Title: Fitting elec. fuel pump
Post by: jreacock on March 06, 2017, 10:34:29 PM
Hi. I was wondering whether anyone has fitted a Facet fuel pump and Filter King to their Beta recently?
I'm just about to go through this process, but wouldn't mind any advice regarding the positioning of the pump and the filter, wiring-up etc. (does the loom have wiring for a pump?). I want to utilise the existing factory holes in the front bonnet bay for the filter (around the general coil area) - as I don't want to be drilling holes if I can possibly avoid it.
It's an 81 FL Spyder 2L.

Thanks for any advice.
Justin.

Hi

There has been some discussion of electric fuel pump wiring here, specifically safety related so in the case of an accident etc the pump is switched off, cannot remember the thread, so hopefully someone will either post the info or provide a link.

Hi Peter. Yes - I forgot to say that I'll be using an inertial cut-off switch - which I'll also mount somewhere in the engine bay area (or maybe the boot). It has a reset button on the top, and cuts off the power to the fuel pump if the unthinkable happens.

I asked Guy Croft about this, because he supplied it all, and I think he has pretty much answered the question. Here's the reply for anyone else who is thinking about doing this:

Mount the pump on the rubber mounts in the boot, run it off a relay activated by the ignition switch. Use cabling of similar gauge to the cable already fitted to the Facet pump - it does take quite a lot of current. Mount the pump no higher that you have to!

Mount the regulator and gauge adapter in the engine bay, gauge between regulator and carb. Remove the gauge and plug the adapter after calibrating the fuel pressure to 3.5psiwith ignition on but engine not running.
 


Cheers,
Justin.

Okay - I managed to fit the pump to the fuel filler pipe of all places, using exhaust clamp parts. It works really well - and meant no holes needed to be drilled anywhere. Just need to earth it, because of the rubber mounts.

I've got an inertia cut-off switch to connect in-line with it, but just wondered whether anyone has found a suitable wire to use in this neck of the woods? The manual mentions a fuel lift pump (not sure what that is), but I was hoping that there may have been something in the loom ready for a pump. Anyone got any experience with this? It would be great not to run additional wires if possible.
Thanks,
Justin.

I put the inertia cut off switch under the bonnet  - but that was all with retro fitted wiring. That  said the wires to the pump must start somewhere near the fuse box so I'd be tempted to located them and splice the switch into them.

I like the mounting idea. Never seen that before.

Me too - very neat idea. Must file that one away mentally for future use...

I realise I'm very late to comment on this but I wonder if that is really such a good idea.

There are, I think, two issues.

The first is that I think you may be underestimating the amount of noise generated by these when running. It really is quite loud. Mine  was mounted under the floor in the space adjacent to the fuel filler pipe of the tank. Even there and with rubber mounts it provided a continual background noise.

Secondly you have a system where pressurised fuel will effectively be brought into the passenger compartment and then lead out again . All you need is a quite minor leak and the boot carpets, rear seat panel and the seatbacks will be soaked with fuel or vapour and a serious fire might happen.

Attached is a rather poor photo of the installation I used. in addition there was an in line filter that was fitted in a 'U' shaped holder on the top of the rear cross member. This was in addition to the filter king regulator in the engine compartment.

Please reconsider this.
