Hello, has anyone fitted this petrol pump in his Mini? Do you think if is it enought to feed a "twin Hs2" carb?

Regards!

[nicklouse]

Do you have a link to the specs of the pump?

 

What is the engine? That and it’s power output is of more importance that the fact it has two carbs, it still need the same fuel if it was a suitable single carb.

I've used quite a few of them now.

They would easily be well up for 100 HP and probably more, so feeding twin HS2 wouldn't be an issue.

 

They are a great pump and I go for these over the SU Pump.

Are parts for them available?

just get the correct one.

Does it suck well enough to be mounted on the bulkhead, going up an incline ?  or is gravity fed, below the tank ?.

While they are not rated for this, in our Mokes, there's about 2 metres of fuel line and a lift of 600 mm and they draw up from a dry line on that quite OK.

I actually had a Morris Minor SU Pump (that I bought new) in there prior to using the Hardi Pump. It is (as you'd know) rated for lift and long fuel lines, but it was hopeless. Not just this Pump, but the same type of Pump (again new) in a mates Moke too. Since swapping over to these, we've not looked back.

Hi guys, thanks for your answers. Here is the problem; Morris Mini 1275cc with twin Hs2 carbs, and the car from the first day I fitted this new pump, it goes totally irregular.
The flow of fuel is too poor. Do you see anything strange in the photo?

Regards!

A couple of things spring to mind here.

 

1: Are you using brake line for your fuel pipe??

2: Where the rubber pipe is routed around the electrical wiring attached to whatever that solenoid / pump??? is looks crushed/compressed.

[nicklouse]

seems odd to have the pump on that side of the floor as the tank and piping is all on the other side.

 

what is all that other stuff?

[cal844]

Personally I'd mount it to the other side of the subframe, away from the exhaust.

I second the question from Nicklouse.

First thing I'd suggest checking is you have a good electrical supply to the Pump. You really want to run a minimum 1.5 mm² wire to feed it and be sure you have a good earth.

 

This next check, you'll need to be a bit careful while doing this.

 

Disconnect the fuel hose at the outlet of the pump and check the flow rate there. As the Pump is lower than the tank, beware that as soon as you disconnect the fuel line, fuel will gravity flow out of it. even before you switch it on.

 

With the power on to the pump, it should free flow at least 1 litre a minute.

 

Next, check the pressure. It should be around 3 PSI.

 

Connect the Fuel line and do these same check up where it connects to the Carbs.

 

As Sonikk4 touched on, your fuel hose routing and solid lines look a bit small. They need to be a minimum of 1/4" (6.3 mm) and preferably 5/16" (8 mm). The barbs on the Pump are 5/16".

 

If you don't mind me saying so, the installation here is not 'tidy'. Ideally, it should avoid the exhaust pipe as heat to any fuel line can cause issues (though I doubt that here) and the pipework should be installed as neat and straight as possible.

Fantastic and super complete answer. Thank you very very much Moke spider.

and thanks also to the rest of the classmates. To say that I could not to fit the pump on the other side because I have this:

The a.a.

The electrical assembly is done by a professional. The ground wire is good.

But I have a question, could it be that the pump is giving little flow because it has to be placed vertically and not horizontally?
