SU Fuel Pump replacement

[TRO]

What is the recommended electronic fuel pump to replace the SU original? Can an electronic replacement attach easily to existing bracket and fuel lines? any help gratefully received

You can get both a points and an electronic version of the exact same pump from Burlem. They do one with the low pressure output needed for a Stag. (which some are not).

I bought a Burlen last year. After requesting one for the Stag I received-



"The fuel pump that would be suitable is an AZX1308EN, priced at £120.00+vat and shipping.

This is single ended electronic type pump. Negative earth. High pressure 12 Volt with minimum flow of 15 gallons per hour. boot mounted."


I use a Filter/Pressure regulator set to 3 psi at the carb.

I fitted the electronic pump sold by LD part, ref ID: 591, which appears to be well regarded. GBP 84.74 inc VAT on 30/01/2023. LD Part fitting instructions attached for info. When researching this I found a review from November 2013 which, I believe, gives some of the early history - quite interesting.

+1 - No problems after 4 years. I did fit a Malpassi fuel filter/pressure regulator to check the pressure which was OK.

Mine has been in place for almost 12 years (40,000 miles) so far. I had confirmation last year from the New Zealand manufacturer that they were compatible with E10 fuel.

Pump creates a vacuum to lift the fuel from the tank. The motor O ring seal on that pipe is critical to the correct functioning take care when fitting. The pressure-side o ring never seems to be a problem.

Do not work on the pump without using an old rag to block the void into the wing below the pump which magically swallows bolts, washers and o rings with consumate ease never to be seen again.

Too right! Somehow on that occasion you develop Butter fingers. Then, you will also find that the job is held back because of a sudden shortage of replacement bolts, washers and 'O' rings which you have carefully hoarded for such occasions....

If the tank isn’t more than 1/4 full, it’s easy & quick to remove!
