LB7 Fuel Pressure Regulator on LLY

[Duramaxduner]

Does anyone know if an lb7 FPR will work on an LLY? Has anyone done it?

a quick search will tell you that yes, it will work just fine with no tuning changes needed :thumb:

Awesome. Some people say it works just fine and I have seen one guy say that the LLY fuel pressure regulator has a higher KPSI than the LB7 version so it doesn't work right so I was wondering if anyone has actually done it. Ill install it tonight and report back.

because he probably has an 06 LLY which is really an LBZ

The only difference between an LB7 and 04-05 LLY regulator is the 90 degree plug on an LLY VS a straight one on an LB7.

Just installed last night. Works fine. Little tight putting that Y bridge intake back on but not bad.
