What fuel filter is everybody runnning?
I am running into fuel pressure drop , I think I have traced it back to the filter. I removed the stock filter and stock location. I put a BMW filter in it place. I dont think this filter can handle the high PSI of a turbo car?

I moved my stock filter and attached it to the bolt on the gas tank hold down strap right behind the differential. Now it is super easy to replace .
When I did this my 0 boost pressure went up 2 psi, 38psi to 40 psi. Do not know if this was due to a cleaner filter or new location with bigger hoses.

Here is a look at what I had to do to get enough flow using 2 pumps and how to filter it, Originally I was going to use one mallory external pump, I don't know what it is with all the manafactures of large volume efi pumps, but no one had any in stock, and it was a 6 week wait on just about any pump I inquired about, so for the time being I am going to run 2 walbros. One internally, One externally..
I sumped the tank for an external pump.
Since I have to Y block the system somewhere I decided to go with this filter that will accept two pumps in, and has two feeds out , it flows about 500 lph and is rated to 100 psi for fuel injection, price was good to...

I run a large Bosch filter made for a 80's Audi with the mechanical FI. This filter is good for a couple reasons. The mechanical FI needs clean fuel to work properly so it keeps the fuel clean and it's a big filter to keep the pressure drop low.

I use the NIPPODENSO upgraded pump with stock regulator for my 550/1200 combo.
You can get better pressure/fuel flow by running a heavier gauge wire from the
FP resistor back to the FP. The stock wire drops too much voltage do to it's resistance.

I used to have a K&N stainless steel filter, which was very restrictive, I had to jack up the injector pulsewidth to compensate. Go with Aeromotive filter, which has less than .15psi drop at 200 GPH. As soon as I switched to it, I had to turn the fuel injector pulsewidth way down. I'm running the NipponDenso pump as well, with no issues (stock wiring, 402 rwhp at 13-14 psi)

My relocation:
Removed the metal tube between the tank outlet and the filter, and replaced with hose. Used a longer hose from the filter to the tube going to the engine.

Most people I know run Aeromotive filters and they haven't experienced any problem with them, infact they work good. I still haven't decided on what filter to go with, but mostly likely it will be an aeromotive filter.
