? on a FAST efi fuel pump # 30085 inlet fitting
I have a used FAST #30085 inline EFI fuel pump. The inlet side of the pump accepts a 5/8 male straight thread with an o-ring( I think) and has a barbed 5/16" at the other end. I'd like to go to a larger inlet but I can't find much info anywhere about 5/8 staight threads with a o-ring much less where to get one. Any ideas?
