Electric Fuel Pump
I’m considering adding an electric fuel pump to my P1800S. It has a new mechanical fuel pump but it takes quite a few attempts to start from cold if left for a week or so (I know, use it more 💡. Would be nice to hear the ticking noise as the carbs are primed prior to turning over the engine
What bar pump should be used? Is there a preferred brand? I was looking to add it without removing the existing pump. My preference is to mount this under the bonnet rather than near the fuel tank. Thanks |

.you need.............
1) a Filter King or some form of pressure regulator--you need this so you dont flood the carbs. Some will tell you that the regulator is not necessary...up to you but given that if the pressure is too high and your carbs cannot take it .... think Crazy World of Arthur Brown ,,google him if you dont know the dance he did. Try to get a regulator that has the inbuilt filter that you can clean out or replace. Some of the cheap sh%t does not have them. 2) A Facet fast road pump..or and equivilant solid state one. If you have SUs or Webers they will run happily. Get a couple of rubber bobbins to mount it and that cuts any noise right down ..if you go for rally type red top interrupter pumps they are noisy and you will pay over the odds for a thing you dont need 3) wiring for said pump to your ignition or a secret switch if you want security 4) finally an inertia fuel cut off switch...second hand will do any car ----just in case like this https://www.ebay.co.uk/itm/FUEL-PUMP...oAAOSwbY5eB5fF but a Ford KA or any make really 5) finally finally a blanking plate where the old pump was on the side of the block..you can make one of those with a gasket All available off flea bay ,,,if you did not live in an uncivilised place like the South of England I would do the job for you for beer.....and a curry

pump
My car also sits unused. The turning over of the idle engine is not such a bad thing, it pumps the oil round before firing up. With a good battery its no great shake. I prefer to live with it.

The pump only wants to be about 3psi
I do prefer a mechanical pump but with how quickly modern petrol evaporates there is sense in going electric |

Thanks Grumpydad..but hardly a " boy racer" set up. SU fuel pumps were hardly the last word in reliability.They are also cumbersome. But I guess its an option although,
The set up I have described barring the " inertia cut off" switch has been used for about 40 years. Facet small cubed solid state pumps have been proven to be reliable. Sorry mate ,I cannot see the benefit of putting a SU fuel pump on at all , other than to take up space and costing twice the price.

I have another & much older classic car and this issue still comes up from time to time: ~ if the car is left then modern fuels seem to evaporate quickly from the pump. The general consensus is to keep the mechanical pump and I would agree-if it is in good condition then nothing wrong in terms of performance for these to include maintenance.
Some pumps had a hand primer on the older car I mention- very useful nowadays, a good point is also made by Volvo_133 regarding pre lubrication. Trust it helps Bob. |

Having looked at some YouTube videos, it seems possible to use the electric pump on a momentary button switch so that it’s only operational when needing to prime the engine. Once the ticking is stopped and it’s primed, the button is released and you can start the car only using the mechanical pump.
Anyone see a problem with this approach? Presumably, the fuel will just flow through the electric pump when not activated. Also seems a safer option. |

Using the electric pump just to prime sounds like a sensible solution
