Thread: TD5 Fuel Pressure Regulator Leak

Doing mine this weekend. Do you have to release the fuel pressure like in petrol cars by pulling out the fuse before you take off the hoses?

Also what's the bleeding procedure after doing it? Something with pressing accelerator 10 times or something but I forgot

I found this on ebay which is a complete rebuild kit excluding the housing only. For $60 odd delivered cant beat it. And it comes with both types of metal gaskets - 2 and 3 hose versions, all orings and 4 bar pressure regulator.

eBay Australia: Buy new & used fashion, electronics & home d

This kit that Toppa mentions is what you need,
the regulator or the seals under it were the the culprit on mine. The new reg (comes with viton seals) is much better because it has a pipe on it & I connected a neoprene drain hose to mine, so if it leakes in future it will drain away in a safe place insted of onto the starter motor.

Save the $$ and do it yourself, its an easy job.

The reg is on the low pressure side, you dont have to bleed or anything

I did mine last Friday night. The biggest hurdle was getting that lower bolt out. It took most of my time. No issues with fuel pressure I just unbolted mine and a small amount of diesel came out. Getting it back on with the new gasket is another issue. I put the bolt at top closest to the front in first with the gasket on. Cable tied the other top hole to keep it all in line. Tightenned the front bolt slightly so the gasket wouldent move and then cut the tie. Before that I removed the filter and cleaned with brake cleaner and replaced the o-ring while I was there. Don't drop the filter, and make sure you have the new o-ring in place firmly and be careful not to bump it when reseating the reg. Bleeding air is simple. Turn ignition on but don't start the engine. Press accelerator down all the way and back 5 times or so until the engine light flashes. It will do two minutes or so of cycling.

Actually Im going to retract my last post. The Fuel Reg kit that Toppa mentions, I bought & installed about a 5000klm ago.

Towing the van up the Hume Fwy today I pulled over just past Wang for a leg stretch & noticed a wet spot under the landy. Bloody new Fuel Reg kit is leaking, Enough to fill a tea cup in 1/2 hour , At least its coming out the neoprene hose & not all over the starter motoe & Crank sensor.

Rang Ivan Clark in Albury & you wouldent beleve he just sold his last one to a walk in customer 1/2 hour before - SpewING , Have to keep going & pick one up in Sydney tomorrow,

So I take back what I said & will be buying the complete Genuine part.

Bugger, i was going to install it this weekend as my old one is pouring out. I think i still will, but my expectations have been somewhat diminished.

Yeah did mine today. I reckon I spent over an hour trying to get the lower bolt off, the rest probably took me about half an hour lol. Ended up getting it off from underneath using a ratcheting spanner, those things are worth every cent. Whoever managed to get that bolt off from the top must have some serious skills lol

I got mine by braking my arm in two places behind the manifold. Not so bad once you take the hoses off. I originally tried with the hoses on as stated somehwere else online. I started having anxiety attacks and decided to take the hoses off.

I did mine on Saturday along with replacing the seals in the Abs.

So far no leaks. We will have to see how long that lasts given the report of the same kit as mine not lasting very long. I reckon i could do it pretty quickly now, if i do have to do it again.... Fingers crossed i dont have to.
