Your orig gauge is calibrated to your 50 lb sender.In 46 Ford went to the 80 lb.If you can take the guts of a 46-48 gauge grafted to your 40gauge I don't know. To change the pump you need to pull the pan.The wishbone and drag ling will be in the way.

Here is a 51A 80 lb gauge.Looks like you can switch out the face and it could work.You'll need the 80lb sender which there are a lot of.
