Ive seen people use the xj tank in an mj and mount it in the bed. It looks like an awesome mod considering ive smashed two tanks in two weeks. My only thought is that the fuel pressure will be too great for my carbed engine. Its a 2.8 v6 pos. Would an adjustable fuel pressure regulator mess with the stock xj pump? Like hold it back too much? Or if i found a carbed xj, could i use its tank and oumo without worry? I know its a very small amount of pressure for the carb but alot higher for fuel injection. Anyone that can help me out with this will receive a digital cookie and a thank you.
