HOW TO: adaptor your fuel lines to AN fittings

Recommended Posts

There are a few vendors out there charging around $140 for this mod. It really chapped my 4$$ as I knew the parts were probably worth $50. In addition, one vendor is telling people to cut a fuel line... :banghead:

 

Anywho, this is the method to convert the factory fuel lines to -6 AN fittings so you can use aftermarket rails. All in all this mod will cost around $50, depending on pricing at your local autoparts store, and where you get a short length of -6 AN line to connect the two rails in front.

 

Parts list:

3/8" x 4 3/4" Quick Disconnect "sending unit repair line (NAPA 730-4938)

5/16" x 4 3/4" Quick Disconnect "sending unit repair line (NAPA 730-4937)

3/8 tube to Female -6 AN adaptor (EARLS 165106ERL)

5/16 tube to Female -6 AN adaptor (EARLS 165156ERL)

 

Tools needed:

Mini Tubing cutter (NAPA service tools 2107)

(2) -6 AN line wrenches

 

And away we go...

 

Quick Disconnects:

Take the QD and cut it close to the bend:

Once it's cut, unscrew the red end of the Earl's adaptor, and remove the little brass ring inside. Slide the red end on to the QD pipe, and the place the brass ring inside (orientation doesn't matter). Making sure to keep the assembly towards the end of the pipe, thread the blue end into the red end (pinching the brass ring between them) and tighten using the AN wrenchs. Be careful not to over-tighten!

Repeat for the other tube.

Once both adaptors are built, slide the quick disconnects into the factory recievers and viola:

Once the intake is installed, connect the feed line to the end of one fuel rail (I chose the passenger side) and the return line to the return port from your FPR. A single -6 AN line is required to act as the cross over line between the front of the two rails. I will update this with pics of these last steps as the pics become available.

 

Special thanks to Slowhawk at Dez racing for helping me with the name of the quick disconnect tubes ;)

Sorry some of the pics suck -- huge humidity today, too much for the camera it seems.
