Replacing FPR


Recommended Posts

How hard is it to replace the Fuel pressure regulator on a northstar. Isn't it connected to the fuel rail above the manifold? I think it has a little clip to pop out.

I'm just about to do mine on a 1996 El Dorado - it looks as easy as you suggest. Just a clip. I'm expecting some fuel to squirt as it depressurises, but that's it.

Other models have the FPR buried deeper and require more work...

Locate the valve to attach the fuel pressure guage. Looks just like a tire valve. Remove the cap and put a rag over it. Then press the valve (just like letting air out of a tire) to depressurize the system first.

quick tip, when you pull the FPR out it should have a rubber "O" ring on the bottom, if not, its still in the hole.

I just used a pocket knife to get it out. The new one should have one on it or in the package.(I spent 5 min. trying to put the new one in before I realized <_< )
