Fuel Inlet Upgrade for DS Pumps
DS4 injection pump 3/8" fuel supply upgrade. This replaces the restrictive factory 1/4" inlet fitting that screws into the regulator assembly and allows you to run a new, larger, fuel supply line directly to the injection pump.
Now featuring 100% aluminum construction! Our adapter fittings are milled from virgin aluminum stock, specifically for this application. Custom extended length for ease of installation, black anodized and laser etched!
Full-flow style for maximum performance and the hose barb is a push lock style. Does not require an unattractive hose clamp or expensive braided hoses for this low pressure system.
THIS IS THE FITTING AND O-RING ONLY. PUSHLOCK FITITNGS ARE NOW AVAILABLE IN SEPARATE LISTINGS SO YOU CAN BUILD YOUR SYSTEM HOW YOU WANT.
We recommend upgrading to an aftermarket spin-on style fuel filter and ditching the factory FFM to completely modernize your fuel system.
