As cheap as block mounted fuel pumps are you should just replace it.

I've bought several the last few years for different vehicls and for a small block chevy they are about $15.

Other then that, time to drop tanks, pull lines, make sure they are clear by blowing through them with compressed air, and make sure the sock on the bottom of the pickups isn't clogged up. I'd replace thoose too they are cheap.

Then you can find the best looking tank and plum straight into only that one and loose the other if ya want.

it be cheaper the replacing the selector valve and all that stuff I'd think.


This isn't such a great idea, but I've done it before lol, if you can find the main fuel feed line out of either tank, or just one going to the fuel pump, you can disconnect it, run a long piece of rubber fuel line down into a gas container, and try and start it up that way.

If it does start and run, the lines are free from there to the carb and the fuel pump is good. If it doesn't then change fuel pump and clean the lines out.

I did that on a 76 because the tank had lots of holes, I ran my line up between cab and bed and put the gas jug in the bed, out of harms way and any backfires.
