TracTuff DIY J Series RWD Water Pump Inlet

Description

When I made the M28 to -16 port adapters, I had no plans on making something to hold the water pump’s inlet tube; I figured the end-user would get creative and come up with something. After months of requests, I decided to dive into the issue and devise a solution.

The DIY kit includes everything you need to create a water pump inlet. A block bushing that has a machined shoulder that stops against the block, 1-1/4″ counter-bore to receive the 1-1/4″ u-bend, and an o-ring groove to accept the OEM crossover tube o-ring. The u-bend is 1-1/4″ on a 2.00″ CLR. The billet triangle has a 1.290″ bore, allowing for some misalignment, as well as slotted mounting holes, which give additional flexibility with misalignment, as well as accommodate engines that may have had cylinder head or block work done that affects the deck height.

NOTE: I recommend cutting 6.00″ off of one u-bend leg and 2.50″ off the other as a starting point. When inserting the shorter leg into the block bushing, you may find that you need to force the bend down, essentially cheating the bend in order to get it to line up with the billet triangle plate. This will help when you remove it to weld… it will stay in place as long as you don’t handle it roughly! Be sure to leave the o-ring off until you are finished.
