Like it says  - if you've fitted an electric pump to your beta where did it go?

I'm struggling a little to see a good spot for it other than actually in the boot.

Normally it would for on the rear crossmember,
You should find three small holes on the right
side, next to the headlights auto-adjust system.

I was thinking more of an aftermrket pump like a Facet for twin 40s.

I'll have a look though.

You'll need to check, some facet pumps
are pull so ok for engine bay, some are
push and need to be below tank.

If it is a Facet interruptor type (cylindrical silvertop redtop etc) then it is a push type that should be near the tank. Put a large filter in line first and check the tank does not have crud waiting to kill your nice new pump! There is a very fine filter in the pump, but that is last defense and will clog quickly if you have any sediment in the tank (guess how I know).

You can run them bolted to the area in front of the front suspension turret but they are working harder and the risk of vapour lock from hot fuel is higher.
If you are thinking of big horsepower later buy the right pump now typically Silvertop Competition the specs are all on the Fuel Systems Enterprises website.

PS remember the pressure regulator set to 3 PSI if it is a Filter king this provides a handy little reserve of fuel in the engine bay for starting and a bit more protection for those fine drillings and jets in the carb(s).

The last one I tried in the engine bay was a solid state  - not a great success TBH it struggled even with the standard carb.

The tank has been out and thouroughly cleaned (in and out) to sort out all my fuel starvation / blockage issues when I first ran the car and it wouldn't do more than mile before packing up! I've also got a fabricated aluminium tank that I can fit if I need to.

So the plan is an interrupter type near the tank - but I'm not sure where best to fit it at the moment. I'd like to be able to get to it if I need to but I'm not keen on it being in the boot.

I'm not keen on it being in the boot.

Why? I have a Facet electric pump for my Guy Croft engined Fiat 131 and it's the boot just above the tank.



Other 131s I've seen with twin 40s or 45s also use electric pumps and most of them are in the same location in the boot as mine.

Personal preference - I don't like fuel being inside the car even if it is in the boot.  I prefer to have it all underneath.

Hence the question of where it could fit.

In the 131 at least, the tank is in the boot and the fuel lines run inside the car to the engine (and back to the tank).
I do have an inertia switch fitted....

I didn't know that.

If I do have to fit it in the boot I'll probably enclose it somehow and certainly an inertia switch or oil pressure switch would have to be part of the installation.

I fitted mine to the rear crossmember, it is a Walbro pump very similar in size to the facet one. (same mountings) It is mounted horizontally not sure if you can do that with the Facet one.  I am using a Holley type fuel pressure reg mounted in the engine bay. Having the pump as low as possible reduces any problems with air locks on the pump inlet.

I fitted a relay via the oil pressure switch so the pump stops wren the oil light comes on, and used an HPE rear window wiper momentary switch as an override to prime the pump and build pressure before starting.

Can make up a wiring diagram if you need one.

I fitted on top in between the crossmember and the body - a but if a tight fit, I'll take a photo when I get chance.

Hi Stuart

Here is the pic but probably no use to you if you are using a Facet pump. Thi is a Walbro pump and the outlet is in the end.

Just athought (and not much use if you've already bought a Facet Silver Top), but I've used a Huco fuel pump on my Spider for the last 4 or 5 years and it's been fine. It's a 'pull' rather than 'push' pump, so lives in the engine bay (mine is on the front cross member behind the bumper), making installation MUCH easier. It's suitable for 'fast road cars' and delivers up to 120 litres per hour, and is a direct replacement for old SU type pumps.

I have got a Huco pump myself - it wasn't up to much under the bonnet but it might well work better down by the tank. Have you blanked off the return fuel line?

Yes, I blanked the return line off as per instructions. In fairness, my motor is entirely standard and so the Huco can deal easily with its quite modest demands. Yours is (I believe) substantially modified, and I'm not sure the Huco was designed to cope with that. I notice that the Huco blurb doesn't specify a power output it can service...
