Raceonly FD 13B Billet Primary Fuel Rail


This 13B Primary Fuel rail was designed to provide one of the highest flowing rails on the market while also providing extreme flexibility in terms of fitment with various intakes. We have tested these with ALL Projay intakes and they will clear with a 34MM Injector.

This rail also provides the capbility to run a 60MM Injector in the primary rail while still being able to clear the secondary rail. While there are many quality rails available on the market, our main with this rail was to make one design FIT ALL. It will require no grinding or any modification whatsoever, it is designed to be a BOLT ON item for the CAST 20B and most Billet 20B configurations.

As always they are machined from 6061 Aluminium and all our designs are very well vetted before being brought to the market. You can be confident our product will fit the first time.
