Need help...not getting any fuel...
Permalink  

So here's my dilemna...put a new fuel pump on my 52 with the stock 239 Flathead, and I don't have enough pressure to run it.  I'm running through an electric fuel pump as a back up...could this be restricting the flow?  Any ideas?  Need her running for the WOW next weekend...Thanx

I agree with the statement above.

You can built a bypass with a manual valve to operate your mechanical or electric pump.

check your push rod travel , flatheads notorious for worn camshaft lobe driving the pump.

I was thinking about the "lobe" issue, but the new pump I got has a wider surface than the original...probably twice as wide...I will bypass the electric pump and try that...Thanx alot for the help.

Do you know that your feed line out of the tank is clear? Is it an old original tank that may have a good coat of varnish inside the tank on the inlet?

Just for fun, what if you try a hose from a jerry can beside the car, eliminating all but the line from the pump to the carb?

Thanx...got her figured out...bypassed the electric pump and removed the filter at the carb...now have an inline between the mechanical and the carb....seems to run good now...she does sputter and fart on occasion though....let her sit and she's fine again....vapour lock maybe?

You wouldn't think vapour lock would be an issue in these temperatures would you? I thought that was for hot summer days.

Only spitting when it's hot? Coil maybe, condenser, point adjustment?

I remember guys saying that hot misfiring was sometimes the condenser in the old distributors. Cheap stuff to try at least...
