there are also a lot of laws/rules to follow in that case....so be careful.
I say this cuz when I put an aux tank in the bed of my dually, had it been for gas, it would have been illegal..but it was diesel.
And since you want to put it in the people space, it will be even more restrictive.
Why not just get a larger fuel tank ??
They do make 30+ gal fuel tanks for xj's. Sunset Fab and Genright just to name a few.
Larger tank would be better, but it's only about 10 gallons more and much more expensive than a fuel cell type thing.
Wouldn't pass smog in CA. You would fail visual and manual EVAP test. You can modify the Dorman one to hold 27 gallons. Part number: 576-656 currently on Amazon for $90 free shipping. Coupled with a 5 gallon Jerry can your at 32 gallons.
oh crap, missed that.But the OP has a '99 !
oh crap, missed that.
I believe he is aware. Also pretty sure those are the ONLY companies who offer larger tanks for the XJ. The Genright only being for 97+ and Sunset being of questionable build quality.
There are more than just those 2. Not only in the states......
