The 1984-1996 C4s are far easier to change the fuel pump on than the 1953-1981 Corvettes
The cost of replacing a fuel pump on a 1990 C4 Corvette depends on the kit you choose. The ZR1 Corvette Replacement Fuel Pump Kit, for example, costs $219.95 for the standard volume and $247.95 for the high volume. The Walbro upgrade kit with adapters is also an option.
Changing the fuel pump on the 1984-1996 C4s is far easier than on the 1953-1981 Corvettes. The fuel pump on the 1953-1981 Corvettes was hard to reach and sometimes messy. The pump was low in the system, so you had to seal off the fuel lines and fuss with the fuel pump pushrod. If you were working on an air car, the HVAC compressor blocked access.
The 1984-1996 C4 Corvette’s electric pumps are easily accessible from the top of the gas tank. You can start the Fuel Sender Assembly replacement by removing the fuel filler door and the rubber filler housing. With the fuel door and housing removed, the top of the Fuel Sender is exposed.
The Fuel Sender is a combination of the electric fuel pump (or, in the case of 1990-1995 ZR-1s, a pair of pumps), fuel pickup, fuel filter, fuel level sensor and fuel level sensor float.

The fuel pump is easy to change compared to other cars as you don't need to remove the tank
The fuel pump on a 1990 C4 Corvette is easy to change compared to other cars as you don't need to remove the tank. This is in contrast to older Corvettes, where changing the fuel pump was a "pain in the neck" due to its low position in the system, which meant you had to seal off the fuel lines and fuss with the fuel pump pushrod.
There are a variety of replacement fuel pump kits available for the 1990 C4 Corvette, with prices ranging from $219.95 to $439.95. These kits include a new gasket, bolts, and a filter. The Walbro upgrade kit with adapters is recommended for beginners.
The Racetronix kit is also an option, although some users have expressed concerns about its performance. The wiring upgrade with this kit may take longer than the fuel pump replacement itself.
It is important to note that if you are experiencing fuel pump problems, it is recommended to have a phone and AAA card with you in case of emergencies.
