I use an inline but I have 8 an lines from the tank to the HPFP. This one I think https://performancefuelingsolutions...10-orb-universal-billet-10-micron-fuel-filter
I use this guy http://injectordynamics.com/id-f750-fuel-filter/. "Use" as in I have it but car isn't running yet...
In tank plumbing is OEM.What are you using for driver to passenger gas transfer? What are your line setups like in tank?
In tank plumbing is OEM.
I have a Walbro 535 and 450 on hobbs through OEM line to the OEM regulator, then AN lines to fuel filer, Ethanol sensor, then splits to HPFP and PI, then from PI, to FPR back to the tank.
Ive bypassed it in the past, ran a new corrugated line from the top of the venturi system to barbed bulkhead fitting that i drilled and installed on the factory fuel tank hat instead of it running into the oem fuel filter and then i ran a aeromotive fuel filter in line underneath the car, did me well at 700 whp
Yes, correct. I did remove the little filter inside the HPFP but that is why I installed the extra inline.So you're running through the OEM filter and an additional filter?
Fresh fuel pressure regulator/filter was a big improvement on my car.
Out of curiosity I have opened up the filter and it was full with dirt etc.
Deff caused some restriction.
Oem replaced with intank surge tank and inline radium filter near footwell.What is everyone doing for their fuel filters? What are the limits of the oem filter? Mine might just be old, but I'm seeing fuel pressure drop at 20psi with a pair of 450hp pumps.

surge tank custom or someone making that?
Probably has this --> http://www.radiumauto.com/Fuel-Hanger-Surge-Tank-BMW-P1542.aspx
Terry bought a bunch for testing. Never used them and had them for sale $100 cheaper. They are all gone now I believe as they are backordered on his site (I has just going to pick one up finally).
Nice, if I still see any restriction with the stock feed line or filter, I may end up using that. Will keep the stock venturi in place then feed through that. Or I may just wait and see what PR comes out with.
