Alright guys, got handled I think. It screws right into an o2 bung so from that I deducted that it was 18 x 1.5 thread. Neither Orielly or AutoZone could get anything over 14mm so I stopped by Bumper to Bumper and they had a non magnetic on hand and ordered me a magnetic one for $5.50 .
Had to order the other fuel filter anyway. Wix 33421 , $5 cheaper than ordering it from Oreilly and AZ couldn't even order it
So under $30 for both. Not bad.
