Thread: Bleeding Td4 fuel system.

Not straight forward without the right tool unfortunately:

Defender2 - View topic - Bleeding a TDCi?

Thanks for that. Will try to source the fittings and make a pump. Might have a go at the air compressor method to get me going this weekend. I wonder if Ford use the same tool on the transits.

Got it started by unclipping the fuel line at the rail and pressurising the fuel tank with the air compressor. Handy trick if you get stuck but will still make up a pump if ever needed again.

I had the same problem with the first Puma we had in the shop. We got around the special tool by hooking up a pipe to the special tool port and using a brake bleeder vac tool we were able to fill up the filter. Fired up straight away after that. Trick is (as mentioned on this site somewhere) is to fill the new filter before you fit. It wont need bleeding then.

Use a brake bleeder as previously said, or the transit tool, or any universal fuel hand primer should fit with little trouble.
Worst case and I mean WORST as in you are in the bush and have no option.....remove the air intake from the air box, get someone to crank the engine over and spray silicon spray or brake cleaner in the intake in SMALL SHORT bursts. The engine will run on this and cut out unless you keep doing it until the injection pump has pushed all the air out and is siphoning the fuel up from the tank as it should.
I can not stress how LITTLE you should give it from the spray can though as your engine will run on this and it will rev till it blows if you give it too much in one hit.
This is a last resort method only.
(But I've done it loads! )

Pressurising the fuel tank breather is another option. I'm just about to run mine up into the engine bay with a fitting that's compatible with my compressor - makes things quick and easy.

I could be wrong. But I think that somewhere on the net I read something (was in context of megasquirt petrol! ECU systems) about silicone having bad effect on lambda sonds. It needn´t have to do with silicone spray. More likely with silicone sealant. [unsure]

(just because the TD4 has a lambda sond. The 2.2 has)
