For the '95 940 with Bosch FI, the in-tank pump is the main pump and not comparable to the previous and cheaper in-tank pre-pumps. Bosch OE replacements can be had for under $100 USD if you shop around, so not overly pricey compared to fuel pumps in general and nowhere near what Volvo would have charged for one with their name on it. You'd pay more to replace an in-line and in-tank pump in the previous Bosch systems. You can get other brands of pumps for as little as $25 that will likely work just fine, just no assurance they'll last as long as the Bosch. Over half the value of the job to change the pump is getting the fuel pickup assembly out and back in to the tank. Without a few tips and a bit of practice you can waste a lot of time doing this job, with sedans being significantly more awkward than wagons to do. See the FAQ and search old posts here for more details.
