Product details

HEL Performance's adapters and fittings route fuel, oil and water lines across a wide range of motorsport and automotive uses, in systems that must withstand high pressure, demanding conditions and extreme heat. Components - spanning stainless steel bleed nipples through to aluminium hose ends - are CNC-machined from premium materials, giving strong resistance to corrosion and wear.

Sizes run from AN03 (AN3, -3) to AN20 (-20), covering precise flow-rate and pressure tuning.

This EFI push-on quick-connect adapter turns an OEM fuel-injection line, or a fuel rail port of the same type, into an AN male thread - opening the door to fittings, braided steel hose and aftermarket fuel parts.

Fittings and adapters are made from 6061-T6 aluminium and finished in a hard-wearing black anodised coating.
