Other than the filler neck is there any difference between the gas and dieseltanks? I am thinking of getting this tank. Are there any other aftermarket tanks?

Hey I thinkl you will be okay. Jus make sure your fuel pump fits the way it should. May I ask Y you need that extra weight?

 

Not so much worried about weight (150lbs) just like longer driving range. I get about 12 mpg right now with the 5.2 for approximately 400 miles before fill up. with gas at 3.75 (and going higher) would like to extend the dollar a little more.
