in the process of 12v swapping my 1995 v10. was hoping to keep the v10 fuel lines and tank. i know the v10 has a fuel pump in tank. what did the 12v have?

12 valve has camshaft-driven lift pump on side of block 

whats inside the tank? is it just the v10 shell without a pump. a hose to connect top of sending unit to bottom strainer thing?

Tank should be fine, it's the filter neck. Too small to fit diesel nozzle in the hole. And if it was me, I'd up size the lines to at least 3/8.

Open it up and look in it. I have seen some pretty nasty looking old fuel modules on here. Might need to be replaced anyway. My 96 eas a V10 but I never had to open it up.

thanks for the replies. i have the parts truck there with the diesel fuel tank in it but the truck level with the hood with snow. are the diesel fuel lines the same size as gasser? (3/8 fuel, 5/16 return i think)

i might just swap sending units, i will probably have to drop the tank to get the filler neck off the diesel anyhow. see how it works out i guess

The parts lookup manual on this site here would benefit you greatly.  Not sure where it is on this site but it came in very handy for me when getting a new to me tank for my 01.  I ended up I think with a 96 tank and the threads were a little bit different at the top for the gas cap and I believe it was a vented or non-vented had to change the fuel cap.  The fuel modules interchange pretty easily, as far as threads at the top.  The actual size of the draw straw might make a big difference so I just put a bulkhead fitting in, 1/2 inch I believe.  A fuel module in the parts lookup tool is chapter 14, if I remember right.

Now would be a good time to upgrade your fuel system, I would not use factory lines they are too restrictive. At least a 3/8 supply and return, most of us went to half inch. The only one that stays factory is a return from vp44 and back side of the head where it meets into a T and back to tank. 

Does a 12v need that kind of an upgrade?

When I had my 12v I ran a 3/8 all throughout, part of reason lines were leaking and no fuel gauge, so I modified the fuel module too while at it. 

Does a stock 12v need bigger lines, probably not nether does a 24v. But if you're changing lines might as well, doesn't cost much more for piece of mind. 

I guess to PO if lines are fine and no mods/power increase on engine then should be able to reuse v10 lines, 

I am currently using a 5.2 tank on my 24v.  Had to use my diesel lid or top but the rest of it is the same.
