ok guys i have been away for a while at the beach but im back now!! and ever since i installed my new gas tank i cant seem to get the fule pumped to the carb. now the fuel pump is working but i am not sure if it is working 100%. B/c about 2 months ago i took 5ft of fule line and ran it into a 3 gallon gas tank and the gas pumped straight to the carb. and the other day i did the same thing with about 3 inches deep of gas in a 3 gallon tank. I got no fuel pumped to the carb. what could be my problem?

do i need more gas in the tank b/c the fule pump isnt strong enough?

Quick thoughts...
-no gas in the gas tank
-air from tank not allowed to escape (vent/vacuum situation)
-kink in the fuel line
-blockage in fuel line
-clogged fuel filter
-bad fuel pump, or fuel pump installed wrong

Have you disconnected the fuel line before the carb, cranked it and checked for fuel?

there is half a tank in the tank
-air from tank not escaping could be it. how would i fix that?
-no kinks
-just cleaned filter
- and yes i have, i also have a glass filter so i can see it

Just verifying...youve disconnected the fuel line at the carb, you can crank the engine, and see fuel coming out (like into a glass jar, etc.)? If so, then Id say the issue is carb related unless your fuel pump is only kicking a trickle of fuel.

Others care to jump in....?

no i have not gotten fuel to the carb yet. i cant even get it to the fule pump. all my lines are dry, b/c its a brand new gas tank with half a tank of gas in it

It takes a little bit of cranking to get fuel up the lines. After a few crank 5 sec, wait 30 sec cycles you should get fuel at the carb. If not, I am guessing though that you may have a kinked line at the sending unit or junk in the lines.

i have cranked it for 1min befor and got nothing. now i did bend the tube by hand to get it in there but i tested it and gas could pass through it still. that couldnt be a pproblem could it?

Get a hand vacuum pump from the auto parts store and try to pull fuel up through the lines to the fuel pump.

If it does not work you have a problem with the sending unit or lines.

ok so i tried the hand heald vaccum pump, it brought fule up and i have come to fiqure out my fule pump is bad. thanks for the input

Next question. When you fed fuel in from the gas can, did you run straight to the carb or through the fuel pump?

If through the fuel pump, then your fuel pump DOES work.

Find the leak in the line between the fuel pump and the tank. Air flows much easier than gas, so your pump won't pull fuel if it is pulling air.

Now that the line is full of fuel, connect it back up to the fuel pump inlet and see if fuel goes up to the carb.

did you smell your oil to see if it has a gassy smell to it there might be a little tear in the diaphram. its a quick pull the dip stick and smell.is there a test for fuel pressure on a car that old.
sorry just ideas im a bodyman by trade lol.a friend of mines grand torinos crank case was full lol and man did it smell like gas.car was running fin i just checked the oil while he was gasin it up lol saved his engine.
