 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. 

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.

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.

Facet cube pumps are also popular motorcycle fast road and race. 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.
