thinking of fitting an electric fuel pump

[phil n gayle]

Hi all,
I've had a few problems with standard mechanical fuel pumps (not lasting too long). I've replaced all the pipes and filter checked the carb etc, and was thinking of fitting an electric fuel pump. Has anyone done this and can they recommend it, also which one? the van is a 1984 petrol with a 2.1 engine fitted.

Hello

I recently installed a electric fuel pump as the mechanical one packed in. I bought a Facet SS501 after some research. This was for a 2l Aircooled so check that the spec is good for the 2.1l. It is a good idea to check/change all the fuel lines, I was horified with some of the things I found. Also make sure to fit a filter.

I bought it from Glencoe, service and delivery speed was great. http://www.fuelsystem.co.uk/web-facet.pdf" onclick="window.open(this.href);return false; Total cost including pump, 6mm staight union, mounting kit and delivery was £45.

cheers

I used a Facet Posiflow pump which only run at 2-3 psi rather than 4-5 psi of a standard Facet pump so there is no need of a separate pressure regulator. Mount the pump on the chassis rail behind the tank and preferably wire the pump through a cut off safety circuit. CB Rotary pumps also work well but are nearly twice the price of Facet pumps.

The mounting bracket is not strictly necessary but enabled mounting using existing holes in the chassis rail


A couple off simple safety circuits so the pump stops pumping in the event off an accident and the engine stops running. The connection to the starter is there to prime the carbs if you run out of fuel or the carbs are dry after a long lay up.

Nice little writeup bigherb! Maybe put it in the Wiki???

Might be nice to add an overide switch so if you run out of petrol, you can prime system. No idea how hard it would be to do.

No Problem

An override switch is not really necessary as the relay is connected to the starter exciter wire so the pump will prime when cranking the engine and an electric pump will fill the carbs much quicker than a mechanical pump.

Good point on how much more fuel they can move.

Thanks, will try and get this Wiki'ed ASAP. Not sure whu our Wiki Guru is... and I'm kinda dumb with some of these techie things.

This thread looks really useful and looking at replacing our mechanical fuel pump as I suspect it is the source of our recent woes on the M5 and for £45 probably worth doing anyway.

Question though, in terms the existing mechanical fuel pump once the new electrical one is fitted, can this be left 'in situ' and if so does anything need to be disconnected? Alternatively, should it be removed and covered with some kind of blanking plate....?

Many thanks,

Chris
