Took apart the Inflator/Deflator and as expected there was a transformer, 12V - removed that and wired for power to the on switch of the ARB compressor, simple, compressor on, Inflator/Deflator on. The beeper removal is as simple as opening up the box and disconnecting it. Not really required for 4WDriving anyway.

Mine is a single pump ARB compressor- don’t think a double wouldn’t fit as the single is fairly snug.

Am actually hooking it up to a Jflex Auto Tyre inflator, like the inflators at a Petrol station, does inflation and deflation without the annoying checking and got it when I first started looking at the build. Sort of laughed when I saw it was an option on the new Defender.

Its a bit bigger than I thought but now I have got it, why not. Taking it apart tomorrow as it appears that the circuit board is just 12V (see the pdf page 8) so removing the 240V supply and wiring it in. If its not 12V will just use it with the invertor

Got finally genuine dynamic beadlocks rims 16x8

I have a fuel Pressure regulator leak!! It explains the odd diesel smell. About 2 drops a second.
Now the big question is....
Repair kit? Make and from where?
New unit? OEM? it is a Bosch part. Genuine is very expensive.
I have seen here about using two headless bolts to fit up the piece easily.
I am not looking forward to this, but It does need fixing.

Isn't the 6 cylinder Ford unit the same, also a Bosch item?

Depends where the leak is. Gasket can leak. Most likely actual regulator so any suitable can be fitted to housing, but new gasket and o ring desirable.
If it is really old the hose to the front of the head could be brittle so maybe a complete new unit required. Mine snapped like a twig when I bent it.
The front connection to head is VERY difficult requiring the making of tools ( thinned 14Mm OE with right angle near head of spanner) if inlet manifold not removed.

And don’t forget the fine mesh filter behind the fpr, pushed into block

This is coming out of the rear of the unit. From what I could see. I have a crows foot socket for the front pipe, that will come of easy. I have seen Bosch kit it has two different gaskets EU2 and EU3 and O rings. Youtube will help, I've helped with this and the owner took the inlet manifold off to get access. I hope to avoid that!

I’m sure I had mine off without removing manifold.

I have a very strong suspicion that it will do nada!
Had same tools, basically did nothing to help. The nut is too deeply recessed in between the manifold tubes to get most tools onto it to properly tighten it up.
I thought maybe a pipe spanner may get onto it too, but nope.

When we did brothers, in the end the only way for it to come off, I cut the pipe, used a socket and then fitted the short quick connect tube off the old regulator body. Slipped a hose over the quick connect bead and clamped.

It worked fine, but hose finally came loose after about 3-4 years, and drove me crazy trying to keep it on, which I finally managed and got home ... and next day, I then couldn't get it off again!

Recently I did manage to get it all fixed up tho, I had to cut the once slippery, now stuck! ... hose off. Bought some quick connect fittings, clamped hose onto quick connect and the hose is far more easily replaceable now.

If you do that front pipe/hose, no matter which way to go about it, make sure you replace the O-ring too.
