I will be starting my Cummins swap hopefully next month. Its a 97 Ford f250hd with a 5.8. Swapping in a 89 Cummins. The only thing i did not realize when I started planning for this swap was how the fuel tanks switched. On all the older Ford trucks I had there was a selector valve on the frame. On this truck there is not. I guess it switches tanks with the in tank fuel pumps. My question is can I run the Cummins with the electric in tank pumps instead of the mechanical pump? Will the gas pumps work with diesel fuel? Thanks
I am not going to use my selector valve set up.When I had the hopped up 7.3 PSD in my truck I did away with it and tied the front tank to the rear tank w/a -12 hose.I did away with the factory pick-ups on the sending units also.I picked up from the front tank w/ -10(5/8) tube and hose and returned to the rear with a -8(1/2) hose.So the rear tank just fills the front as it goes down.It works real good.

Thanks for the info guys. I think I’ m going to take the selector valve off an older truck and replace my tanks with a set I have from a diesel. I found some wiring threads on ford trucks and it looks like the wires are the same weather it has a selector valve or a selector switch. Or there close enough that I can make it work. I might be starting this swap sooner than expected went to start my truck tonight and no start. If its anything major I'm just going to start the swap. I was hoping to start it next month. This truck is my plow truck so I hope it doesn’t snow. I haven’t even ordered my adapter plate yet.
I'm getting my plate from ford cummins. I like that I can use the dodge starter. Its cheaper to replace. I'm going to get engine mounts from them too. I called them today and left a message waiting to here back. Destroked doesn’t have mounts listed on there site for the obs ford. I went out this morning and my truck fired right up. I don’t know why it would not start last night. It worries me more now not knowing if it will do it again. I still have to pull the cummins out of my parts truck and fix the leaky gaskets, kdp, and paint it. Probably next week.
