Yeah your pre pump filter needs to be very free flowing so high micron, and you want a good size feed hose.
After I run a Bosch filter with AN 6 ends that’s 8 Micron

I only have one filter in line before the pump. After one of the high micron smaller filters plugged up on the first test drive, Steve replaced it with a regular Bosch oil filter. He said the 356’s were like that. I haven’t looked at it since. I love the vintage hotrod spirit.

Haha, EFi 356 with oil filter plumbed into the fuel system. Ferdinand has just pissed himself laughing in his grave  ;D :D ;D
The internet is a treasure chest of useful information.
