at this point, i have really ruled out Vapor lock, i have not had the car running long enough and hot enough for Vapor Lock, i apprently have a fuel problem, tank, fuel pump, fuel pump rod
or ???, hopefully when i do the test tommorrow i can determine if the pump is pumping a steay stream.
thanks

so i need to take the rod out and just measure the rod?

1st do Joe's test w 2 jugs. W the carb bowl full (fill it 1st w a turkey baster) you'll have 5-10 seconds b 4 the bowl runs dry & that'll be enough time to see if the pump is pulsating a good stream & if not then yes take out the plug & the rod

thanks Robert, i will try that tommorrow, i saw the lady across the street today and she was giving me evil eyes because i have been in the garage running the 440 all weekend

well I'm a firm believer in not antagonizing the old folks esp as I turn 60 next spring

she is just a sore head, she is not old, i think she is just an unhappy person, i guess when i get the car back running, i sound go over and ask her if she wants to ride in a real car

But do wait until she stops the evil eye. W women it's all in the timing. Good luck w it (the car) & holler back when you find something, I gotta hit the hay.

okay guys, i think i have narrowed it down to the fuel line from the tank and the sending unit, i really did not think i needed to replace since it was a daily driver for so long, i guess i am going to go ahead and replace the tank, sending unit and the fuel line? i have attached a pic. of the fuel filter while running from a hose put in a gas can, i let it run till normal temp of engine and it never fell before half full, is this where the fuel is suppose to be on this type of fuel filter?

i checked the rod when i put the new pump on, it did look mushroomed, however i did not take it out and measure it

do what do you think Robert, wld you just get a new sending unit or replace everything?

cornet684me,

I recently went through some fuel issues with my 68 Road Runner. New lines, new sender, new sock filter, etc. As the car warmed up I would lose fuel pressure and during my troubleshooting I installed a temporary glass filter and watched it fill up and empty out while running the motor. As it turned out one of my hose clamps holding the rubber hose to the hard fuel line was not quite tight. The clamp was close to the exhaust manifold and when cold everything was fine. As the engine bay heated up the rubber hose got soft enough to let some air in around the hard line and the fuel pump was sucking more air than fuel. I put a second worm clamp at that location and the fuel pump now keeps the filter full at idle.

Go figure...

Jim

update- dropped the tank, the tank is as clean as a new one, the sending you perfect shape, i am going to blow out the hard line, i guess i need to pull the fuel pump rod, i tested the pump and it tested fine, i have checked out everything and do not know why the fuel filter goes empty when the car is running?

hey Robert, i really appreciate you trying to keep up with my problem, i have already drop the tank, i will test the hard line tommorrow, i am going to hook up a hose from the hard line in the rear and see what happens, so if it test out then it wld have to be the sending unit right?

you know Robert, i do think that the gas is 10% ethonal, i cannot find a station around my house that says real gas, i have 1 station about 13miles from the house, do you think this gas is the problem?

here is pic of the sending unit, the inter gas tank is perfect, no rust and no dirt, no need to replace the tank,
