Typically I like to figure this kinda thing out on my own as I know it is a bit of guesswork without being able to look at the actual car, but the car is 6 hours away and I have limited time to work on it. I am looking to overhaul the fuel system from the tank to filter. The car is a '71 911T with a '88 3.2. It runs great with no leaks however I have a replacement tank, would like to replace the old noisy pump, and relocate the pump from the rear to the front near the tank.


Current routing is as follows:

'71 tank -> 10mm hose -> 10mm metal tunnel line -> 10mm hose -> old bosch pump -> ~5/16in hose -> ~5/16in hard line -> 5/16in hose -> fuel filter

Proposed routing:

SC tank -> ??in hose -> in line fuel pump (Bosch BOSCH 69458) -> AN-6 hose -> ?? metal tunnel line -> AN-6 hose -> 3/8? hard line-> AN-6 hose -> fuel filter


So the questions are:

SC tank outlet size (looks like the pump inlet is 1/2in) and inlet threads?

Best to use a metric banjo to AN from the pump outlet or is there a better option?

Should I replace the hard line that runs from the drivers side wheel area into the engine bay with 3/8in to keep it consistent (currently roughly 5/16in)?

Fuel filter ('88 3.2 filter PN 928-110-253-06-M67) inlet threads so I can replace the current adapter with one to fit the AN fitting.

Applying fittings to the body lines. Is it possible to replace the hard lines from the front with the tank, steering rack, etc removed? Would be much easier for me to use 3/8in tube and would know exactly what I have. My preferred option is replacing both supply/return with 3/8in tube with AN flared fittings.
