Fuel pump (rebuild Bosch 044) (340) for E85/petrol

A rebuilt Bosch 044 pump adapted to cope with ethanol (E85) and optimized for better flow.
This fuel pump has, on average, about 5 times as long life on E85 as a standard Bosch 044 pump.

One of the very few inline fuel pumps on the market that is made for ethanol.

Of course, this fuel pump works just as well on petrol.

Flow at 13.5V:
340L/H at 3bar
310L/H at 4 bar
275L/H at 5bar
210L/H at 6.5bar

Maximum working pressure: 9 bar.

Input connection: M18 x 1.5
Output connection: M12 x 1.5

3 bar - 11.6 A
4 bar - 12.8 A
5 bar - 13.5 A
6 bar - 14.7 A

Please note that test environment versus practical use can have widely varying conditions depending on peripheral equipment and other technical factors. However, this is very good information on what you can expect from the fuel pump and basic information when choosing other components in the fuel system such as fuel spreader, fuel pressure regulator and fuel filter.

A new fuel pump has a break-in period where it "breaks in" to finally flow properly.

This EFI / high pressure fuel pump can also be used for carburetors if the correct fuel pressure regulator is used.

This fuel pump is tested on E85 from the pump. Not tested or approved for race ethanol fuels.
If you use the fuel pump on race ethanol, you do so at your own risk and it is not something we recommend or that covers any guarantees.
