After much frustration with weeping OEM lines, we invested in a BMRS hydraulic hose crimper and the corresponding hose & fittings to make our own! The line used is their Smoothbore PTFE with stainless over braid which is rated to 3000psi service pressure. The hose end fittings and crimp ferrules are 304 stainless. When assembling the hoses, we go the extra mile and install a thermal and abrasion resistant sleeve over the braided portion of the hose.
The two distribution block to turbocharger lines are 3AN sized and the engine to distribution block is 4AN. New copper crush washers are included for all banjo fittings.
Before installation, use brake clean and compressed air to ensure the insides of the lines are 100% clean.
