What are the numerous benifits? Sean

Re: fuel pump.... Jonathan wrote: I did have a 2cv, where the arm on the underside of the fuel pump had worn, so it started fine and ran nicely...till I came to an incline on a motorway and had my foot flat on the throttle, the engine died!! I would coast onto the hard-shoulder and the engine would re-fire and away again...till I came to another hill  The actuating arm that operates the fuel pump from the cam-shaft, had worn enough to allow the car to run perfectly well, till it needed enough fuel to climb a hill, but then allowed the carb to starve, so cutting out the engine. They do give problems with the actuating arm, see my previous post here:-

Re: fuel pump.... Are you sure? sticky valves in the pump would give the same symptom as the mech is under spring tension and the actual movement of the cam is only a tiny amount of what the pump is capable of any wear in the mecahnical parts is taken care of right i need to stop as im getting too anal about this i do have a life you know... and a real live GF honest!

Re: fuel pump.... I've worn one out! There's a rod attached to the diaphragm, which has a nipple (haha) at one end, which is pulled by a fork in the pivoted arm, which is then actuated by the pushrod from the cam. I've had one where that nipple had been worn away by the fork, meaning the diaphragm wasn't moving as far as it should. Coupled with a load of crud under the valves, I wasn't going anywhere... turning the diaphragm round 60 degrees and cleaning up the valves sorted it (temporarily  ) though!  It had taken 20 years to wear out like that.... I can see the virtue of a switchable pump, as others have alluded to, in a car that's left standing for ages at a time, to draw fuel up to the carb without wearing the starter motor out, but I don't think that describes your car, Joe!

It's on points, too.
