I have a STT fuel rail, with 1/4 pipe thread inputs, so i want to get slightly larger lines ran (from FP to rail), both in and return. i grabbed a spare hanggar, and bored it out. now since the fuel rail pipe thread is only 1/4", should i go with 6 an line? the options for the hanggar are: using a 1/4" mpt by 3/8 nipple. or should i use a 3/8 mpt /1/2" nipple? either way they are both larger then stock.. see pictures.

heres with the 3/8 npt 1/4 nipple

this would come thru more, and id mate it with an npt to AN fitting, would that work? id imagine id need some sort of seal or washer between there?

heres the idea in paint.. id do the same for the return line...and other ideas or objections?


im running the wally 255, would like to run 6an feed to my rail and 1000cc injectors (this will be for the 2.4)

good idea...
