While installing a GSR engine in my HF I couldn't get the fuel lines to work because the HF has a huge return line and the GSR regulator has a small return line.

To "cure" problem I installed the HF regulator on the GSR.

Have I screwed up the fuel pressure? I don't have a gauge.

I put a b18c in mine and just hose clamped it tight.

 

THe HF regulator bolted right on and allowed me to use the HF fuel return hose and a normal clamp, like what came on it from the factory.

It all looks OEM except I don't know the pressure between the two.

 

I did the same thing too. Since the hF line is way bigger than the gsr. I hosed a clamp down on it and make sure it doesn't leak. lol As long as it's not dripping, it's all good. Enjoy the horsepower

 

That's cool.

Do you guys happen to know the fuel pressure of the HF and the GSR?

 

I used the same pump and lines and filter assembly from the HF into a B16a.... I had to twist the line end to make the bend fit the Fuel rail end...but **** it worked....I don't think the Lines will do that much damage....keep us posted....i'm interested....you got my mind running..
