About Fuel Rails

VW and Audi Fuel Rails generally become a flow bottleneck when Injector flow greater than 440cc is required. Designed for OEM fitment JBS Fuel Rails are machined from aluminum extrusions and then polished to a fine luster. The 1/2" i.d. fuel passage holds enough volume to eliminate fuel pressure fluctuations that will occur when running big Injectors on lesser rails. Ends are tapped with -6AN threads which can accept your choice of fittings. Mounting tabs are included for an easy installation with OEM hardware.

Use our precision-fabricated adaptors to fit OEM fuel pressure regulator for an inexpensive and OEM-clean set up.
