Am getting my 1978 full size bronco up and running. It has the oem 351m and C6 in it. Driving it around today did real good till it got warmed good. run ok at low rpm but speed up some it would cut out like running out of fuel, i think it's vapor locking. Had a 79 F-150 with 351c do this years ago can't remember what i did to stop. I did put aluminum intake and Holley 4 carb. But the bronco is pure stock auto light two blr. carb. No headers oem air filter. Is full of fuel , is that old system a vented fuel cap. thanks for any help.

I had my 77 f250 with a 460 do that. I installed a electric pump and bypassed the mechanical fuel pump.
