Is It The Fuel Pump?

1972 Dodge Dart Swinger. 318, Eddy 600, dual exhaust, automatic, suregrip 8 3/4, factory air,

Was having a hot start issue and after great advice from this site, it is a lot better. We took the advice of many, closed off the crossover vents, added a spacer, insulated the fuel line, made some carb adjustments and it was running great. Sitting at a light, no power brake and punch it and she'd light 'em up until...

had her at a car show where we had sat for close to four hours, she started right up and as a bunch of MOPAR guys were leaving the lot they were lighting it up so I decided to jump in and she stalled.

Started right up punched it again and same thing.

We brought it home and by the time we got home it was running great.

A couple of days later we started it up, drove twenty minutes to a friends and started looking everything over and it was running great. Chalked the tires and burnt out in his garage.

Three days later another car show and as we were leaving we went up a pretty steep hill and she stalled. Really didn't punch it just gave her some gas to make the incline.

Next week we went to a car show and I babied her and had no troubles but it was really bugging me so someone suggested I change the fuel filter.

This past Saturday it started right up and I drove to the parts store and as I pulled in their lot which has a slight upgrade, she stalled.

Bought the filter but didn't get installed. Later that night at a show we were talking with a couple of MOPAR guys and we explained the trouble and they suggested the fuel pump.

They felt like when she's sat there is no pressure. Run a while and everything is fine.

They suggested an Eddy EDL-1720. 6 psi.

Thoughts?
