1995 Cadillac Seville Fuel pump fuse keeps blowing

there is a larger than normal draw on that circuit.based on the information you have provided I would suggest that you either have a severly restricted fuel filter or an overheating fuel pump.you could try the filter first and see if it helps,but don't be surprised if the pump is already damaged.

This is a different expert.
The fuel filter isn't going to blow a fuse and neither is the pump unless it is shorted out internally. My suggestion is to replace the oil pressure sender. It provides a redundant power feed for the fuel pump, powered by the same fuse and can short at specific oil pressures.

b.s. wrenchtech,so your saying that a severly restricted fuel filter could not put to much strain on the pump and make it pull to many amps and blow a fuse?

Yes, I am................. A severely restricted filter could elevate current draw slightly but never to the point of blowing a fuse. I see pumps seized solid with the relays jumped out and still don't come close to blowing a fuse, especially at idle like this one when voltage is at it's lowest..

I tried looking up the oil pressure sender but could only find a oil pressure switch. Is that the right part?

Yes, just another name for it.
