I run two manual pumps. People run auto's and have no problem but I have always run into problems with auto bilges and it gets tight to fit them in an SJ. I usually flip mine on when I go out and then leave them on for the whole ride, they are fine to run dry.
I just wish the old attwood v500's were still being made. The one I have left blows my rule's away.
RULE MATE auto is better, plus you don't need to buy a switch.

any reasons why? besides fit?
Rulemate is...
1. More reliable.
2. Doesn't drain battery as much
3. Always ready and always on (if tied to a dock or whatever)
4. Less expensive
5. Easier install
I just run my manual rule 500 on the whole time I ride ans then flip it off when im done... No problems yet.
Were did you fit the rule mate 750? I have one siting here but having a hard time finding a good spot for it.
