Does my fuel routing look correct? 94 chassis and bottom end, '99 head and rail, '91 FPR. The quote below references the fuel injection fittings from a late NB...are they referencing the quick disconnect fittings (versus just slipping the fuel line over the rail)?




"You will need to retain one of the fuel injection fittings from the 01-05 fuel rail to use as an adapter on the 99-00 fuel rail. I prefer to use a 90* adapter instead of a straight adapter to aid fuel line routing around the alternator. Do not simply slip a fuel hose over the end of the 99-00 fuel rail - it will not stay in place. Use 5/16" fuel hose to run from the feed line to the 90* fuel injection adapter and into the fuel rail. For the return, install the 90-93 FPR upside down in place of the OEM 99-00 fuel damper (fuel outlet facing up). Use 5/16" fuel line to run around the back of the intake manifold and into the return line on the chassis. The fuel pressure will be 43psi with a pressure reference, just like the 1990-1993 fuel system."

Yes, they are talking about the quick disconnects, and warning you not to just use a hose and a clamp.

The NB uses nylon lines over barbed quick disconnects, it is possible to slice off the nylon lines and reuse the barbed fitting with rubber hose if you're careful, but personally I would buy the Dorman adapters, they're actually designed to do it. They're cheap and available at Amazon.
