This is the Dregs’ Diesel Fuel Line Builder Kit for the 6.9 and 7.3 idi engines running the factory mechanical lift pump to build your own rubber line to the fuel filter housing and a rubber fuel line to the fuel injection pump.

This is all the fittings you need, just supply your own 3/8” hose.

This fixes the factory flawed rubber compression fitting that uses a rubber compression seal that will crack and suck air into your fuel system making for hard starting with long cranking times before starting.

This steel compression fitting will come ready to install with Blue Monster Teflon tape.

*fittings are designed for rubber braided fuel line to be pushed on and lock in place, No Hose Clamps needed!
