I have FE parts for sale that I can trade or willing to buy any kits you may not be using. Look in the all parts for sale. 1959 Lincoln 430 MEL. Car build was November / early December 58. has an A/C fuel pump. Water pump starts with 575. Ask for any other needed info.
Thanks

I got my fuel pump kits from Then and Now. Seems to be high quality stuff.

The 575 water pump would likely be a 1959 and have the larger diameter shaft. The early 1958 pumps were unique and had a smaller shaft. I'm not sure who supplies kits.

I wonder if a FE kit would work. I have both types to compare. Thanks for the link. It looks like my pump diaphragm was replaced with a piece of tire tube. Unless the tube was petroleum proof it wouldn't work for long.
