Disco 2 Fuel leak fix.

What a day, learned a few things, but not there yet, bit of a nightmare in fact lol, put the regulator on, and was screwing the second pipe onto the FPR and it cross threaded, bugger took it all off, reconditioned thread, built it back up (with the stub on) pipes back on purging fuel, oh it's not leaking, not possible ah there we go no leak from FPR, but a leak from the cooler, woe is me, question can it be bypassed, repaired, I've obviously put a bit of pressure on the pipe, 17 years old, deffo parts on it not happy with age.

Fuel cooler, is also in that website Discovery 2

Had a look at that post neilly, unfortunately its for a collant leak, not a FUEL leak, he is very like myself, in preferring to fix rather than replace whenever possible, £200+ for the cooler was the stealership price

Are you sure the connections are fully pushed on and in place correctly?

Aye mate, the fuel is bubbling out where the elbow attaches to the round body of the cooler !

OH,

Well there is a technical term for that.........I guess you know what it is.

Aye, ordering one up just now, then I will see if the old one can be repaired, technical term has been in use lots this weekend

It helps to have a selection of technical terms handy in case one becomes less effective due to over use.

Been busy, put a few miles on the disco 2 after fitting not only a Fuel pressure regulator, to which I fitted a service kit, but also a fuel cooler, which sprung a FUEL leak, tricky work, took FPR on and off THREE times, for one reason and another, black belt now, I should add the bastard bottom bolt I eventually found quite easy not from the top, OR the bottom, BUT with a long extension from the wheel well.

its either diaphragm,gasket or o rings the rest doesnt wear, hopefully yours will better quality the ones i used

Been running the service kit a week now, seems ok not leaking yet, suppose I should cross those fingers

Jamesmartin, the kit I purchased was from i6, one point worth a mention is that the kit did NOT supply the thick "0" ring which holds the fuel filter in, and one larger "0" ring not used ?, so take care not to damage it, gaskets are standard "Britpart".

I've just replaced my FPR control valve, gasket and small pipe o rings, about 2 weeks ago, noticed a leak again getting really bad as to be undrivable diesel flooding out!!. I managed to take video via squeezing an old iPhone in the space underneath when the engine was running and it showed substantial leak where the circlip sits so assuming the larger O ring on the FPR control valve is letting by. The leak is not coming from the hole preformed in the valve. Just ordered a complete new unit. Noticed the leaking control valve fitted there is no small pipe sticking out the side, just a hole in the top, and not on the side as with others I have seen. Also I have read the fuel scores the surface of the regulator where the large O ring sits so causing the leak to worsen. Thats what made me now purchase the whole unit and not the service kit....again. Any comments welcome.

Now fitted new FPR unit, ran engine and no leaks....except for a new weep on the fuel return top hose going to the FPR, on the crimped joint nearest to the engine, the joint to the engine block, to replace this fuel line looks totally inaccessible unless dismantling of the intake manifold and associated bits. May just leave and keep an eye on this.

Doubt a fuel leak will fix itself.
