front and rear of the
rigid line so i made a test pressure : i plugged the rear end of the
fuel line (between rubber hose and fuel sender unit)and applied 30 PSI
at the front end of the line. No leak !!!
So it seems that i've an air leak in the fuel sender tube (at the upper
end because the tank is full ..) !!!
Someone has still have a problem like that ?
If you 've some ideas ...
One of the reasons this is soooo long is to
try
to help Phillipe
Courant sort out some of his drive line trouble. I believe his car is a
'57 but, with the exception of how to tilt the 3rd member, the issues
are the same. I'll make it shorter next time.
Thanks Gary but at this time i must first resolve my fuel problem ... I
keep your mesage for future
