I'm in the process of building an AP1 FI motor and I'm looking for advise/directions for the return line. If tapping the girdle what do you do, drill a hole straight through the girdle in between the mains and tap it with an AN fitting?
Same with the pan? Clue me in.

Thanks

 

Yes drill a hole on the girdle then thread it.
The trick is getting a small enough drill bit to squeeze in there to drill straight thru

Here this will help clear some questions.. https://www.s2ki.com/forums/index.php?showt...&#entry10315508
