INFO
The pump is compatible with Gas, Methanol, and Ethanol.
The MF Fuel Pump is constructed of out of billet aluminum. Internal hardened gears are hand lapped increase lifespan and reduce the coefficient of friction. The gear housing is constructed from Anti-Galling and corrosion resistant material and further DLC coated to resist the low lubricant properties of alcohol based fuels.
Its small size and weight can supply huge amounts of fuel. The Magnus MF Mechanical fuel pump supports up to:
9.7 GPM @ 40 psi relative pressure @ 80% IDC at 5000 RPM of pump speed (1/2 engine speed) 2800HP on Methanol 4300HP on Ethanol 5700HP on Gas
8.5 GPM @ 60 psi relative pressure @ 80% IDC at 5000 RPM of pump speed (1/2 engine speed) 2500HP on Methanol 3700HP on Ethanol 5000HP on Gas
Construction we use a Gerotor positive displacement pump, which provides lighter weight and impressive low speed vacuum for priming of engines. Because of the Gerotor’s construction it is imperative that a clean fuel supply is used. because of the almost 10 GPM flow of our pumps we have developed special fuel filters to handle the high flow and high filtration.

- Magnus Pumps use very tight tolerances, to ensure safe operation you MUST use pre and post fuel filters.

FAQ
Direction of Rotation :
Clockwise rotation, when looking at the front of the pump (shaft side facing you) : Right side is inlet, left side is outlet
Counterclockwise rotation, when looking at the front of the pump (shaft side facing you) : Left side is inlet, right side is outlet
- Many people use them on street cars, they will usually retain the prime for 1 week. As long as you run a pre filter (40 micron) to protect the pump and a post filter (10 micron) to protect your injectors
It will do over 250 psi of pressure we just don’t recommend 100 Psi of base pressure because of the myriad of problems associated with running such a high base pressure. Number 1 is increased load and wear on the pump and associated components. Most regulators cannot reliably handle over 120 psi of pressure, they tear the diaphragm. Most injectors are designed to run at 45 to 60psi of pressure at anything 0ver 105 psi most injectors do not open reliably on the test bench at 12v. There are other issues as well as overheating of the fuel, and the fact that most 2200’s actually lose flow volume at elevated temperatures. These are just a few of the reasons we recommend people to run between 3 bar and 4 bar of base fuel pressure. In your case I would recommend Larger ID2600 injectors or another 4 injectors which is becoming the norm with all the Mitsubishi and 2JZ crowds, 3 injectors per cylinder.
- Do not run dry for any amount of time.
- Make sure there is fuel in it when running
- Make sure the only thing in-front of your fuel pump is a pre filter, no check vales etc.
- Do not “Y” other things into your fuel system and check valve will only cause problems
- Make sure there is a VENT in your fuel tank or you will not be able to draw fuel out.
- When assembling new fuel lines run air then water through them to clean them out of any debris. All of our pumps are tested on our fuel pump bench for 20 minutes. They are particle free if you develop any scoring you have contamination
- Marketing video showing how to prime a fuel pump
- We recommend running between 3 – 4 bar of base pressure (43.5 – 60 psi)
1) Which regulator do you recommend with this pump?
- We recommend running between 45 – 60 psi of base pressure
2) Is the drive belt a concern of failure or high maintenance?
- Belts rarely fail
3) Is a pump required to feed this or can it draw fuel itself? Otherwise just prolonged engine cranking?
- It can draw fuel itself but it up to you to provide a good source of fuel, of course running dry is not recommended.
4) Do you recommend using a check valve?
- You should not under any circumstances use a check valve as most check valves cannot flow 10 gallons per minute this will starve the pump and your engine at high rpm
5) You must use a low micron pre and post filter that flows over 12 gallons per minute
- Most commonly available regulators will bypass enough for our pump we have tested it.
