Quick, stupid question from someone new to an electric fuel pump. I have the timing cover off my 340 to replace the gaskets, and I just put an electric fuel pump on the car, eliminating the mechanical pump. At this point, I no longer need the fuel pump eccentric and would like to remove it.

I know you can have cam walk if the bolt isn't tight enough, and the bolt does torque correctly without the eccentric, I just want to make sure that it won't cause a balance issue or if I need to add a washer or something similar to take up the thickness that the eccentric used to provide.

Thanks!
 
You need to have the proper cup type cam retaining washer on there. The cam gear is retained by clamp load. The key is only for orientation and is not intended to drive the camshaft! Summit sells a engine hardware kit by Dura-Bond that has the proper retainer. 65'
 
why not just leave it on?
what if you ever break down in hicktown USA and cant get a new electric pump?

i for one, would like to know that i am two bolts away from putting a mechanical pump back on and continuing my journey
 
Why the electric pump? Fuel injection?

I have the cup washer and it's on there. I just don't want to put the eccentric back on. The ultimate question is does the 1/8" or so thickness of the eccentric matter?

The car is a race car, it goes everywhere on a trailer. I'm over mechanical pumps. The plumbing is now set up for the electric pump.

No, still carbureted. Mechanical pumps that can produce enough fuel pressure for what I need are as expensive as an electric and still not as consistent. It's easier for me to manage an electric pump.
 
Yes, it does matter. There are 3 various depth cup retainers. You removed the eccentric and have the original retainer. 65
 
My son made a couple of these. One piece. I saw one laying in the garage I can take a measurement off of if needed
