I was told the supply voltage to our stock pumps at full demand is 12.8VDC, due to the FSCM (or whatever it's called), whereas I think the AEM pumps are rated at 13.5VDC.

The output, as you know, increases significantly as you increase the voltage, so it would make sense that the AEM pump output would be less than advertised if the supply voltage wasn't as high as what they are using for their tests.

Ohh gotcha. From what I could collect from the other threads about this. There are still folks seeing issues with pressure drop on these pumps even @ 18 volts through the new FPCM unlock (whatever you want to call it). So voltage is taken care of, it's now either coming down to; Pump actual ability, and restrictions out of the pump housing/module (the neck he found @ .22").

Ok so I tested the fitting change with the aem pumps intank and the bap all set the same as the before logs and I picked up 4 psi at 85% duty cycle on id1000 injectors it maintained 65 psi vs 61 psi before not to bad for just changing out a fitting

Nice! How much do you want to charge to have my bucket mailed to you and returned with the pumps and fitting changed :p

Are you running E too?
 
What kind of pulley combo? Is this with the Jokerz stage 5 blower?

Did you consider drilling the fitting from both sides with a 1/4" bit, rather than replacing it all?

I tried doing this on a spare pump assy and the plastic got very thin. This is the fitting that many owners have reported slow fuel leaks from...

So with this small Upgrade, what do you think the power potenial is with E-85 now, given enough injector........750ish WHP
It gave me about 10% more fuel over aem pumps with a bap. So I'd say 10% over anything you currently have

Can you post the part numbers for your elbow and fittings?

Just in case I need to reference this in the future!

4psi from the 90 degree elbow is decent.
