Mazdaspeed 3/6 Gravedigger Returnless Fuel Line Kit

Regular price $149.99 USD
Regular price $179.99 USD Sale price $149.99 USD

On this page you’re looking at the fuel line kit made by us in house here at Graveyard! Some people look to piece together their own fuel systems, but don’t have the necessary tools to make and assemble their fuel lines. We have gone ahead and taken care of that for our customers.


We use high quality PTFE Line, which has a lifetime use for pump gas, and E85! 

Included is the following:

  • 2 x 5/16 Quick Connect Fittings
  • 2 x -6AN to -6ORB Fittings (JMF/CS/Damond Rails)
  • 1 x Rail to HPFP Line
  • 1 x Factory Line to Fuel Rail Line

If you are going to run a CPE Havoc, you will need a -8ORB fitting which we can substitute at no additional cost. 

Email for any question you may have.
