I installed a JG manifold on my b18c1 and my stock regulator hit the manifold. So I swapped it out with a factory regulator that the return turns towards the left. I think its off of a 88-91 sohc. Now my fuel pressure at idle is like 38psi. Do anyone know which factory regulator will fit with a jg manifold and str rail?

 

Sorry man i don't know but here's a bump for you, hopefully someone else will have an answer for you.

 

I don't know either but why would run a factory regulator with that type of motor. I would go ahead and get an adjustible one. I'm sure you'll need it down the road.

 

Just keep the one that fits and put a B&M on it.
