I have a Racor filter/water separator installed as the primary filter, between the tank and the fuel pump. I have a late model A4 with a mechanical fuel pump.
I would like to install a secondary filter and I'm looking for suggestions on the type/brand and the location. I would think I need to place it between the pump and carb, but on my engine there at a short loop of copper tubing between the two. Putting a filter here requires either cutting the copper tube or changing the tube out and replacing the fittings. There is not much room between this side of the engine and the wall of the engine compartment.
It would be simpler to add it between the Racor and the pump. Is the vacuum produced by the pump sufficient to overcome the restriction of a 2nd filter?
Any suggestions are welcome.
thanks,
Dave
