Frequently Asked Questions (FAQs)
1. How much horsepower can a mechanical fuel pump handle?
A mechanical fuel pump designed for performance can typically handle horsepower in the range of 750-900 hp. This level of horsepower support ensures that the fuel pump can adequately supply fuel to high-performance engines.
2. Does a performance fuel pump make a difference?
Yes, a performance fuel pump can make a difference in engine performance. While it doesn't directly increase power on its own, a high-flow fuel pump allows for a higher flow of fuel to the engine. This becomes particularly important when major engine upgrades are performed, as the increased fuel flow can support the increased power demands.
3. What are the disadvantages of a mechanical fuel pump?
Some common issues associated with mechanical fuel pumps include fuel leakage into the crankcase due to a ruptured or leaky diaphragm, vapor lock in the pump, fuel pressure drop, and faulty diaphragm spring. These issues can affect the performance and reliability of the fuel pump and may require maintenance or replacement.
4. Can a fuel pump be too powerful?
Yes, it is possible for a fuel pump to be too powerful for an engine's requirements. While an oversized fuel pump won't over-fuel the engine itself (due to the fuel pressure regulator), it can result in excessive fuel pumping within the system. This can lead to unnecessary strain on the fuel system and potentially cause issues.
5. Does E85 ruin fuel system?
E85, which contains a high percentage of ethanol, can be harmful to fuel lines, fuel pumps, and other fuel system components that are not resistant to ethanol. If you have a vehicle with an older fuel system that is not designed to handle ethanol, using E85 may cause damage. It is important to ensure that your fuel system is compatible with E85 before using it as a fuel source.
