Each fuel pump assembly has a valve that prevents fuel from being pumped to the wrong tank. The tank that receives fuel when it shouldn't has the bad valve and the fuel pump assembly needs to be changed to fix it.

For trucks w/o a separate hi pressure pump on the frame rail.

Would you happen to know what the cost of fixing it may be?

The cost of a new pump assembly and whatever you pay whoever puts it on.

I don't know you personally so I don't know if it's a bad idea. I'd say it's a good idea if you're mechanically inclined.
