Petrol Pumps

[Carl]

Do any Foramites have any experience with the Electronic Lookalike SU petrol pump? My old type SU's all need attention and I was wondering if I should replace them or try to find someone to rebuild them. Any information would be greatly appreciated.

the Electronic Lookalike SU petrol pumps do a good job

or you can fit a mechanical pump onto the engine

How you going Carl? Birthday bash today. You still selling your convertable.

The electronic pumps did have a bad reputation, early on, a niehbour had one on his MG & it played up more than the old points type, (but kicking the firewall didnt help )
This was 4 or 5 years ago & maybe they have sorted them by now, make sure there is warranty & carry your old one in the back.

We used an electric pump off a mazda (from memory) on my mates wolsley, it cost about 20 bucks from a wrecker, it is very quiet, not like some of the after market ones.
we mounted it down the back, hanging from a piece of heavy rubber, Then made a cover & painted it black, you would never know it was there, it pushes through the original pump up front, so it looks original, we just took the wire off the original pump, but the wire could be put back on in an emergency.
Of course dont use a fuel injected pump as they have to much preasure.

I still reckon the best way to go on an A series is a machanical pump, they go for years with out looking at them, & again you can run it through your original if you want it to look at first glance original (i should be the last one to talk about keeping them stock )

Hi DH & Trev,

Thanks for the information.
Things are fine up here, the weather is starting to warm up and that is what I think is giving my pumps a hard time.

I hope the Bash went well, they were good days. I half thought last week that I would drive down for it but I soon came back to reality.

The convertible was not ever officially for sale but the party showed some interest and we talked. It could still be available if anyone is interested.

As for fitting a mechanical pump, I can't fit one to the convertible being a sidevalve, and the Woody has an 1100cc engine and the place where the mechanical pump fits is covered by the block casting. I would have to bash it out and perhaps tap the mounting holes and I really don't want to so this.

I wonder if anyone out there on the forum is using one of these electonic pumps and if they could give me their impression of it.
Any help would be very much appreciated.

I ran a generic repco electric fuel pump on my morris 1100 for several years before I sold the car, never had any problems, it was a square block type

Hi Carl,
Are you referring to the electronic pumps that are the converted points type pumps or the squareish Facet type pumps that are sold over the counter in most parts shops?

I have used the electronically converted SU pump & found that it was even worse in hot weather than the original points type pump. It just would not pump fast enough to overcome vaporisation like the original could. This was very early on in the piece when they first appeared so they might have improved, speed wise but the electronics only help alleviate the points problems that appear, not vaporisation.

The Facet pump is great but it's a "pusher" pump & will not cope with being mounted in the original spot in the engine bay.
Having the pump mounted at the back helps to overcome vaporisation as it can force the fuel through still rather than trying to suck vapour up from the fuel line.

Hi Scott,

Thanks for the info. I guess I am referring to the electronically converted point type pumps. It seems that you are not that impressed with them. I was told by SU Midel that they were the "Bees Knees" last time I was in Sydney when I took an old one in to be rebuilt. They wouldn't rebuild my old one but would sell me an electronic one for a lot of money.

I do want to keep both my Woody and Convertible with the old SU type pumps where they are originally mounted. So I have 2 alternatives:-

I can mount a pump at the rear and pump through the old SU.
OR
I can get my old SUs rebuilt (preferred option).

Which brings up the next question.

Does anyone know where I can source the parts necessary for a rebuild and recommend someone to do the job for me please?

Su Pumps often come up on E Bay I have bought two and have run both of them in the car without problems. You can source new ones, both points and electronic from U.K. Try East Sussex Minors on the Web.

[Andrew]

I purchased my SU fuel pump through this uk company www.holden.co.uk as I found that some UK minor specialists required an exchange unit

Hi Carl our black one has a facet type near the tank and the original still in place. it is a bit noisy but no problems regards Heather

Sorry Carl, i've asked around, & as i said up top, & to cut a long story short, the new electronic, SU type pumps are crap.

Thanks everybody for your help and information.
I guess I will now move on to PLAN B when I work out what PLAN B is.

At least if you pay and get yours rebuilt by a reputable comany you will have some warranty.
Su Midel are are not cheap but they give great service and are quick.

[Carl]

Thanks for all the advice everyone.
I contacted SU Midel about a week ago and they no longer rebuild SU pumps. I think this has something to do with them not being able to provide a warranty because of old electrics. I also asked them if they had any spare parts they would sell me. They took my phone number and I have heard nothing since.
Would anyone be able to tell me what part of the fuel system vaporisation usually occurs and if there is any simple way to reduce it?

that
Solid State Electric Fuel Pump looks promising

nice it has differnt brass fittings

I would put it at the tank

[Triumph Man]

I have one of those square pumps in the boot, incase someones (not mine of corse ) pump dies, i just have some wire & a couple of alligator clips to hook onto the battery, & a cable tie to hang it somewhere, a couple of mate have used it to get home.
They work good but are very noisy, they never stop rattling away even when the fuel bowl is full.

Thanks Trev
I guess it should be mounted back by the petrol tank?
Any idea which volume/pressure would be suited for a Morris?

I saw two types and figures depending on the model morry

3 to 4 gallons an hour and the 6 to 8 gallons
