Electric fuel pump recommendation

Folks,

I need to replace the electric fuel pump on the DS. It's non-original: fitted by the last owner in South Africa to refill the carb after long periods of standing in the hot sun of KwaZulu Natal and now jolly useful when starting on a petrol after running on gas.

What's there is a.n.onymous plastic thing with spigot (ie not-banjo) inlet and outlet fittings. It would be easiest - though not essential

- to fit something similar. Since it is in series with the mechanical fuel pump (I am not going to change that) it needs to have a reasonably low resistance to having fuel pumped through it.

A quick look round suggests that the choice is SU, SU copy, Facet and Facet copy. Any advice or horror stories most welcome.

What? You're crazy! Fuel? Pumping it? On a DS?!! Why would anyone even contemplate doing that? Oh, sorry, wrong thread.

I've always got on very happily with SU pumps. Just two points to watch, I suggest: there are S.U. variants for high suck, low blow (e.g. Morris Minor, Derby Bentley) and low suck, hard blow (BMC 1100, Mk VI Bentley); and some of the alternative makes may have a rather high delivery pressure, in which case you may need a pressure regulator.

have a range of makes;

have some bumf about S.U. pumps, iirc.

The Rover P4 and P5 (but not the P5b) had a low suck, big blow pump too, only theirs was a complicated arrangement with two inlets taking main tank or reserve tank supplies.

Mostly, it matters where the pump is located relative to the tank, and whether you need to lift petrol from the tank or whether the tank is high enough to serve the pump by gravity.

As things stand the pump is on the bulkhead, about 2' above the tank, which is under the back seat. I shall investigate to find what pressure the mechanical pump produces. At the moment the electrical pump blows fuel through the mechanical one, but that could be reversed without too much difficulty.

It sounds like the Morris Minor one might be best. But try giving Burlen a ring. I have always found them knowledgeable and helpful.

If you are going to fit a new electric pump you might want to think about not having it sitting in all the heat under the bonnet, but putting it down by the fuel tank where it and the petrol in it and the pipes keep nice and cool, in case we ever get a summer again. This would mean using just about any pump other than the Type L SU fitted to the Morris Minor (among many others) which is a lifter, not a pusher.. If you are considering a mechanical Facet (rebadged Bendix), be aware that it keeps ticking even when it isn't actually moving any fuel. Being fairly modern you could probably use an electronic Facet - I don't know about those, but I would assume they are silent.

Some of the Facets - rectangular box, inlet and outlet aligned - looks as if they may be rotary pumps rather than reciprocating. Do you, or anyone, know if this is true?

No idea, but I have one on my 2.0L Capri, and it clicks...

Ah. But does it stop clicking when the float chamber is full like an SU does or does it carry on, albeit slightly muted, like the older Bendix style Facet?

No, once the float chamber is full, the "tone" changes, you can hear the change if you're paying attention...
