Fuel issue

135

Asked by Jul 03, 2016 at 08:00 PM about the 1972 Chevrolet Impala

Question type: Maintenance & Repair

Just rebuilt my carburater, fuel pump and
filter. I disconnected the fuel hose that
connects the line from the tank to the fuel
pump, I put the hose in a gas can and my
car crank right up. There are no holes in
the line that comes from the tank, what
could be wrong?

Try blowing compressed air through the line that goes from the fuel pump back to the gas tank. There could be a blockage. You also have an ELS (Early EVAP system). Make sure you have the hoses/lines hooked up correctly at the charcoal canister as well as the fuel pump. One is for fuel vapor and one is for fuel. I'd recommend getting a copy of the original factory shop manual for your Impala. This will show you a diagram of the fuel system and how all the hoses/lines are supposed to be hooked up. Faxon Auto Literature in Riverside, California will probably have a reprint at a reasonable cost. They have a website. HTH. -Jim

Can the "Evap system"block the fuel from getting from the tank to the fuel line??

And what size gallon air compressor do I need and at what psi?

Yes, if the fuel and vapor lines are mixed up you won't get any gasoline to the fuel pump. A compressor that can produce about 10 to 20 PSI should do it. Under normal operation the mechanical fuel pump only develops about 6 to 8 PSI. HTH. -Jim

So I fixed the fuel issue! Thanks, but now as soon as I fixed the fuel problem the car crank and turned back off, I tried to star it again and it just clicked! I waited a few minutes it started again then turned back off. The battery is new and now it's just clicking, could it be the starter?
