Three fittings. Different orders depending on the year -- you probably got the wrong two of the three! You need to "restrict" the return line.
Should fit! if you bought the kit.<b>97 Camaro 3.8L M5</b><br />Car for sale<a href=\"http://terpmotors.com\" target=\"_blank\">terpmotors.com</a> Terrapin Motorsports! UMCP

ok i have been thinking about it, if i was to deliver fuel to an engine i would want the bigger of the two hoses and use the snaller one to rerout the excess fuel back to the tank so no matter where the fuel return line is it should be the smaller one of the two is that correct?<a href=\"http://www.cardomain.com/profile/blackfbird_98\" target=\"_blank\">http://www.cardomain.com/profile/blackfbird_98</a>

ok, i am getting a flash light and going out to look.
but...the fittings that came on the FMU should be correct. Just plug the 5/16 into the 5/16 and the 3/8 into the 3/8.
DOH! I replaced the stock fuel lines with custom fuel lines on my car when I installed the fmu and the F/P gauge...but...
the lower hose on the FMU is 5/16. this should plug into the fuel return line ON THE FUEL RAIL. the fuel return line on the fuel rail (stock) is 5/16 no matter it 's orientation on your engine or what the goofy rksport instructions say. The center fuel hose connects to the fuel line you just disconected from the fuel rail.
So your FMU should have come with one male and one female fitting.
