Pre-Injection Pump Filter

I'd like to protect my new pump from bits in the tank/fuel by inserting a filter inbetween the tank and the pump. So far I've discovered:

-Someone on this forum recommended a Metro 16V filter (M18 thread). However the motor factor I spoke to tried 3 catalogues all of which gave a part number for a smaller bore part (around M14-16 I think) - anyone have a part no. for the M18 threaded filter?

-Someone also mentioned a little mk1 Golf carb filter but I'm surprised this flows enough fuel under full-load?

-Demon Tweaks said the FSE Pro-fuel filter would do the job (~?10) but I called FSE and they said no way for Bosch K-Jet. They recommend the bullet filter which is ?50+

Any other tried & tested solutions?

Thanks  :y:

Might be cheaper in long run to clean the tank out and just replace the main fuel filter [to protect the metering head] annually .

Not a lot of room between the tank and pump .

Looks like a lot of engineering for a four cyclinder 30 mpg road car - but the thought process is rock solid.  I have a new fuel pump, accumulator and metering head filter waiting to go into my ride & I am on the same thought lines as you - a filter between the tank & the pump.

I'll have a look tonight to see how this could be mounted without any gubbins hanging around under the vehicle - a bullet filter looks a bit like an over-engineered solution to me though at first flush.

Some pumps already have a tiny little mesh filter in the intake anyway - why not simply use one of these if not there already?

In any case, I think its a case of there's a lot of dirt and rust in the fuel tank because its 25 years old, not because it builds up quickly. So once its clean, I reckon you have a long time of trouble-free operation.

Do the mesh filters have a VW part no? I've not seen one before.

Cheers

The small filter on the input to the pump is not a VW part. I know for a fact that the pierburg replacement for the pump has this filter inplace.
 On late cabbys there is a small filter box(533201511A), i've always had one of these on my cabby and i've still had a pump fail. Since that happend I did full tank flush and no problems.
