While trying to start up my old Perkins for the first time in a while I found that there's a leak in the feed line from the tank filters to the lift-pump. Has anyone tried re-using swaged on hose fittings like these?
Reuse swaged fuel hose fittings?

Better to take them off and use a fuel line clip (not a Jubilee style clip).

If there is a leak why do you want to reuse it? Or do you mean you intend to remove the old fittings from the line, get a new line and then attempt to put the old fittings back on? Do you have the equipment. I normally go to a farming focused store that deals with hydraulics etc and they attach fittings with their machine. I have a hydraulic crimper but have only used this for electrics.

Thanks guys, the hose is rubbish and needs to be replaced, but it would be nice if I could reuse those fittings. I've got a Hydraquip store in the area, but I'm trying to do everything on the cheap if possible. Also not sure if they would have the correct fittings in store. This is on the suction side of the fuel supply so I was thinking maybe doubled up hose-clamps would do - and would allow me to easily replace the hose in the future. That's if I can get the fittings off somehow...

The crimp over the hose is not reusable but the fitting that fits inside the hose may be if its not damaged during removable.
When I replace the fuel hoses on my diesel systen I use double eye clips crimpling then myself using nail pincers.

Yeah, the question is how to get the fittings off cleanly. The crimped sleeves would of course not be reusable, but is there perhaps a trick to getting them off without damaging the fittings? Would Hydraquip perhaps have a machine that can do this?

[Heresy] Whisper it not, but a bit of PTFE tape would almost certainly cure the leak [/heresy]

You could cut at the ridges with a dremil or similar, but not too far up towards the fitting, then use some snips or pliers to peel back like you would with a tin can and key

I think vulcanising tape would be a lot better as a temporary fix, and I do have some of that to hand - but the hose is steel braided.

This is one area that should not be scrimped. The bits you are trying to save cost pennies at a hydraulics shop.

So you think they would have those fittings in store?

Most hydraulic guys will not reuse old fittings from my experience, the fittings are relatively low cost and the crimp ferrule needs to be new anyway.

Yes, I have removed the crimp sleeves and reused the fittings with new ISO fuel hose and new correct clips. I used a fine toothed blade in a junior-hacksaw. Saw at 45 degrees, then just as you get through the sleeve, rotate the hose a bit so you end up sawing a spiral around the sleeve from one end to the other then it is easy to open up the sleeve, snapping the final piece at the shoulder, to remove it.

Mostly called pig ear clampsThe crimp over the hose is not reusable but the fitting that fits inside the hose may be if its not damaged during removable.

I’ve used that method too. Go carefully with the saw and the fittings should be fine.
Whether it’s worth the couple of £ you’ll be saving is another matter.

That was easier than I thought - I assumed the end of the crimp went into a groove on the fitting, but turns out they're just slipped on. After some very careful cutting with the grinder the hose pulled right off together with the crimp, and not a scratch on the fittings. Took less than two minutes in all. Result!

The straight fittings does not look good as there are no sealing barbs when the pipe goes in and could be the cause of the leak

It also has a line running straight through the male end, with a nick at the very end which almost lines up. Would that line be normal?

Yes that looks like a damaged olive.
It looks like a bodged fitting.as I would expect a non swivel fitting if it is connected to the other fitting shown.
If not we need to see where both are connected.
