fuel filter position
Running 1.8 zetec with fuel injection mounted the injection fuel pump low down i.e level with the fuel tank outlet.What i need to know the fuel filter
that is going to be fitted down stream of the pump is it ok to fit this at say at a height level with the top of fuel tank.Would this have any adverse
effect.

Your injection pump should have a maximum lifting spec.
Should be fine.
Out of interest, why are you using a post-pump filter? I've used pre-filters on both my lift and injection pumps.

I always fit my filters before the pump... Its stops the crap in the tank from wearing out your nice expensive pump.
I usually have one before the pump, and one just before the carb / injectors... A Bit overkill I know.
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.

Thanks for the advice . Im putting the filter after the pump as talked about in previous filter threads. Seem pumps dont like sucking thro filters?
Also when i have replaced metal encased filters on tin tops they seem to be in the engine side of fuel pump.

The Mazda filter system (as on the MX5) is a low pressure filter, in the tank, and then a high pressure filter after the injection pump but before the
injectors.
Mounting the high pressure filter higher than the pump is probably fine but check the pump spec' - as Steve said.

Ive gone for one either side too, a low pressure one to stop crap getting into the pump from the tank, and a high pressure one to prevent the
injectors being screwed if the pump decided to start breaking up and sending its own crap down the fuel line.

Second that vote for pre and post pump filters. I've recently checked my pre pump filter and found plenty of rubbish which would have jammed the
pump. The cost of a post pump filter is a few quid and saves any hassle if something does get into the injector feed.

So long as your pump is gravity fed (i.e. lower than the tank) then you shouldn't have any problems with a pre-pump filter.
