k, im going to be installing my smfu and walbro 255. the Smfu came with blue fittings on the bottom and side, i am assuming thos are 4 AN? i go from the side fitting of smfu to my test port on the fuel rail correct? and that will be 4 AN SS line correct? T'd with a gauge probably. now, im gunna run #30 injectors and i saw on posts where i should run a SS 6 AN as my return fuel line, if i do that will i need new fittings for the 255 fuel pump and the smfu? and will 10 ft be long enuf to run the return line? and where would i procure SS line at a resonable cost?
also, are the walbro 255 fuel pumps universal? (im hunting on ebay)
TIA

The fittings that come on the sfmu are 6an

10ft of 6an will be enough for the return line depending on where you mount it. I have my sfmu mounted on the passenger side of the firewall and I probably had about 1ft left over that I configured someway so it wouldn't hang down and I wouldn't have to cut it.

You won't need any new fittings for the fuel pump, if you haven't yet installed it, the only thing you have to do is drill a hole in the bracket that holds the stock fuel pump in place because the walbro is a bit longer. See gsgoinfast's write-up if you want pictures.

Just get a walbro 255 for any 2g eclipse, will probably be advertised as for a gst/x

You will probably want 4an line from the fuel rail and then get a fitting to go from 4an to 6an to screw onto the 6an fitting on the side port of your sfmu

you can get the ss line from summit

you can use this diagram for part #'s
http://www.2gnt.com/index.php?d=SFMU%20Installation%20Diagram

the part numbers there are for 4an line

10 ft of 6an ss part number - aer-fca0610

3 ft of 4an ss part number - AER-FCA0403 <---that should be plenty for fuel rail to sfmu

Fitting you'll need for 6an line to connect to sfmu part number - ear-300106erl

as you can see in the diagram, vortech has the adapter assembly for 4an lines, but it's just two fittings and you'll only need one of them if you run a 6an return line and its about $20 shipped from vortech, so if you can find the fitting you need from summit you'll be better off. If you're not exactly sure, then it's probably better to spend the money at vortech, the one fitting alone is probably gonna cost 6-8 bucks anyways so you're not going to spend much more at vortech and you'll know you're getting the right part

kool thanx!

Great write-up. You should really really put this in the Main Page wiki so that in the future we can just point ppl to it instead of have to yell search or write out instructions the 1,320 times a week we get asked this question. good job on it.

I wouldn't buy a Walbro from eBay anymore since there are imitation ones now (eBay I believe made a bulletin about it).

Go to extremepsi.com to get it. That's where I just got mine from, 102 shipped.

Maybe if I get a little free time tomorrow....

I don't know why, but I feel honored getting a compliment from DJ, lol
