While under the car check the metal pipe which runs from the petrol tank to the pump, if in doubt renew this as well. This is a ready manufactured item with swaged connections at each end. If you have a leak in this pipe it introduces air into the fuel system and changes the mixture.
When locating the new pump ensure that you connect the breather pipe and the electrical connections securely and tighten the bracket in place. Instructions on repair, reassembly and adjustments of the pumps can be found in the shop manual or the Haynes manual for all of the cars. The information on the fuel pumps for the TD is in Section B. For all the other models, you will have to search your manuals for the information since I don't have the manuals for them.
Below is a list of the people that I know of who work on SU fuel pumps. If you happen to know of other people who work on the SU fuel pumps, please let me know and I will add them to the list. Tom Ball - or Dave DuBois - ddubois sinclair.
Pacific time please Jerry Felper - felperg earthlink. SU Midel Pty Ltd. Note: If you also repair SU fuel pumps or know of somebody not listed above who does, please send me an e-mail with contact information for the person so I can add them to the list of people to contact for fuel pump repair.

Last edit at PM by joaniebo. Spent several hours yesterday going to various places looking for some small plastic polyethylene caps that I could use to plug the banjo fittings on the metal line and braided hose leading to and from the fuel pump.
On the 4th or 5th stop, a fellow suggested that I try a local large truck repair shop. I walked in, explained what I needed to the parts guy; he took my old fuel hose from the pump to the metal line leading to the carbs ; returned about 4 or 5 minutes later with several blue plastic caps that slid tightly into th banjo fitting.
So today, I again removed the banjo bolts from the pump, plugged them with the "little blue plastic caps" Clipped on the hot and ground wires, hooked up the battery and Would wholeheartedly suggest that if anyone is planning on replacing their SU pump, replace it with one of the new, electroinc no-points pump! San Francisco, USA. OK - update on MY experience - MGB with brand new SU electronic fuel pump - did test with checking the fuel pump connections with my little lamp tester - the light lights!
Shall I get a VOM to test how much juice is reaching those wires?? Really grateful for your help as it is frustrating. To reply or ask your own question: Members Sign In. Create an Account. Join The Club. Sign In Create Free Account. Dave L MGB. Website problem?
Morris Minor Forum. Vintage Race Forum. Another SU perhaps? I gave serious consideration to this as I had fitted one in my Lotus years ago though the reliability of the cube pump proved to be a bit questionable.
But there were also issues in going that route as well…. Mounting was one. Another was accurately regulating pressure easier said than done when you are talking about low pressure around PSI. Not only would the purchase of the pump be needed but also a pressure regulator. It sounds like someone bolted a buzzer to the frame rails. Part of that character or charm is the gentle clicking of the SU pump. And be more affordable. Not asking for much, eh? So I started doing some research.
I heard mention on British car enthusiast message boards of SU style electronic replacement pumps being available, but made of plastic. I was intrigued. There seemed to be opinions on them having questionable reliability and construction. I found a lot of opinions and anecdotal experiences, but not a whole lot of facts.
I contacted the vendor for more information since their catalog description was very brief. Unfortunately, little more was learned about this pump after my discussion with them and I decided to send the manufacturer an e-mail for more information.
Not a country that pops to mind for automotive products. Heck, the only things I could think of that came out of New Zealand were Hobbits, Xena Warrior Princess, and a wool sweater in my closet. After a bit of research I found that New Zealand has a lot going for it.
A government that promotes exports, a small but high quality manufacturing base, low taxes, great standard of living, a highly skilled and motivated workforce, and the lowest incidence of government corruption in the world! Oh, and the incredible scenic beauty of the place has to be mentioned. Use Google street scene and plop down just about anywhere in the country and have a look. Absolutely stunning!
I was pleasantly surprised my e-mail inquiry was answered within an hour. Not by a customer service guy or a sales rep, but by the president of the company, Mr. Graham Wilkinson! After all, who is going to give a straight answer to such a question? Knowing the character of a company is important since it will be reflected in whatever they make.
Ken Hogg who operated under the name of Service Units Limited. Hogg was an auto electrician who acted as an SU Service Agent or what would likely be known today as a Factory Rep until the mid s. After many years of seeing some of the design and technical shortcomings of the pumps he was working on, he felt he could do better using more modern materials, electronics, and assembly procedures. From the onset, he chose to use the then very modern material of plastic, which had comparable wear, durability, cost, as well as superior corrosion protection over metals.
Building on this success, the company introduced a line of piston type pumps in — again entirely in plastic — again with great success. There was a period of international growth with their pumps being picked up by MOPROD in Europe, a major parts reseller, as well as other similar sized distributors throughout the world. Here is where the story takes a few weird twists….
At this same time, they began supplying pumps and more crucially — plastic pump technology — to another pump maker and supplier in Germany, HUCO.
I understand that these pumps by HUCO are still available, but appear to not have been developed further beyond their original introduction spec. Enter the new century and Mr. Ken Hogg, despite international success with these pumps, contemplates retirement but with no succession plan for the business also assumed it would go into retirement as well. Graham Wilkinson who purchased the company in May Fuelflow Solutions Limited is still a privately owned company, not part of a vast manufacturing empire.
All they make are fuel pumps. And mostly by hand. By really skilled people whose fingerprints you will see on every pump if you look closely enough. A specific example of this advancement can be found in the material used in the construction of the diaphragms, which is unique to Fuelflow.
Since introducing the new material 10 years ago, not a single diaphragm failure has been reported, and when you consider that this is a traditionally weak point in this style of pump this is a very worthwhile enhancement.
They may be the only manufacturer using optic switching in fuel pumps. Wilkinson is proud of his company and workforce. They are NOT made in China!
