So I swapped the new fpr and spring and piston for it. Trucks psi stayed the same sounded a little stronger but she still ran fine and got up to 60psi while wot in park and 40psi-50psi on freeway. When I took the spring and piston out, on top of the piston was like a black oring that looked broke on top and there was another sitting in the housing that came out after I cleaned it through with brake cleaner. I’m thinking it could be the fuel bowl one of the orings coulda broke but I got no air leaks outside when I had it running and was spraying soap water on all the connections outside while I had my son throttle it some so I’m still at a stump but looking more toward the fuel bowl
