We have successfully tested our fuel pump upgrade and have determined the final kit contents.

The Concept:
In essence the upgrade uses a roller cam follower in lieu of the stock prone-to-fail flat face follower . The advantages of the roller follower are long life and lower friction.

The Details:
In detail the new roller follower is larger in diameter than the original flat face follower. This requires a new mount bracket that houses the roller follower and mounts the fuel pump – see below.

Also, and most importantly, the cam profile is revised to achieve the right fuel pressure at the right time. Revising the cam profile is necessary because the lift of a roller follower versus a flat face follower isn’t the same. Simply put you can’t just swap a flat face follower for a roller follower and get the same lift. You have to revise the cam profile too. To the casual eye the new profile may look like the old, but when view side-by-side the difference is obvious.

The challenge with the upgrade kit was how to cost effectively revise the cam profile and modify the end cover. In the end we decided the proper way will be for customers to send us their intake cam and end cover which we in turn will install the revised cam profile and modify the end cover – all with same day turn around.

The Kit
The compete upgrade kit consists of a roller cam follower, a fuel pump mount bracket, a revised cam profile installed, modifying the end cover, longer fuel pump mount bolts, O-rings, new valve cover gasket, and new end cover gasket.

The price for the complete kit will be $425 but we have an introductory price of $335. Availability information is coming soon.
