Side mount Gas tanks
« on: April 10, 2011, 09:15:42 pm »
Can anybody tell me the difference between the 73-86' fuel tanks and the 87' tanks for TBI trucks?

     I'm not positive, but I know the sending units will be different, someone like capt. or vile could answer your question directly, if they don't see this in a couple of days pm them and make sure your in box is not full.  ( they kinda get irritated when you ask and they can not reply )

I believe they have baffels in them also to prevent splashing around of fuel.  I could be wrong though.

You can use the tank.  Some on here have recommended just keeping the fuel level from getting too low as the tank will not have a fuel baffle in it like the '87.  The tanks from a SWB and a LWB are different sizes, though.

They have a baffle but you can run it without.
