Supply fuel line from fuel filter housing to injection pump

[Aria clark]

Is there a alternative way to get rid of the metal fuel supply line from the fuel filter housing to the injection pump? I'm having a hard time finding parts and might have cut up the metal line. (For a 6.9lidi) I don't want to put the same parts back on it that leaked originally, and I want to be able to bend it out of my way if I need to work on something around the lines, without having to take it completely off.

I have another idi (7.3Lidi) that me and my grandpa put regular pipe threaded fittings on it, and a rubber hose (fuel rated line) but it's stripped the threads on that injector pump (or stripped the brass threads on said fitting) and I don't want to repeat that mistake.

I kinda want to get it going soon as it's already getting cold, and I have to bleed the air out of the lines again XD

That`s Push Lock Hose, so don`t use Hose Clamps on it.4

I put that set upon my 86 several years ago, works great.

The steel line from the Lift to the Filter can be replaced with rubber hose. Just swap in a Barb Fitting at the LP, forget what I used at the Filter end. It`s 3/8" hose.

Steel lines work good IF you use new rubbers.. They're cheap

I'm pretty sure that the steel line fitting on the LP is an inverted flare and won't take a NPT barb without a lot of praying. maybe someone could shine light on a barb that has a straight thread and sits in the inverted flare.

I've had the russ fuel line on my truck fir over a year, with no problems.

Getting the old rubber out is darn near impossible to do old my hard lines. I Bought new fuel olives only to find out that the old rubber will fight tooth and nail only to come out in difficult pieces. it can be hard to clear the original fuel olives out

my experience in this shows that a flared end will not seat against anything but another complimenting flared end, even with a kind of thread tape or o ring/gasket. It’d be a miracle if you didn’t have a consistent drip.

Oh good I'm not the only one... I'm pretty sure I had to burn mine out with a propane torch at least on one side, about a decade ago. Cause at some point I was gonna warp or scrape up the inside of the fitting so bad that it wouldn't seal after the surgery anyway! Worked well.

I had the same concerns, and was going to comment that I even tried with a propane torch. I did damage my lip a bit. Soft brass and.

With the propane, I think I made it a couple of seconds in before I said “forget this, I’m going to run russ’s delete kit.!”

I’m much happier with the AN fittings and soft lines, as I’ve switched to using a Facet Duralift lift pump.

You just have to burn out the rubber not melt the metal,
