A more unreliable and recalcitrant device would be hard to find, never before in the field of automotives have so many, wasted so much time fiddling with them in fruitless frustration.

The only device that has irrevocably stopped me (and most of the people I know) on the roadside many times in 43 years of driving; even "new", electronic ones out of the box from our much vaunted SU carb people do not work or fail in a week.

They have no place on a CMP or any other vehicle for that matter and are debatably useful for hand grenade practice only. In the grand scale of usefulness the SU fuel pump runs a poor second to a fart in a colander.
