Though your FP differs from that with the L98, you cannot go wrong with the AC Delco unit for your car.

Kragen now stocks AC-Delco fuel pumps. At least the ones here in Sacto did for my 88. Cost $69. Much better than paying the dealer over $100 for the same thing.

Stick with AC Delco.
Just replaced mine this past summer, at 151K.
I'm the original owner of my '86 Vette. Lots of mods, too.

Replace it with a Delco from an '85 and add a pulsator. Convert your fuel regulator to adjustable and set fuel pressure to 13 psi. If you don't want to go with the '85 pump I have a new Delco for an '84. New style vanes with electrical connector, just may have a "this week only special". Regardless what pump you use the electrical connector will have to be changed, GM changed all pumps built after '87. It's not a big deal. There are step by step instructions on CrossFire Injection Vault. Site is down now but should be back up early in the week. :yesnod:

Walbro does not make the fuel pump for the C4 Corvette only the C5.
If you want a stock PnP replacement then a Walbro 190L/Hr pump will do just fine.
If you want something that will supply higher HP then a Racetronix + Walbro system woud be in order: http://www.racetronix.com/Racetronix-C43-FPK.html
