Hello Cat man do,
Yes, I called you the other week when I learned that you had some 500EFI parts. But you asked $150 for the pump and I offered $50 as I only need the pump, not the pulley or hose. There is a new one on ebay for $99 plus freight. Let me know if you want to sell just the pump for $50 plus freight.
Thank you,

Velocity Tom

Hello Velocity Tom,
Thanks, I was told that Nappa has the same pump except that theirs does not have the stainless steel plate and the pump impeller is not bronze. But I have not been able to confirm this.

Hello RBeyer,
I checked the part numbers through Merc and they are different part number (500EFI pump is 811573A04, 454 Mag pump is 8504541). So I think they are different.
