It is a Mossberg 500AB and they made it for Western Auto under their revelation name. So all 500 Mossberg parts are compatible with the gun. I hope this answer helps you with your question.

One can find a Bosch fuel pump on the Bosch Auto Parts website. If you don't trust that company then you could go to auto parts forums or look up reviews on Bosch Auto Parts.
I have a revelaion model 300f as well. I do know that it was sold at Western Auto stores, but not sure about the dates it was manufactured in. The gun was manufactured by Stevens and sold through Western Auto stores. I have found that is the same as Stevens model #77C, but unfortunately that is all the information I have about it as of now. Hope this helps you out some.
Revelation was a "store" brand for guns made by others, but sold by Western Auto hardware stores. We need to know the model number, but most are worth $150-$175, depending on condition.
