Should the fuel pressure reg go before or after the filter upstream or down stream? right now i have it before and it keeps clogging up the filter. runnin about 74psi.:rock:

I'm pretty sure the regulator goes before the filter.

74 psi? Maybe your muffler bearing is loose?

yeah i think my muffler bearing is fine i just replaced it about a year ago other than that im runnin 74 psi because its a prototype multiport fuel injection system and without at least 70 psi the injectors wont open
