So I have had a solid state facet pump for such a long time, its never played up however I decided to go back to a normal mechanical pump. - this one FUEL PUMP MECHANICAL pre 1990 CARS AND ALL 998 NON GENUINE - Mini Spares

Now i haven't as yet removed the facet so its unplugged but with the engine running the new pump seems to have so much pressure its gushing out of the overflow.    I rebuilt the carb with a rebuild kit and its still doing it!  Has anyone else had this problem with this pump?

Float stuck??  Or maybe install an inline pressure regulator?

I have had trouble with mechanical pumps from this supplier in the past, my advice return unit and stay with the Facet.

They should have 2.5 to 3.5 PSI.

 

I have had some new ones that after doing a good few miles (10,000-ish) have for some reason increased in pressure to around 7 PSI. I didn't bother going any further to see why. It's not isolated to a single pump either, but a few of them.

There is def something not right with it, I thought it may of been the float or stuck needle but thats why i rebuilt it.. anyway have removed it and sticking to the facet dad bought me in the late 90s :)    Maybe i will buy a new facet! 

 

Funnily enough saw a video on youtube tonight about the very same pump that dumped a tanks worth of fuel into the sump.  So its for the best but prob not worth the postage cost of sending it back.

Not really helping answer the question, as I too am in the change back to electrical pump brigade,   BUT has anyone ever measured the specs of the fuel pump  lobe on any cam????  It has never occurred to me, nor have i checked what the spec is on the fuel pump arm.... but are the gaskets also spacers????

Hardi electric pump all day.

Electronic fuel pump with pressure regulator is the solution - too many reasons not to use the mechanical fuel pump

Pressure regulators are a bad idea. They restrict the flow in order to reduce pressure. Buying the correct electric pump is the best idea.

Looking to install electric pump as my mechanical one has failed.  What pressure pump should I get and are there any silent pumps suitable.

So how would i fit an electric fuel pump for my twin hs2s without a regulator?

I think the low pressure facet would be ideal for you, it will pump 12 gallons an hour!

The factory fitted electric fuel pumps for many years to Mk1 minis and never used a regulator. They just picked the right pressure pump

By buying the correct pump. An SU pump or something designed specifically to replace them such as the ECCO 1LM12

I never hear my ECCO 1LM12
