Fuel system bleeding tips

Just go to ebay and get one of these- BOSCH Genuine Primer Hand Oil Diesel Fuel Feed Pump 2447010038 2447222126 . Also the original primer pump is very difficult to unscrew because large spanner size and no room to actually turn it so i used so multi grips instead- the bosch one is much easier to tighten as smaller spanner size- i think 17mm from memory.

So, this one?

that's the one- you may as well clean the plastic mesh filter below lift pump if you havent done it yet.

Definitely clean this one on a yearly basis.

Still have to get around to that. I have to work out exactly which bolt to undo to access that filter. I'm reasonably confident about some things, but undoing stuff on a diesel fuel pump is not one of them, so I want to make sure I know exactly what I'm doing before I do it.

Chris,
IMO most 4BD1 fuel supply related issues revolve around this little screen/filter.
There are several threads on here about it. Search Perentie lift pump filter.
It is a small plastic screen that hides under the inlet banjo nut on the lift pump, which is almost inside the drivers side engine mount. 17mm from memory.
It is fiddly but not difficult to remove and clean.


Regards,

Even though it's in a difficult to access location it's really quite easy once you know how- it only takes me about 5 mins- no need to get under the vehicle but maybe put a catch tray underneath in case you drop the bolt/filter -use a short 17mm spanner to loosen the nut and then use your fingers to unscrew and try to hold the bottom of it when it's near the end of the thread- once out unscrew plastic mesh filter and clean/blow out and refit -preferably with new sealing washers.

If someone could take a photo and circle the correct nut, I'd be most grateful!
Seeing as she's laid up until my new headlights arrive, now is as good a time as any to do it.

it's the one underneath the lift pump -in the narrow gap between the engine mount.

Plenty of pics here ...

I put full instructions in post #26 of the below-linked thread

note the screw thread on the filter
