Starving out on hills
I have an old crate-350 in a '66 Camper special C-20. When I start up any kind of hill it is starving out and just about stalls out. I can back it up the hill (like a tin-lizzie) and the truck runs smoothly. Going forward (uphill) though is just not possible.
It has an electric fuel pump, works well, as far as I can tell. I put a new mechanical Fuel pump back in and still have the same issue. Tried it with the electric and with the electric by-passed. It still does the same. Pulled the sender/intake module from the tank and all appears to be fine. The brass fuel screen cylinder is in beautiful condition. Amazing considering its age. So there's nothing blocking the fuel supply. Would water in the tank do this? That is to say, run fine till I attempt a hill? Found out why my fuel gauge isn't working. The ground was broken. Fixed that when I put it back together. I'll replace it with a new wire later. So I'm stumped. Any ideas of what else to look for? |

Re: Starving out on hills
Reverse is a lower gear so does not need as much power. I would be looking at the ignition and timing. All motors need fuel, fire and compression. So when looking at low power I start with compression, when all the plugs are out they can tell you a lot about what is going on in the engine.

Re: Starving out on hills
You didn't mention but I'm assuming you have an automatic transmission.
If you park the truck uphill does it still act like it's starving for fuel? Maybe put it in neutral as it's trying to die out. This would let you know if it's in fact fuel starvation or transmission related. I had a dodge van that did that on steep hills but it was transmission. If you are certain its fuel related, lift the top of the carb off and check the float level adjustments. Also, place the fuel line going to the carb in a plastic container and check that it pumps at least a pint of gas in less than 30 seconds.
