Electric Fuel Pump....again

[Darren Groves]

I know this topic comes up on a regular basis, but couldn't quite find the answer I was looking for.

 

I know 2.5 - 3psi is the ideal operating pressure for carbs, so do the Facet 1.5 - 4psi pumps overpower twin SU's and therefore need a regulator or are they OK without?

A lot of classic car owners I know, who have either SU's, Strom's and especially Weber carbs are now using the Sytec regulator; such as Ebay 360872896996

 

I do not think you can depend on the pump delivering the correct amount of fuel at a certain pressure without incurring the risk of over-fuelling, but with the regulator you can make the pump do as you wish and not the other way around !!

 

Without a doubt using a regulator will give you the delivery you want for your particular car rather than just a broad sweep. 

 

If I had an electric pump on either the Vitesse (Strom's) or the Alpine (Weber) I would most certainly be investing in a Sytec. 

 

It is worth mentioning that if you do go for the electric pump option, ensure you install a cut-off switch to cut the pump dead should any problems occur; either as a fault or vehicle damage.

 

Best wishes.
