Protomotive Fuel Return to 6AN Adapter for 996 Turbo

What are they for?

  • When upgrading your fuel system the Fuel Return to 6AN Adapter for 996 Turbo will make a 6AN return line a snap!
  • These will slide right into the oem return line fitting on the engine and provide a 6AN male fitting for you to connect to.
  • This will help improve the flow of your fuel system when upgrading to high flow fuel pumps like the Protomotive Single Walbro 450 drop in, or Protomotive Dual Walbro 450 fuel pump upgrade.
  • This is for a 6AN upgrade to the chassis side return line while maintaining the OEM engine side return line.

Can I do this myself?

  • Sure you can!  This makes it easy for you 🙂
  • If you need help with the rest of the fuel system, AN fittings, or lines, just ask.
  • We stock a lot of these to build our complete fuel systems and may have exactly what you need!

What are they made of?

  • These are CNC machined out of billet 304 Stainless steel for a long lasting upgrade.
  • The tab is also 304 SS.
  • The E-Clip is a black oxide coated 1/2″ sized clip.

How can I check for leaks?

  • With the engine still in the car, and all of your fuel system connected you can either use a Durametric cable or Piwis to activate the fuel pump.
  • You can also quickly crank the engine over to build some pressure then check the fitting for any drips or smell of fuel.
  • The return line has very little to no pressure on it, so it won’t spray like the pressure side would when the pumps are on and running.
  • With the engine out of the car, connect the Fuel Return to 6AN adapter fitting for 996 turbo to the return fuel line and put a bolt through the tab to hold it in place.
  • Place a 6AN cap on the male 6AN fitting, then pressurize the fuel system at the inlet fitting with an air line.
  • Spray some soapy water on the fitting to be sure there’s no bubbles.
  • If there are replace your O-rings, apply some white lithium grease and try it again.

Can I watch a video explaining some of this?
