MG MGA - Mounting cube type facet pump
|Hi, has anyone mounted a Facet cube type fuel pump as a stand by pump in their MGA, if so where and how did you mount it.|
|Hi George, I wouldn't recommend it as a permanent fixture. I have one as a spare incase the S.U. pump fails, Repco sell them as a Repco branded pump. The mounting holes are in the same position as an S.U. so you can mount it on the original mounting behind the drivers seat a very easy installation with a couple of pieces of fuel hose to connect to the fuel lines & hose clamps. I think it produces a slightly higher pressure that causes the float chambers to overfill unless your carbies have been recently rebuilt and have had the seals and valves replaced. Also more annoyingly it has a very loud pumping action that does not stop when the ignition is on & can be heard when the engine is running. OK as an emergency spare but that's about it. check Barneys site for more info on them.|
|Quite a few people have fitted the spare Facet pump in-line with the other pump (in series) and with a separate switch to use if the other pump breaks down.
Apparently, it will allow the fuel to flow through it without it being switched on.
You can fit the pump in parallel if you prefer but the plumbing is then a little more complicated.
The easiest place to mount it would be somewhere on the heater shelf near to the fuel pipe.
I run a tubular facet pump instead of the SU pump and I fitted it on rubber mountings which significantly reduces the noise it makes.
( I have fitted a fuel pressure regulator to my car as I run a Weber carb and it floods easily with the pressure the Facet puts out)
I do carry a spare cube style Facet pump with a length of fuel pipe and clips in case I ever need one, but hopefully it will stay in its box.
|Thanks, mine would only be used if the SU failed,just good enough to get me home that's all.|
The problem is where and how to mount it, I would prefer it to be at the back close to the SU but there is not much room, I hadn't thought about putting it in the engine bay and really don't want to.
would like to hear from anyone with pic's that has put one down the back near the tank.
|George I fitted a Facet 35 years ago, I have never looked at it since it replaced the old SU! Certainly reliable. It is quiet (rubber mount) and the exhaust note takes over as soon as we get going! I hope it will continue to function, if not then it is a tow home. I can cope with that, I don't even carry a spare wheel! Relax, enjoy!|
|Bit like Barry. I have been running a Facet, but not the cube, for 20 years. Ticks loudly when the ignition is switched on but as soon as the engine fires I cannot hear it above all the other noises.|
My biggest problem was the high pressure delivery so I had to fit a pressure regulator to reduce it down to 1.5 psi from, I recall, about 4.5 psi.
Other than that it has never skipped a beat.
|Yes but where did you and how did you fit it|
I put it on the front face of the firewall just visible by the trunking. I have a detachable pressure gauge that screws into the unit.
|George, Mine is mounted in place of the old SU, using the same rubber and bracket. A short section of fuel hose to connect to existing in and outlet pipes.|
|In the topic "acceleration cut" I talked about the change of the fuel pump by a FACET. This pump delivers 96 l. per hour according to my own measurement taken just before the first carburetor. He left a photo of the installation.
|Yep that's what I wanted, thank you all for your input.|
Steve I was not sure about mounting it in the engine compartment I did not think it would pull fuel that far seeing how small it is, mine being 2.4 - 4 psi.
