@chines1 I was hoping you'd chime in! Yeah, I found a 10u EFI rated post pump filter, but it has -6AN fittings and max PSI rating of 60PSI. I wonder if that Pierburg pump really outputs 94PSI. That seems insane and would make pairing it with a 10u filter all the more difficult.
@chines1 can you explain or point out what you mean with photos by "Your clamped fittings are all high pressure socketless and the clamp is a back-up, nothing wrong with them"? All the fittings between filters and pump appear to be barbed and using those worm screw clamps.
Was just saying that the AN fitting on the pressure side of the pump is a socketless (made as a push on not requiring a hose clamp, however I am not comfortable with that so we add a clamp... fail safe. Yours cad a clamp and although not high tension it should be fine. Your clamps before the pump, off the tank and at the pre-filter, are all on the gravity fed side and also adequate as they are not under pressure.
