Series 3 109 2.25 petrol
Has anyone put an electric fuel pump on a series?
How easy is the job and where to get the pump?
All advise greatly appreciated

no...but did put one in 2.5 diesel defender.
No reason why you can't put one in, I don't think. They are available from most Motor Factors...or that well known online auction site

have a look at facet fuel pumps i think the one you would want is a 40147 but you would want a pressure regulator by the carb

If you use a leccy pump then remove the lift pump, I'm sure you've done that anyhow.
The pump will be more beneficial at the back near the tank.
Personally I'd go to a breakers and get a inertia switch off a rover metro (just under the screen passenger side) so if you have a bump the pump shuts off.

I did this in a my Series trialler.

You will need a fuel pressure regulator and wind it down to about 2psi, any higher and the fuel pressure will force the float valve open. Also consider putting in a T-piece at the carb and plumb in a return pipe, this will ensure a circulation of cool fuel which helps with hot running.

I wired mine via some relays so that the pump turned off when the oil light was on and visa versa, but would run when I energised the starter motor solenoid. An inertia switch from 'just any' car can be a double edged sword off road......particularly in a trials motor

Thanks for the advise.Not quite as straight forward as I anticipated. Can anyone recommend the parts required and source

Andys quite right, connecting the pump to the oil light via a relay is a better idea, I'd not thought about the off road bit affecting the inertia switch, you dont wanna bump into a big puddle and end up with no fuel.
A injection vehicle pump will need a pressure reg, but if you use a pump from an older car or one designed to be used with a carb, the output pressure is a lot lower and you wont need the reg.
