I'm putting a Stealth Ram in my '68 RS and have already installed new steel hard lines from the back of the car to the front. The fuel rails are -6 on both supply and return. Here's my question -

I've used 3/8" hard line for the supply and 5/16" for the return. I know I can get a hard line adapter to go from 3/8" to AN so that's easy. What about the 5/16" line. I've not found an adapter to do that. Have I snookered myself by using 5/16" return line? Any suggestions?



Also, can ya'll recommend a good source for the required AN fittings?
