Is it normal for the electric pump on a Plus 8 (1970s) to tick all the time? I can understand why you might hear it ticking/pumping when you initially turn the ignition on and the carburettor/fuel lines etc are filling up, but I would have expected that to stop after a few seconds (without actually starting the engine). Or does the pump tick (ie run) all the time even when there is no actual fuel flow into the carb? (There is no return fuel line from the carb).

Many thanks

Yep. That's a Facet copy.advertised as being suitable for an SU/Weber/Dellorto/Solex/Stromberg Pierburg/Nikki Carb. Not an SU Fuel Pump. As Arwyn said, best to avoid the cheap copies and pay a little more for a genuine one.

Anyhow, to get back to the OP, you have a genuine FACET pump (the square red sticker is the giveaway) and it should click all the time so there's nothing wrong with it and it doesn't need replacing.

You can add a Rubber Mount Kit which lessens the noise slightly but there may not be room.

Just to add to the confusion, the Facet pump was previously known as the Bendix pump.

Most of the Mk2 Escort rally prep manuals from the 1970's refer to it as such .

Used to run double pumps in the rally cars; wired up so you can change over on the fly.

Used to change them at the start of every season for reliability

Steer clear of the cheap copy pumps - absolute crap
