I have heard that the kit for the 2000 will work on the Boxxer, just uses shorter length of the tubing. That tubing is thin-wall silicone rubber and not readily available. Thanks for finding those kits, I know a guy that needs one. Ron's has good inventory, nice. As for Slimline, let us know the story when you get them on the phone. I suspect they are re-grouping to launch the online store.
Not much here on the Sullivan pumps. I have 3 and only one is not leaking. Even that one leaked once, then it stopped leaking. I don't reccomend these !!
You're correct, the SL-2000 maintenance kit will work fine on the Boxxer. It is (as you stated) just a longer length of tubing and the o-ring for the top of the fuel jug. I'm not sure it's considred thin walled, but it is more pliable than something like Prather or the old Aerotrend blue fuel tubing. I've never been able to confim this, but I have a hunch the fuel tubing Slimline uses may come from Sullivan.
