Uh oh!! I might have some semi-bad news. The SLS pump consists of 2 halves, with a seal in the middle. That seal is NOT AVAILABLE!!!
Anywhere! The 3 you reference above are not the one I am referring to.
The pump I had on the
Flash leaked right in the middle of the 2 halves, so I disassembled it and tried everywhere, including dealerships to find the gasket. The dealer didn't show it in their system. It is a part of the pump, which of course is around $1200 bucks!
Some outstanding forum member sold me a pump for $50 bucks, and it worked like a charm. I can't remember who it was [sorry

], but they really did me a solid! They also pop up on ebay from time to time, and seem to go +/- in the $100 buck range, usually slightly less.
Make sure it isn't the hose or the crush washers at the pump.
