How badly is it leaking? Constant stream? A little bit of a leak? Generally, the volume of the leak will get worse slowly unless something is structurally wrong, eg split hose, failed quick connects, etc.

I'd take a look at the extent of the leak and then take a punt.

Good luck!

When mine was leaking, it was a steady drip at idle, probably every 2 seconds per drip, but when revved the dripping stopped.
Maybe your leak will slow when on the road?

I drove mine for about 3 months leaking and it started as slight weep but by three months was steady leak about 1 drip every couple of seconds, apart from using a bit more juice it will be fine, I have never heard of it stopping anyone driving. Should freeze over there anyway, diesel icicles hanging under the Rangie!

I'm at Fluid Seals and Packings at Artarmon and they supply these sizes! Just give them the code.

Well a small world it is!

How long have you been at FSP?

Once upon a time I ran a Seal Company in Adelaide and we dealt with FSP

Hi Tombie,
Sorry I meant that I was there at that very point in time, and wanted to share the love with aulro on where to get the seals

Cheers

Ok so I can confirm that the O ring fix is unlikely. Nothing wrong with the O rings I bought from FPS, but the leak is coming out of the diaphram itself. I'm trying to source a new Bosch regulator by Thursday, does anyone have tips on where to go?

Repco want to order it in at a cost of $180.

Cheers,
Clint

Just to amplify on this, IMHO if you have a leaking FPR it is wise to clean up the area by degreasing and get a mirror and light or a little camera thingo and have a good look at the FPR after a day or so.

I could see that mine was dry around the diaphragm, so felt confident to just fit a seal kit. The camera ( even the new Ebay one to laptop) was pretty useless and I got the best view with a mirror with light on a stick and lots of contortions.

If it is dry around the diaphragm you will almost certainly get away with a seal kit, but if there is diesel coming out there either the regulator oring is leaking or the diaphragm is leaking, and to buy a new complete assembly becomes a 50/50 propostion depending on how much you love cramps.
I will not say at present there are no leaks as this is bad Karma . Lets just say that so far the puddle volume has diminished greatly.

G'Day All,

Well, today I bit the bullet and after much cursing and swearing removed my leaking FPR, replaced all the O rings and then started to put it all back together again.

After much more cursing I completed the task at hand and eagerly primed the engine and started it. I git under the vehicle and to my dismay found a steady drip at 20 second intervals from the lower part of the FPR housing.

I did notice that the new O rings were a different colour to the originals which are black.

So, any clues on what to do next? I'm thinking about getting other FPR O rings and perhaps a new gasket and if that does not work I guess I'll have to spring for a new FPR. Not looking forward to taking it apart another 2 times though

Cheers,

Franz
