According to Volvo, the original pump has been replaced by a newer pump and hose. Here is a link to the Parts Bulletin.
It looks like the latest pump is still available in Europe. I would suspect the same would be true in the USA. Here is a link to the pump from MarinePartsEurope.

I would try Volvo Penta USA or your local Volvo Penta dealer and see if they can get the parts.
If you decide to convert to an electric fuel pump, you might look at the Facet Duralift series of pumps. They are commercial duty pumps and very reliable. Your original feed pump is rated at 9.25-12.1 p.s.i. at 2520 rpm, so be sure to select one of the proper pressure. You should also fabricate a block-off plate and remove the old pump.
Here is a link to the Volvo Penta service manual for specs.
