<" If replacing fuel lines, I would say get rid of this fitting and run a single piece of fuel line from the pump all the way back to the engine." >

Almost precisely what I did when I installed the Subaru 2.2L in my '91 Carat. Instead, I replaced the rubber hose between the plastic tubing coming from the fuel pump and the steel fuel inlet fitting on the engine, sans the plastic fantastic intermediate fitting.

The plastic fire-wall fitting disintegrated in my hands during the engine change while pulling the engine side hose off, and it was indeed scary.

It appears as though it was originally there to facilitate a convenient disconnect when removing the engine. Too scary to replace, in my humble opinion; I'll remove the fuel hose from the engine inlet when I have to yank the engine.

By the way, I believe this plastic fire-wall fitting being discussed is found only on 2.1L '86 to '91 2wd vans. The Syncro I have uses a brass union instead, and an '85 2wd I looked at tonight doesn't have one either, unless someone else had already eliminated it before hand.

While we are on the ever scary subject of engine fires and how to avert them... When I got my bus, among many other neglected items it had a fuel leak just behind the firewall (out of sight up over the transaxle)... it was making such a fine mist you could barely see it but sure could smell it!

Turned out the leak was coming from the back side of the plastic barb fitting that takes fuel thru the firewall into the engine compartment. (white plastic barb on the forward wall of the engine compartment) Fuel line comes from the pump to the back of this fitting up out of sight behind the firewall, where there is a junction (not even clamped on my bus, just a pressure fit!!!! a leak waiting to happen which indeed it did)... then inside the engine compartment another short section of fuel line goes from the barbed side of the fitting to the engine itself.

Anybody know what the heck this barb fitting is supposed to be good for? Other than adding two potential leak sites to the fuel system! I think it is like the human appendix... a useless relic of evolution, usually does no harm but if anything were to go wrong you really wish you'd had it OUT already. If replacing fuel lines I would say get rid of this fitting and run a single piece of fuel line from the pump all the way back to the engine.
