After swapping a donor engine from a 96 f150 into my 92 bronco, everything is now running great! The last issue I have is that there is a very loud whine coming from the gas tank that didn't exist before the swap. Any idea's as to the cause or resolution? It was a simple swap, 302 for another 302. Thanks

The fuel pump. They can make noise for years before failing. It may have been doing it before and you never noticed it because now you're actively listening for things.

Change the fuel filter and forget about it.

^^^^^^^ x2 Even a new pump can be loud to the point of being annoying. You may just not have noticed it before. The level of fuel in the tank will also affect how noticeable it is
