Need advice, have a 91 Sammi, fresh overhaul, mild cam ran good last summer. Had it in the garage over the winter, now it is running really rich. During the overhaul it got a new gas tank and fuel pump (old one quit, getting it out we saw the tank wasn't so good, replaced both). Wondering if the fuel pressure regulator may be bad since it's getting too much fuel. I checked the return line from the regulator to the tank, seems open. Not sure how to test the regulator... and it's $90-140 depending on where you price it. Thought I would ask you before spending that much $$...
