should i get like a pressure tester or something and see if i can push the thing open with boost or vacuum?

It's easier just to get a pressure gauge with a T-fitting to measure the actual fuel pressure in the system. https://www.nopistons.com/forums/pub...IR#>/smile.png



BTW, I can maybe get 5psi of pressure blowing into a hose. I dunno how you guys are trying to make the stock FPR bypass at 35psi!
