jeeps got 20yrs and 200k on OE pumps i'm not sweatin that. not reworking the vessel is all i want from this, 1 and done.
if i could find the right plastic tank i'd never even consider aluminum and house it in a steel can w/lid.
@toximus , since your here how tall was the inner box on that GR tank ? did it come up high enough to keep baffle balls or tubes off the pump assy? did it have room for the sending unit to function?
I've had to replace my pump once in my TJ and I only have 83K miles on it BUT may TJ has sat a lot which I'm sure wasn't good on the pump. Finding a tank that fits the stock pump/sending unit seems to be the bigger issue since GR & MB both make their fuel cells taller than needed.
I've still got to get under mine and measure to see how much room I have and if I could fit a GR tank.
I had to cut out the box for the TJ pump to fit in and for the sending arm to fit. It's roughly 4"x4"x1". Since the TJ pump has a built in sump I didn't see a purpose of keeping it anyway. Besides, I think a trap would work better than their maze if that's indeed a concern.
A baffle wall or two to slow sloshing on fast turns seems to be a decent benefit even if only to stiffen up the tank and stop fuel from hitting the sides so hard. But even then I'm not convinced it's necessary.
Anyway, I'm happy with how my cell turned out. That said, if you can fit it under the Jeep, it's easier and leaves more room inside for other stuff.
If a GR tank will fit then I agree it's a better idea than a fuel cell.
