I’ve a 89 3.0 4x4 truck that has had its emissions removed completely, it seems to run fine but have found that the fuel pressure regulator lines has also been plugged off seems to me something that shouldn’t be! Any suggestions on were to connect the vacuum line to it without all the other gizmos that were once in play and would the relief line be connected to ?? Fuel return line or possibly charcoal canister line to tank? I have not been able to find the exact vacuum line information that fits this engine to figure this little issue out.
