I recently bought an accufab billet aluminum adj. fuel pressure regulator and i was wondering if i needed to add anything when installing. Should i be able to just take the stock one out and replace it?
if I remember right when I replaced mine I got a little vaseline and rub around the seat where the regulator goes just a little yeah it shouldn't be no problem.
Probably doesn't matter much, if at all, as far as setting the fp, but with it plugged, the engine won't be running w/ a massive vac leak while you do it.... moving your blm's around, running like crap, etc.... and how hard is it to shove a golf tee in there??
