Reply to "Holley Mechanical Fuel Pump Install"

1. Use a Breaker Bar with an extension and Socket at the Damper Bolt. Turn the engine over Clockwise!! So as NOT to Loosen the Bolt!
2. The 'Excentric' is a stamped steel 'Cam' the rides on the face of the Camshaft Sproket, at the front of the Camshaft. It actuates the Fuel Pump ARM!
3. By 'Trial and Error' when inserting the Pump into position. Unless you can see in 'there' with a Flashlite and a 'Inspection Mirror'.
4. There is Only ONE Correct way It can be Installed!
5. I recommend using the proper 'Paper/Cardboard' Gasket with a sealer on both sides (such as Permetex or an RTV). After cleaning all contact surfaces with Lacquer Thinner! Very Oily down there for JUST a Sealer!
6. With whatever Pump You go with; it is always recommended that a 'Moly-Lube' be put onto the Arm Contact Surface of Any NEW pump to aid in Breaking-In!
