I am in Mexico, have put two new "Chinese fuel pumps in my 93 chevy blazer 4.3 vortec, TBI model. 1st didn't work, 2nd worked sometimes. Bought Carter at PepBoys, didn't work at all. One time I saw pressure at about 55PSI. GM says the AC Delco runs at 61PSI, Napa has a Federal Mobile unit they claim puts out 65PSI. Could my problem be as simple as inferior pumps?
have the same problem?
