Thread: just cleaned the internal fuel pump filter.

I wouldn't put anything more than a sediment/water trap before the pump. Putting an actual filter before the lift pump is asking for troubles.

AND THE FILTER WAS CLEAN AS A WHISSLE ALREADY

Andyway, for my piece of mind, its been cleaned/checked now. Its the first time in my 5.5 years of ownership that its been out, and i doubt the previous owner ever checked it. Why did they put it in such a ........ of a spot, or why didn't they slot the engine mount to make it easier. I'm just going to put an inline fuel filter before the pump, so i dont have to mess around with it again.

I did the same job on mine a few weeks ago. Never had any trouble, just put a spanner (or was it socket?) straight onto it.

Was a bit of a fiddle though as it is close to the engine mount. I guess they must have changed something over the years (mines one of the last 110's - it's a 1990).

hang on, I'll pop outside and grab a photo of it.

OK, just out of interest... here's a photo of that Banjo connection on my pump, taken from underneath. Is that the same as yours?

Now I've looked at it, it's obvious that I used a spanner on it - but there was room between it and the top of the engine mount!

See how that metal bracket connecting between the engine mount and the block has a curve in the top edge? mine doesn't, its straight.

One day if the engine mount ever fails or it needs to be removed again, i will attack it with the plasma, and it will be the same as yours.

Ahh... No wonder it was such a @#$%^&* of a job then

After doing this job I also fitted an inline filter before the lift pump.

The Stage 1 Isuzu hand book says that model had a cav filter/sedimenter instead of only a sedimenter before the lift pump. It also had a filter on the motor. The service instructions are to change them both every 20,000km.

Yep had the same drama many moons ago but was like the pic was able to undo the banjo and find flecks of paint from the inside of jerry cans blocking it as the old girl just stoped on the side of the road like it had run outa juice ...

Inline filter was installed after the sedimenter to stop this from happening again

That's interesting.

My Isuzu was a japanese import truck engine, the banjo bolt isn't on the bottom, it's on the rear side of that block. There's also a manual lift pump on the same block.
