Larger Fuel Tank for 1/2 TON long body??? Help

[Bismarck2]

You know They did come with 8.1L as an option still. Thats great to know that they at least had the 37.9 Gallon. Now I all I have to do is figure out if the fitment is a drop in or is it a major project.

I have not been able to find any aftermarket options. I think that it should drop in, I cannot see why it would not God knows I have been wrong before though.

I guess I need to find a mechanic who really knows these cars well before I drop the money to buy the tank.

Does anye know any good shops that would the 3/4 ton vs 1/2 ton differences really well?

Thanks to everyone.

Go into the shop at your local dealership and ask one of the techs if they know. They see a majority of these vehicles so maybe they know if there is a difference in fitment between the tanks.

Thanks, Yes I Wthink I will do that. I should probably clal first. I am just affraid it will be one of those little things that will turn up to be a deal killer. I think I also have the Fuel Pump. Then I wonder if the fuel lines are all the same or if the larger tank has some different return line, etc...

I guess it would help if the tech worked on both of them, but the dealerships never let you talk to the mechanics and usually its a service advisor who does not know anything :-)
