coyote kid Posted June 21, 2013 Share Posted June 21, 2013 what fuel pressure does my 88 Comanche 2.5 run at ??? Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted June 22, 2013 Share Posted June 22, 2013 Fuel pump should deliver about 14-15 psi and the regulator should lower it down to 9-10 psi. I don't know if there's a test port/schrader valve on the '88 2.5, but I haven't been able to find one on my '86 2.5. I just took an educated guess and replaced the fuel pump. No more stalling now, so I guess that was my issue. Link to comment Share on other sites More sharing options...
