Hmm another quadrajet issue

<< < (2/2)

The carquest pump was made by airtex and the pressure was a 9.5. Went to a carter and pressure dropped to 6.5 so should be good on pressures now.

I've been down the fuel pump high pressure road before. Causes all sorts of issues. flooding/ fuel forced thru the primary nozzles and dripping  , Hard hot starts. Heat expansion of fuel trapped in the lines between the pump and carb can rise and overcome the needle/seat.
I tapped in an inline direct read pressure gauge near the carb to keep track of fuel pressure.
