I just put in a new fuel pump and gas line from the pump to the carb. Can anyone point me in the right direction or recommendations of what to check next? The carb is a Holley street avenger that was recently rebuilt that is on a 302. I just put 4 gallons of gas in the car and the fuel gage is reading right above E. When I prime the carb and pump the gas the car tries to start but sputters out. The inline fuel filter is not filling up. The car has not run since 08 and it did not have any gas in the tank the whole time it sat. Thanks for any help.
There is a rubber connection around under the driver floor. Check that for any cracks. Might just change it anyway. You can also use this to connect a longer hose and drop the end into a gas can to see if the pump will pick the fuel up from this point. The clog could be in the line from there back or even in the tank..
Earlier today I blew air with the compressor through the line before the pump to the gas tank and it seemed to be clear. Tomorrow I am going to test the pump by putting a line from the pump to a gas can and see if it sucks it up.
take the line loose at the carb. run it to a catch can. take your air hose and a rag, stick the hose/air nozzle in the filler tube and seal it with the rag. blow slowly into the tank until gas comes out the other end into the catch can. this will prime the line/pump from tank to carb.
you thinking he hasn't spun the engine long enough to pull the fuel to the pump? priming it with compressed air shortens this process...
also make sure your new in-line filter is turned the right way. that can cause the filter to not stay filled. Just sayn...
Today when I put the line in the gas can running into the pump it would not suck up the gas but instead blew air back into the gas can. I also took a 2 liter bottle and gravity feed the carb direct which ran for a few seconds then sputtered out. I'm starting to think the issue might be somewhere in the carb not allowing gas to enter very efficiently.
I would remove both lines from the fuel pump, put a finger over one fitting then the other while cranking the engine. Input's gotta suck; output's gotta push out. Be careful not to spray gas on yourself. Just wondering if the fittings were installed wrong in the new pump. BTW, I had to return two fuel pumps before I got a good one. A fuel pressure gauge installed on the fuel line would let you know what's going on. They're cheap.
