My tow rig had a problem with the fuel pump [stock carbed 460/auto] and I changed it with new just before heading out on a 300 mile trip. On the way back I had problems again. The pump went down to about 3 psi and wouldn't keep the truck running. After waiting for the tow truck for an hour I decided to do another test and it was up to 5.5-6psi. I started up and carried on home with no further problems. Now I'm worried about taking any more long trips. What could be the cause of this drop in pressure, especially since the pressure comes back with time. Heat? I don't have a book handy, is there a fuel filter before the pump? Is there a sock on the intank line that could be clogged intermittantly? Other ideas? I'm going to look at it right now so any suggestions on how to proceed are welcome.
TIA,
Richard
