I am using the AEROMOTIVE filter with the 10 micron stainless steel element . What turbo and porting are you running (sub-Zero) ?.

crispeed

The 10 micron filter will not work before the pump.

It's too restrictive according to Aeromotive and also after finding out the hard way! You need to use the 100 micron filter before the pump and the 10 micron after the pump. The 10 micron gets clooged too easily making it useless before the pump.

Fuel pumps (any kind of pump for that matter) do not take well to restriction on the suction side, do what crispeed said.

93 R1

Sounds like a good start

OK I checked it back and found that I have the 100 micron ,stainless steel mesh filter on the suction of the pump .I havn't pulled it yet to see if its clogged though but I doubt it , but a while ago I posted something similar to this that had been happening to a local racer . He was using an SX pump and four 1600cc injectors and was running out of fuel up top (90% duty cycle) , He eventually put a SUPRA pump in-tank and "T -eed" it into the discharge of the SX pump , this solved all his problems !! , I think I'll try that before putting out for the twin 044 pumps, although the BOSCH set-up would be better , the other set-up would be cheaper.

I am using an HKS EVC 111 , boost controller and I'm having a hard time getting "it UP" , (the boost that is ) in the manual mode , I still haven"t programmed it yet in auto , the lower I go with the offset the less boost I get , am I missing something ?.
