#98 of 100 97 Pressure Regulator by bluejay5 Oct 13, 2009 (5:28 pm)
Have a 97 blazer with fuel pressure problems. Pressure at the fuel rail about 7lb and falls to 0 as soon as pump stops, took the line off at the output of the filter and can NOT hold the pressure back with my finger so i figure the regulator is bad. I also have a 95 that I replaced the regulator assy. about 7 months before the tranny took a powder at 180K. Since both are engine code W shouldn't I be able to use the one use the one from the 95 and put it in the 97? Just trying to save some cash in these times.

Replying to: bluejay5 (Oct 13, 2009 5:28 pm) Easy way to check, go to an online parts store (Autozone, Advance, O'Reilly) and look up the regulator for both year models. Chances are it will be the same part number for both.
#100 of 100 Tarry looking gas by whitemfox Oct 14, 2009 (1:24 pm)
I have a 96 Blazer w/v6 vortez, I have been having trouble with it starting, I need to prime it to get to start then it seem to run ok although it reves a littel high when drving. but because of that I have changed the fuel filter several times because when I take it off the gasoline looks blackish and tarry looking and I cannot figure out why any suggestions The fuel pump pressure is a little of 50 psi
