Fuel Pumps; Dual Action , F Head

I finally unpacked a box of new parts I bought from Kaiser's. One thing I bought was a new dual action fuel pump to replace the glass bulb fuel only type installed.
What shocked me was the force required to activate the lever.
I called Mike at Kaiser and he didnt have a good answer, he didnt know what kind of load was needed.
Im concerned that its too much and will damage the camshaft.
Any thoughts?

Michael -
I replaced my broken glass bowl with the same type of pump and I remember thinking the same thing. I haven't put a lot of miles on it but so far so good. Just my 2 cents.

This is one of those areas I don't mind admitting I don't know much. Mine seems tight too. But I'm wondering if that is designed to keep the arm from "floating" when the cam is spinning at 3,000-4,000 rpms to make everything keep up with your gas peddle. If it didn't spring back with authority, it may start skipping and then you could loose your pump action.

Having put one back together recently I can say with fair confidence that the lever takes quite a force to push downwards. So I think you guys are alright.

You'll be fine with it. If it were loose, I'd worry.
Old fashioned service never goes out of style.
