Facet Metal Cube Pumps - Our Top Sellers (574a fuel pump)
 Facet 40104 pump

The 40104, 40105, 40106 and 40107 cube pumps are a popular upgrade for failing mechanical pumps on classic cars. They are used for both road and Motorsport applications.

Customers often ask us what the difference is between these pumps. From the table below it can easily be seen that the differences are in the flow rates and the pressures.

These 12 volt negative earth pumps have a dry prime height of 12 vertical inches and is best mounted both close to and level with the tank. Gravity feeding is even better. 

The pressure (psi) on Facet pumps goes up concurrently with the flow rates. Many carbs operate around 2.5 – 3 psi so when greater fuel flow is required and a higher psi pump is selected a pressure regulator such as Malpassi is often installed at the same time.

These pumps do not have check valves to prevent fuel returning back through the system when the vehicle is not operational. This is rarely an issue for classic cars and motorsport applications. The pump is self-priming meaning that fuel is supplied as soon as the ignition is turned on. For diesel lift pumps or for when it is desirable to prevent poor cold starting by ensuring the fuel levels are not drained from the float chamber & lines then 40254, 40288 and 40289 pumps have built in check valves to guard against flow back. These pumps also have higher dry prime height than other cube pumps

All Facet pumps are continuous operation and will carrying on ticking away even when they have reached full pressure. Unlike older style Interruptor pumps, modern Facets do no slow down or stop when they reach pressure

It is recommended to pre-filter Facet cube pumps. Facet fuel filter FPA906 is designed to screw directly into the pump and accommodate 8mm ID fuel hose. Alternately, an in-line filter such as Sytec’s Pro Flow glass filter is available with 6mm, 8mm or 10mm tails.

Facet cube pumps are also popular in carb motorcycle fast road and race applications. African Twins and KTM 950s are often sporting electric pump upgrades; 40171, 40104 and 40105 [low pressure].

Facet Posi-Flo Pumps
Facet's new Posi Flo pump

The black hosed Posi-Flo pump is the updated version of the Facet cube. Internally the pump is the same, the external black plastic housing offers more compact design that dampens the noise of these pumps. Although at 65 decibels it still lets you know that it is working.

The 60104, 60106 and 60107 are our best selling Posi-Flow units. Just like their cube brothers they are 12v negative earth and without built in check valve.

Frequently Asked Questions

Should the pump ever turn off?
The pump will always stay running as long as power is supplied.

Can fuel be pulled through the pump when the pump is off?
Yes, providing that you choose a part number that does not have an internal positive shut off valve.

Where is the part number located?
You can find the Facet® part number located on Solid State and GOLD-FLO® fuel pumps stamped on the mounting bracket, with two or three numbers on each side of the bolt hole. This number usually starts with a 40...

The POSI-FLO® and DURA-LIFT® fuel Pumps have the full part number dot-peened on the black housing.

How may amps does the Facet® fuel pump require to operate properly?
All Facet® low pressure fuel pumps 12v or 24v require an 5 Amps source to perform correctly. The DC average is 1.4 amps.

What size fuse should I use to install the Facet® fuel pump?
We recommend you install a 3AMP fuse to every installation.
Yes, All our low pressure fuel pumps can pump Gas or Diesel fuels.

Can I mount the pump in my car's engine compartment?
We recommend that you mount the fuel pump no more that 12 inches from the fuel supply (gas tank). All our Electronic fuel pumps will push fuel rather than pull fuel. Some pumps only have suction limit of 12 inches, therefore you should mount as close as possible to the tank. Each pump has a "dry lift" rating which must not be exceeded or the pump will starve.

Operating Temperature Range for Low Pressure Pumps?
Our pump are designed to operated in ambient temperatures of -40F to 180F.

How much fuel should be in the Dura-lift filter bowl during normal operation?
Due to the differential pressure between the interior area of the filter and the exterior area (between filter OD and bowl) and the sealing qualities of the upper filter gasket, you may observe a difference in the height of the fluid in the bowl of our pump. In addition, any other variable that affects the differential pressure will also affect fluid height, i.e. partially clogged filter. The more the differential pressure the lower the level in the bowl.

In any case, the fluid height cannot be higher than the pick-up, and the pick-up of the pump is 1/2 lower than the top of the filter and bowl. In a worse case scenario, the fluid is always traveling through the filter for proper filtration.

I just opened my new Facet pump and an oily fuel like substance came out. Did you sell me a used pump?

Your pump is 100% brand new. The substance is not petrol or diesel it is a special light solvent which will not harm your vehicle. Facet tests every pump prior to shipping, and some of the substance remains inside the pump. 

NOT INTENDED FOR AIRCRAFT USE
WARNING: FACET AND PUROLATOR FUEL PUMPS SHOULD NOT BE USED IN AIRCRAFT AS THEY ARE NOT DESIGNED, TESTED OR MANUFACTURED FOR ANY AIRCRAFT APPLICATIONS.

Positive Earth Pumps - Facet no longer manufactures positive earth pumps. All Facet pumps are now either 12v or 24v negative earth. With the help of an auto electrician, it is reasonably straightforward to install a negative earth pump on a positive earth vehicle. 

DISCLAIMER ALERT: The following information is for guidance only. It is not intended as an installation instruction. CONSULT AN AUTO-ELECTRICIAN BEFORE INSTALLING A NEGATIVE GROUND PUMP ON A POSITIVE GROUND VEHICLE. We are not auto-electricians and we do not offer installation advice for positive ground applications
Facet Cube & Posi-Flo Pumps - Two Wired Pumps
Electrical fuel pumps with two wires are reasonably straightforward to fit to positive earth vehicles [CONSULT AUTO-ELECTRICIAN to learn how to reverse the wires and earth the body of the pump]Facet Cylindrical Pumps - Single Wired Pumps
Single wire pumps must be isolated. This can be achieved by using the FACET FUEL PUMP MOUNTING RUBBERS FPA905 to insulate the body of the pump from the chassis [CONSULT AN AUTO-ELECTRICIAN to learn how to connect the positive wire from the pump to the chassis and the car's power lead to the pump]
