Thread: Fuel pressure reg still leaking

happened to me too...those o-rings in the repair kit are not the best quality IMO... new genuine FPR is the real cure and it will last for long

I replaced the full block, genuine, and new gasket (correct the 2nd time around) but it's still leaking
I'm probably a hack mechanic though

Same here, o-ring kit fitted by mechanic, still leaked, so new unit fitted, now ok.

hmmmmm

...and again. Tried the cheap repair (eBay service kit) - still leaked. Replaced the entire fuel regulator with genuine part - problem sorted.

By the time I was fitting up the second time I found the job much easier as well. (-:

Mine was leaking and when I had a look, it was leaking from between the FPR and the head, through the gasket.
One of the bolts was not tight enough and the last person to work on it had added some sealant.
You have to make sure that the gasket surfaces are 100% clean and not marked in any way.
Mine has not leaked now for about 18 months,( So is probably due to die soon)LOL
I think that the lack of access means that it is very difficult to get the front bolt tight enough. That is why I removed the inlet manifold. If you are changing the whole thing including the EU3 pipe , then I IMHO it is essential to remove the manifold.

I replaced the 'o' rings about 2 years ago to fix a dripping fault at the time and this worked perfectly. Recently it has started to leak again, and I once again removed the fpr (following many scratches and cuts and verbal expletives) without removing the inlet manifold first. This is always a dilemma �� Whether to go through all the hassles of removing the manifold, etc... with its also difficult to get to bolts or maybe just trying to work around it and try to get the thing off without touching the manifold. It always seems to be after the skinned knuckles and frustration that it would have taken longer but in hind site it would have been better, to have remove the manifold first. Anyhow, after battling to get the fpr off, replace the 'o' rings and then refitting the unit.... it still leaked!! �� On close inspection I noticed that the leak was actually coming from the diaphram and not due to a faulty 'o' ring.
I have ordered and just received a couple of diaphram kits (diaphram, gasket and 'o' rings) from the OE supplier in Spain and hopefully will be able to fit this in the next couple of days. Of course, being a LR, it is not possible to just get a pair of circlip pliers in there to remove the clip , slide the old diaphram out and the new one in and replace the circlip .... you need to go through the whole skinned knuckles routine again ��... good on ya LR.
I will post back here again after the new install to advise the outcome. ��
