It doesn't look like anything will have to be cut. Looks like you can T in at the return rail, then get rid of the canister, and run a high pressure fuel hose a couple feet long to the fuel return line on the passenger front frame. No cutting necessary. I'm guessing you could then use a vented fuel cap and be done??? I can't get my fp regulated down either so I'm going to try this. I'm running a dw fuel pump and 80 lb injectors. My fp is ranging between 48 to 55 psi at idle with no control of fp. When I disconnect my hotwire to the pump and run off the stock harness, the fp goes back down to 42 at idle and is adjustable.
