I have Ecco pumps on 2 minis at present and will be fitting another when the mechanical pump packs up on my wife's mini. They are the correct pressure for a mini, if you buy the right model. It acts exactly like an SU Pump, only ticking when the fuel pressure drops. I believe they are pos or neg earth and come complete with mounting bracket etc.
A New Zealand product which I know is used on Morris Minors. MGB's etc. think they're on the Fuelsave website, where you can see the various models available.
I recommend them. (hopefully I'll get a parcel in the post after this)!

 
Have you tested the pressure?

No. these are the ones I use. 2 - 3 psi. https://simonbbc.com...Ss10amEhL5xj6fC
One  is on a 1293 with 80bhp and the other is on my 1098 with 78 bhp. Absolutely no problem with float valves or modern fuels.

That ECCO fuel pump model is exactly the one I was looking at yesterday. It delivers between 2 and 3 psi, which is precisely what a twin SU HS2 carburetor setup requires. Therefore, installing a pressure regulator might not be necessary, as it won't flood the carburetor float chambers.

Whistler, would you be so kind as to tell me what place have the ECCO pumps installed in your cars?

Many thanks in advance!
Kind regards

Cheers man !

That is the ecco that I have.
 
I find it peaks at 4.5psi and the pressure then drops due to the needle leaking.
 
Even the manufacturer now says 4psi: https://fuelflow2020.nz/?page_id=188

4.5psi?? The specifications say;"Operating Pressure(Psi) 2 – 3 psi". Are you using a regulator of pressure friend? And your carburettor is?

I have a facet on 2 cars and a cheap ebay special (hep 02a) on another, the cheap pump performs just as well as the facets, will draw from the engine bay and is quieter.

No regulator, HS4. I'm sure I could get better economy with lower pressure.

 

If you look the the manufacturer's current website, this is what you'll see:

Scroll down to the spec list and it states 2-3psi. Can't see that 1 psi makes any real difference especially as the pump is not operating all the time like a facet.

I believe what happened is the manufacturer used to specify 2-3psi and that is the description most sellers are still using. The Website I linked to is the current manufacturer's website so should be the most accurate (they have gone through a few different websites in recent years).

 

When talking about 3psi, 1.5psi is a BIG difference. Especially when 3psi is already on the high side of what is ideal. That is why so many people have been fitting fuel pressure regulators.

A new discovery of mine is that the ecco will slide out of it's bracket if you drive on rough roads.
