BACKGROUND INFO first:

fuel rail runs parallel to intake manifold
the FPR is on the passenger side of the fuel rail
the return hose is on driver side in center
high pressure fuel line is on driver side below return hose



I have the vortec SFMU and have no idea how best to install this.

I'm thinking that I should replace stock FPR with the vortec SFMU. If I remove the stock FPR, I am faced with the problem of blocking the open end up.

However, what if I remove the vacuum hose to the FPR? What happens? Does this leave the FPR open? or does this leave the FPR regulating fuel at a constant 47PSI?

heellllp.
