 Electric fuel pump Hi there I've bought an electric fuel pump as my mechanical was giving symptoms of being a bit weak at higher revs. Wondering what I need to do regarding the old pump! Curious as to what would happen if I connected them in series ( replacing the metal connector) for simplicity. Would this double the pressure. Physics not my strong point, though I have got the hang of the wheel and the lever.  Any thoughts appreciated. Roger V

Re: Electric fuel pump youd have to remove the pump take the pushrod out and either blank off the area with a plate or just refit the old pump
Bypass the pump, why would you want to double up the pumps?
you need to think how your wiring it you don't want the pump running constantly and ideally cuts out in the case of an accident

Re: Electric fuel pump Thanks Sean I'll remove the pushrod and replace the pump. That is a sensible idea regarding stopping pumping when the engine is not running. Off the oil pressure perhaps, though I am not sure how, as when i think about it, the oil switch is on the negative side. I wonder if they did it on the Mini and Morris Minor! Cheers

Re: Electric fuel pump Why not replace the old mechanical one, with a new mechanical one?
Then you keep it simple and tidy.

Re: Electric fuel pump Was only chatting in work yesterday about the SU electric fuel pump on my old Morris Minor Tourer sticking at the most inopportune times. Like in lane 3 on the motorway. Small mallet was part of my tool kit. A quick smack on the body of the pump would result in the points unsticking and clicking madly to draw fuel back up from the tank. Also had a tin of WD40 to spray on the points if they continued to stick.

Re: Electric fuel pump I'll make sure I locate in a suitable place where I can hit it with mallet then.

Re: Electric fuel pump PMSL! Just noticed the little quote at the bottom of your posts. Well I've just showed an electrical fault can be cured by a hammer.
