Fuel Filter and Pipes

[fozsug]

Morning Gents

Just purchased a 1990 Range Rover Clasic 3.9EFI Auto.

It was a non runner but very clean and cheep

I have now got it running, and pleasantly suprised, not tappety, not smokey etc.

The reason it was a non starter was someone had replaced the fuel suply and return pipes with copper pipe and rubber hose and not been able to connect them together. I connected together tempoarily to get running.

I am prety sure that there should be an inline filter on the chassis behind the drivers rear wheel, any idea of part number?, and would also like to replace copper and rubber pipes with the correct pipes from the tank to the filter and from the filter to the engine, again any ideas on part numbers?.

Lastly should there be another fuel filter in the engine bay before the pipes go on to the injector rails.?

Thanks in advance

To replace with 'proper' pipes you will need to drop the fuel tank, which can be a pain in the rear, then, unless the fuel pump is new, you will have to wrestle with rusted on unions, break the pump outlets, buy a new pump and then start again.

My suggestion is that you use what you have, the copper/rubber pipe is more than up to the job, however, as you point out there should be a fuel filter in the pressure line bolted to the chassis in front of the drivers side rear wheel, when I replaced all my pipe work I just got a standard push fit with clips filter off ebay, larger capacity than the stock rangie one and held it with a big jubilee through a plate I pop riveted to the underside of the floor. This was mainly due to the fuel filter bracket crumbling before my eyes when I went to remove the old filter.....

Thanks for the reply.

I am going to have to drop the tank anyway, as the rubber pipe that has been fitted coming out of the tank, is rather dubious to say the least.

So there is only the one in line filter, not one in the engine bay?

Thanks

Yep, just the one filter.

If it's a 3.9 there should be a hole in the boot floor to access the fuel pump. Chances are the screws are rusted though.

There's nothing wrong with copper pipe, on rally cars it's used in preference to the plastic pipe. If using plastic it MUST be flourinated pipe suitable for use with petrol.

Likewise the flexible hose, it must be petrol hose with a pressure rating. You can find lengths of it in Halfrods along with the correct fuel filter, which is far bigger than that fitted to the soft dash and far far cheaper.

There is only 1 filter on a standard car.

Whoops, yes, of course there is, I was forgetting having ali-floored the back of mine

Sparkling spanner to remove the screws.
