Injection manifold fuel line help

[Ajbrisso]

The stainless steel fuel pressure line that is in the engine compartment going to the enjection manifold is leaking on me. I changed the head gaskets and during reasembly I went to tighten down this fighting and was holding onto the 90 while tightening it, and i ended up cracking it. I've tried JB welding it it but that doesnt hold up to gas, and then i put seal all on put that doesnt seem to be holding up to the heat.

So now I cut the fitting off, installed a 90 and a barbed fitting, a high pressure fuel line clamp, and that is leaking. So now i goobered up a bunch of seal all around everything...

Im wondering if anyone else has had an issue with this or if any one has a suggestion on how to get this fixed. I've searched and can't find the fuel line and i was fighting to get the quick disconnect disconnected without any success...

Attached is a photo of the line I am talking about.

Also, what is that metal thing that is crimped onto the line?

Best bet is a wrecking yard, generally DIY high pressure fuel line repair doesn't work well.
Or remove the fuel line and take it to a shop that can install a high pressure fitting on it.

"metal thing" looks like a pulse damper, it keeps the pressure stable as pump comes on and goes off and also when injectors open and close

Yeah i havent had any luck with a DIY fix...
Never thought about finding a shop to install a new fitting. I'll have to see what I can come up with.

I take it the pulse damper has to stay on?

Removing pulse damper might not effect you overall but MPG would be effected and random mis-fires would be higher.

The Computer opens the injectors for very short time, milliseconds, this timing is based on what it gets from the O2 sensors, so it is a dynamic system, i.e. changing all the time.
If injector opens just as fuel pump turns on it would inject too much fuel, showing rich at O2, so computer doesn't open injector as long next time, so now O2 shows lean and you may get a mis-fire.
This all happens very fast, and computer would handle it but you would end up using slight more fuel than needed and get the random mis-fires.

Car makers are cheap, they absolutely do not add things that are not needed.
They may be forced to add things in the emissions area but not in the fuel supply area so I would try to keep it.

Sounds good, I guess i'm going to have to try and source a fuel line from a junkyard.

While finding a Ranger fuel line from the same engine and year would be great, fact of the matter is as long as the threaded fittings are the same a pressure fuel line from Subaru would work, lol.
Just measure the length you need.

if you are willing to just spend a few bucks and have it done, take the line into a shop near you that deals with hydraulics and high pressure systems. they should be able to hook you up.
