How does the AUF214MS electric pump compare to the mechanical pump’s output pressure?

 

I was running mechanical pumps for many years a while back, but, as Nick mentioned, the heat from the exhaust was a worry. I found in recent years 2 issues with the current mechanical pumps, first one was when warm (not even hot) they had a lot of trouble sucking fuel up from a dry line - often taking every last electron in the battery to do so, not just my experience here, but a few who I travel with.

 

The other issue was that over time, the output pressure would increase to the point that they overcome what the Carb's Needle & Seat could cope with.

 

A few of us initially swapped out to the genuine SU Pump, but have been disappointed with their poor output pressure, it was fine to start with but over about a year, it dropped to around 1 PSI and all we needed was a slightly blocked or wet filter and we'd starve for fuel. I can't see why these are doing this and there's no way I can see to adjust them.

 

Back in 2014, I swapped over to these German made Hardi Pumps from Mini Spares and haven't looked back. They are very well made and hasn't missed a beat. I haven't checked the output pressure of it recently, but when I first fitted it it was bang on 2.5 PSI. Pleased as punch with them.

Thanks for the reply. I ordered the pump and the rest of the installation hardware today.

Rover inertia kill switch. Hmm. Would you have a part number?

A friend has one fitted, and pot holes will trip it off.

 

 

The Vulcan Bombers had a contact breaker that cut out in the event of an electrical surge.

 

To re set the kill switch, someone had to stand on a step ladder and open a little hatch under the fuselage.

 

It crashed in South wales, killing all on board.

 

If you are going to have an inertia kill switch, mount the darned thing where you can reach it with out having to get out in the fast lane of the motorway.

I have mine mounted under my seat, close to the hand brake lever, mounted vertically on the cross member
if anything happens its a touch under the chair to pop it back in and keep going ;)

Facet solid state pump mounted to rear subframe on my estate, reckoned I might need a good flow to feed the 1275 supercharged motor.

This pump is mounted on the bobbins, wired through a relay of course.

Seems to work fine so far, thank goodness the engine is loud otherwise this would be pretty annoying with it running all the time.

 

I also have an inertia cut off switch mounted on the front edge of the crossmember, just in front of the passenger seat, I don't have a photo of that though.

So if I do hit a bump I can reach over and check the inertia hasn't tripped.

safety first eh.

Mount a Morris Minor pump near the wiper motor.

 

Wire it through the dashboard light switch....................so that you can isolate it.....................but tie a knot in something, or next time you start, you'll be lucky to get more than 100 yards.

Sorry, am I missing something?

SU made an electric fuel pump that was fitted to the bulkhead of a Morris Minor, not like a Mini, in all the mud and wet under the back axle.

 

 

If you take the electric supply for the re-positioned pump, from the back of the instrument panel switch, by switching off the panel lights  you will cut the power to the pump.

 

If someone were to steal your car, with the pump switched off, the fuel in the carb is enough to drive about 100 yards.

 

If a car stops in the middle of the road, people will notice, which is not what a thief desires.

 

The same would happen to you if you forgot to switch on the panel lights before starting the engine.

 

Hence the advice to "tie a knot in your handkerchief" to remind you to switch on the panel lights.

I've had a few of old British cars in the past that have had a standard electric SU pump at the back under the floor somewhere. There's four good things about having an electric pump. One is that you keep fuel lines further away from the exhaust with minis, another is that you can pump out the tank/tanks into a container without running the engine. Another is that you can fit a pump kill switch as a saftey feature.

 

One last thing is that you can fit that kill switch somewhere easy for you to find in a hurry if you need it but have it out of sight. I fitted the switch under the parcel shelf on my MkII Cooper S. The idea being that I could switch the pump to the off position if I was parking it somewhere when leaving it for a few hours. Say in a multistory car park one evening. If anyone tried to nick the car and got it started (easily done in an old mini), they would only get out of the car park and out onto a road, where people were milling about and the engine would stop. The theives would give up trying to start it and run off. Well, that was the theory thirty years ago. I don't think I'd leave it unattended in a multistory car park these days though. Back then it was my everyday car.

 

I did do the same mod to an MG Midget that I used to have and it did get nicked one evening. It was abandoned about 50 yards from where it had been parked. There's probably much better immobilisers out there these days of course, but it was simple then.
