A new Porsche 993 high-flow fuel pump will help provide the necessary fuel for proper combustion in your modified engine, but it can also serve as a good replacement for a stock Porsche 993 engine so long as your fuel pressure regulator is in proper working order and adequately managing the flow of fuel to your fuel rail and injectors. If you've made any major upgrades to your Porsche 993 engine or it's been a while since you've changed the fuel pump, it might be time to look into a replacement that will be able to better handle the job.

All of the power add-ons in the world won't amount to much if your Porsche 993 fuel pump isn't up to the task. Whether you need a stock replacement or a high-flowing unit, fuel pumps are responsible for getting the goods to your carburetor or fuel injectors. If your fuel pump isn't pulling enough gas or diesel through the lines, you might as well forget the rest of your mods until you can get the fuel supply side in order since your engine either won't run or will run so lean that you will risk overheating. Some of us have also ruined perfectly good fuel pumps by running our cars low on gas on the track, which overheats the pumps (especially in the turns), but the same can happen on the street. After installing a new Porsche 993 fuel pump, it is recommended to not let your tank get below half-full for at least the first few thousand miles.

Q: What does a fuel pump do? Why buy a fuel pump?
A: An electric fuel pump is a diaphragm unit that activates once your key turns in the ignition. It primes the pump and allows for a quick start.

Q: How do you install a fuel pump?
A: Most modern electric fuel pumps are found inside the gas tank. This should be left to the pros since there is a chance of accidental spark and explosion. Usually in the back trunk of the vehicle there is a fuel pump cover. This will need to be removed and the pump lifted out of the gas tank. Once done, the aftermarket pump will be swapped in its place and lowered back into the tank.
