I've got an EXCELLENT condition Accusump 2-quart unit for sale. The Accusump includes a pressure gauge, electric valve, and t-bolt mounts. I'll include the hoses that I used with fittings, but you'll likely want to go bigger as my original hoses were larger. There is approximately 16,000 mile on this unit.
I also have a sandwich fitting for this too.
I can get new pictures of it removed if interested.
$250(
OBO) + Shipping for the 2-quart Accusump, gauge, electric valve, mounting brackets, and sandwich.
