I am running the Cartech FPR and want to install a SFMU. I've done some searching on this and it seems I only need to get 6an - 4an reducers to install (I need 3 right?). Is this all I need. I have to order the fittings online and want to make sure I have the correct item(s).

if i remember correct on my super fmu it came with 6an fittings. you can order 4an fittings from vortex direct. i think you want to hook up fuel lines to these an fittings right? so really what you need is 2 '6an fittings' with whatever size hose barb for your fuel lines you need. for example if you got a 5/16 fuel hose from the cartech to the fuel rail you would want that hose barb for that 6an fitting.
hope this helps a little.

thanks man that helps A LOT. I've never worked with fuel systems before so I was really lost on finding the fittings I need. Especially because every auto shop I went to had no clue what AN fittings were :shrug

auto shops like napa and autoazone don't carry that. you gotta order thsoe online or like i did, i went to a dedicated speed shop (they specialized in V8 but V8 use those too).

yea my sfmu had 6an fittings. Isn't it funny though when you go to places like napa and autozone where there trying to help you and they have no fuckin idea what a sfmu is and why we're trying to take off our fpr's. I just wen't to jeg's for my an fittings after going to all auto parts stores in town.
