Hi I have been parting out an 87 f250 and fixing up my 81 I have the two fuel tanks from the 87 and was thinking of adding them to my truck any ideas on how to plume the fill for them I want to hook the two front together so I will have 35 gal in the front and 35 for the back they will feed the engine at the same time when I have the switch on front both fronts feed and so on I'm just having trouble with the fill

 

There is not room for them is there? You have a front tank on one side, and the exhaust system on the other side. And the rear tank fits in the middle rear.

 

My exhaust dropped off right behind my door so I have the room for the front Tank
