Clamps on Connecting Fuel Hoses
#41
It took me quite some time to realise what you meant by keeping my own fluids up, and "JD through a straw" - Jack Daniels, I assume...?
Loads of rags it is, then. Open air is no problem. Nothing but open air. Too much open air... And if the barbs look wonky, carefully, carefully smooth them (the goal being to make a neat circle, or the goal being to get a crisp edge to grab the hose with--or both, I assume), and then if the connection is dodgy, get some proper EFI clamps as the current ones look generic.
My first priority, I think, will need to be the aircon coolant leak. The fogging is getting ridiculous, though today, being cold and wet, was a day designed for fogging anyway. But the defroster struggled. I think it gets worse when I use anti-fogging stuff, actually. Only on the left hand side, however. It might be just the o-rings for the heater core pipes. I shall do some research....

You are learning, well done.
If the barbs are suspect, take a thin strip off the emery, and form a circle with your thumb and forefinger, place the emery inside that circle, then the spigot (barbed section), inside that emery circle, close the gap, and rotate the spigot in that circle, thus "smoothing" the sharp edges to a dull edge (which will not damage the hose) when clamped.
I did ALL mine, takes the guess work out of the whole exercise.
Some of mine had serious DEEP cuts across the barbs, Gorilla Rocket Scientist before my ownership, so I use a very fine, very small file to get them out. My wife came to that rescue with a nail file, worked a treat, women, gotta luv their thinking, sometimes.
It is surprisingly easy to damage those sharp barbs, and equally easy to smooth them down to accept clamps.
You are probably on the money with those o/rings, very common.

Thanks for the tips. The idea is to remove anything that might tear the hose, I gather. And remove anything that might let fuel leak out, like a gouge. I think there might be some nail files around. My wife won't let me use hers, that's for sure....
I'll do some research on how best to get a look at the o-rings -there's quite a bit of info out there, and I just need to collate and sort it so I know what I'm doing. From memory, the pipes are on the left, so access from the passenger side should be relatively easy.

Incidentally, KWE has another criticism of using clamps: "...conventional hose clips are not suitable as they leak after the pipe hardens."

Clamps on Connecting Fuel Hoses

Hi Last Chance (quick edit lol)
I have no idea if you can buy these Fuel Hoses or not but I certainly would not want to be driving around in an XJS with a Fuel Pipe that only leaks even when its cold, as one day it might start leaking when its hot
At which point it could start a Fire that may not be too easy to put out
So I think you might be better off going to your local hydraulic shop and then ask them to make some up for you out of top quality fuel hose

Motorcars shows one currently: https://www.motorcarsltd.com/eac9987.html
If one hose is leaking, you might want to replace all of them: https://www.motorcarsltd.com/eac9986.kit.html

I have a question on your photo and this topic of fuel hose clamps, my 91 XJS appears to have had new hoses installed and you can see in my photo the use of screw clamps on this section between the right rail and what I think is a fuel pressure switch. I get a leak on this section upon initial startup o& the engine and the leak stops after the engine warms up and the pressure switch apparently opens and reduces the line pressure at this hose section. My question is can one buy these factory OEM hose sections of is replacement with or without clamps the only answer. I have checked these tightness of the metal threaded connections of this section and they appear to be tight, indicating the leak may be from the hose where the clamp is locatated. Thanks in advance for your response or that of others.
