800 mile roadtrip

OK, this is a weird one, but: is your tank and pickup original? If so, it might be the problem. I have seen once where the fuel pickup in the tank came loose and would not reliably feed the pump below a certain point. (And boy, was THAT a head-scratcher.) Also...how close are your fuel lines to anything hot? (Exhaust, transmission, radiator hoses.) Today's crappy gas doesn't like heat, especially at high altitudes. (Rodeo, NM is at 4200'.)

Though...if it is the pump, a replacement (Carter) is about fifteen bucks from Rock Auto.

The pickup and sending unit are new. I replaced it not long after I bought the car. The tank is original, but it looked pretty clean at the time so I didn't feel the need to replace it. Not rusty or anything.

I did that mod where I did away with the factory hard line that ran across the front of the engine, and did a loop over the top. Not sure who recommended it... probably slant six dan. It's nice because I can put the line anywhere I want, away from all the heat. As a desert rat, that mod was mandatory.


Also... do you mean this carter pump? 1971 PLYMOUTH VALIANT Carter M4844 Carter Mechanical Fuel Pumps | Summit Racing

Notice it has one review? That was me. Yeah I know it says Ann, that's because I borrowed my mother's credit card to make the purchase at the time. Summit racing is weird like that. Suffice to say the pump didn't last very long.
