My bronk hesitates when you snap the throttle. It runs fine when you gradually open it up. It even back fires if you do it fast enough....My first thought is that it's runnen lean so I put a gauge on it.

Ive got 35lbs. of pressure at the rail, but when I dump it I only get about a quarter of a pint in 15 seconds.

I'm thinking it's a bad pump but I'm not sure which one.......I'd think that it would be the one in the tank because the frame rail pump only pressurizes the fuel that is sent up by the low pressure pump.

Anybody know any specs for testing the pumps individually???

Oh yeah....the pressure drops on the gauge pretty quick after shutting the engine off

Any help would be great....Thanks
