i'm bumpin this yr old thread to rant a little..........
the TJ pump (at least mine) is maxed out at the 12" mark, it goes no further, and actually requires a little bit of pull to hold it down at 12". i'm hoping a full body of fuel will weight it down.
1 might assume GR knows a little something .......so why are they intentionally hanging the pumps over an inch off the bottom? but it is the only "TJ" cell i can find with a fuel trap around the pump assy.
MB is right at the 12" limit but, it's a slosh box with no trap at the pump, so at a 1/4 or less tank you could tip it and begin starve the fuel sys if your sitting there for more than that wet fuel sock/filter holds.
RCI and Summit make a tank with a trap for universal use with an internal pump assy., but it appears to not be constructed/configured in a way that leaves no room to place the large flat ring needed to hold the TJ pump assy., it's made for a small headed universal pump assy.
so in reality nobody makes a cell for a TJ OE pump that's built right. they are either the wrong depth or they have no fuel trap and none have any built in slosh control.
i really need to learn tig............i might try something like this.
perforated baffle walls to keep slosh down, tapered design to keep fuel at the pump, it would take a sufficient platform type mount to support correctly but could be done. (excuse the chicken scratch notes , it's hard to write with a mouse.)
i'm gonna snag a 15gl rectangle from Summit, 30Lx9Wx12H, this should just work with a flat ring. it's the same rectangle as the MB. just 40$ less and close enough i can have it today. i'll fill both ends with foam and try and fit my baffles on either side of the pump assy to keep the foam trapped at the ends and the pump area free for the dam sending unit to function.
i also considered getting the 15gl 30Lx12Wx9H and having a custom job done to fit an 6-8" dia. x 2" deep cup onto the bottom, so the pump has a nice bowl trap to sit in.
