Can you push fuel through a mechanical fuel pump?

Can you push fuel through a mechanical fuel pump?

You can push fuel through a lot of mechanical pumps but I don’t know about yours specifically. You electric will work better if you mount it near the tank but you can probably get away with mounting it in the engine compartment. I’ve run them that way in a pinch no problems.

Does a mechanical fuel pump need power?

It consists of a mechanical pump (basically an internal impeller) that pumps fuel through the unit and to the engine. It does not take any electrical power to operate as it drives off the crankshaft via a hex adapter or cog belt attached to the crank pulley.

Which is more reliable electric or mechanical fuel pump?

Usually, a mechanical pump is preferred over an “aftermarket” electric fuel pump. They tend to be more reliable.

How do you size a mechanical fuel pump?

A good estimator of volume to power is approximately 10 hp per gallon or 2.64 hp per liter. For example if your pump flows at 50 gph it should be able to support a 500 hp engine (50 x 10 = 500). However, to actually know the gph you must also consider the fuel pressure required for your engine.

What kind of fuel pump do I need for LS engine?

External Fuel Pump. These pumps deliver 6 to 14 psi, not nearly close enough to the 60 psi required to operate an LS engine. Any less than 60 psi and it leans out and does not run well, if at all. Thankfully, there are plenty of in-line EFI pumps to choose from. Many builders prefer the Walbro GSL 392 external pump.

What kind of fuel pump does Aeromotive use?

This pump features a 255L flow rate and is very popular for LS engine installs and EFI conversions. Aeromotive 11569 – In Tank fuel pump – A great option for keeping a factory looking install using the OEM sending unit while supporting an increased flow rate to 340L.

What is the best fuel pressure for an LS engine?

Most LS engines operate at 58 PSI, as well the most popular EFI systems operate anywhere between 48 PSI and 58 PSI. The exception to this would be Gen V LS engines with direct injection which have a higher-pressure requirement. Always choose the proper fuel pressure regulator for your application.

What kind of fuel pump does Aeromotive 11569 use?

Aeromotive 11569 – In Tank fuel pump – A great option for keeping a factory looking install using the OEM sending unit while supporting an increased flow rate to 340L. This pump follows the GM style design but still supports many different applications. A popular option for higher horsepower LS swaps and EFI installs.
