What size fittings screw into the s-fmu. For some reason I got whatever screws into it, and the other end is AN -10. Is this normal, I thought they are supposed to come with AN -6. Also can I find a fitting that will screw directly into the s-fmu and have a hose barb on the other end. I bought socketless hose fittings, in AN -6 female to hose barb, but they didn't fit the s-fmu fittings. I would appreciate any help. Also I know it has been asked but I'm running 5/16 hose all the way around pretty much, anyone see a problem with it? Thanks.

incase anyone wants to know, I found a place that has AN -4 female to AN -6 male, www.pitstopusa.com they have a lot of stuff actually, and the prices are not too bad.

The SFUM should have come with 6an fittings. To change them buy a set of 6an unions and swap over the o-rngs. 5/16 is only good for a return line, if you are gong to be adding a turbo with larger injectors better go with 3/8 which is 6an.
