Lotus Elan and Lotus Elan Plus 2 Forums

Well, personally, I find the Facet hammering cube to be very obnoxious in sprite's and midgets. Perhaps on an Elan they are not but it would seem that it would take Harley exhaust noise to drown one out. I have recently fitted a couple of Airtex 110-8251 pumps cheifly because they were cheap. I believe I bought them for around $37 on Amazon if memory serves. Not too noisy and, so far, reliable.

I have bought this little setup. It's a new Facet pump.Solid state and quite quiet (I'm told). Onto the facet pump I have directly fixed the small (also facet) regulator using a 1/8" bsp male / male nipple.. Quite compact. The pump delivers high flow but low pressure (Max 4Lb/sq") and the regulator is settable in .5Lb/sq" increments.

I just hope it works as good as it looks. One of my mates fitted a Facet Cube Pump to his classic recently and it is a very noisy little bit of Kit. This was one of the main reasons I did not want to fit one. I am killing two birds with one stone now. The STD pump has a small oil leak and I should no longer need the primer bulb in the boot to refill the carbs after long layups.

The pump / reg unit will be going into the same place as John has used. Ideal. I could just fit below the boot floorboard as I dont carry a spare wheel. Whichever is the easiest methinks. But the right hand side of the tank looks favorite to me.

Alex..

This is how I did it back in 1997, I like having the space to the side of the tank open to store liquids, a gallon jug with water and more will fit there and for us that sit on the left hand side to drive it puts a bit of weight on the opposite side. My Elan leaks, I carry fluids with me and there are some good locations where they don't tip and spill. The trough in front of the muffler is a pretty useless space and the facet fit there nicely, the fuel filter is just where it needed to be. Maybe it should have been before the pump but I have only cleaned it once in that time and there was very little crud in it. The Spyder fuel tank has the outlet on the side and that dictated much of the install. You work with what you have and make the best of it. Cost also comes into play most of the time, I was working when I built this Elan and back then it didn't so much. Oh, I meant to add the tire is 20 inches in diameter so there is a fair bit of extra space.

Alex, I had one of the round Facet's like you're fitting on an old pick-up. Considerably quieter than the cube type. Unfortunately, I fitted it to a Sprite that was still positive ground and forgot to take polarity into account. No more pump! So be careful of polarity!

Kurt.

Yes. Point taken but polarity is ok.. Neg earth only.

Thanks for the heads up though..

Thinking of installing an electric pump as well, what do you normally do at the carb end of the car, can you leave in the existing standard pump or do you have to bypass it.

I removed my standard pump completely. Here (or similar) is what you need to block the opening in the engine:

You can get a blanking plate for the mech fuel pump opening from BurtonPower.

Me being me and having some nice hard ally plate available I am going to make a blanking plate. The gasket should make a good template.

Merry Christmas guys.

Also used the Facet cube pump. Mine is an Elan Plus 2, so the mounting location is a bit different and external to the trunk (the tank outlet is outside the trunk).

The stock mechanical pump was removed and a correctly sized steel blanking plate installed by the PO. The electric pump is much quieter after revising the mounting using rubber grommets in the drilled holes and rubber bungs between the pump mounting flange and the fibreglass. It was very loud when mounted directly to the fibreglass (by the PO).

I located the filter under the bonnet, but this doesn't work too well. I can see an air bubble in the filter all the time and the car can be difficult to start after sitting. which kind of defeats the whole point of the modification. Once started it works fine, but the bubble is always there. I am going to move the filter to the pump mounting location like you guys have done. Looks like the filter can be attached directly to the pump nipples with threaded connections.

Here are a couple of links I found helpful. The correct pump is readily available from lots of suppliers. The one supplied by Moss Motors works well on my car. As there are so many models listed by Facet I just got mine from Moss.

Yes Alex,

this surely has to be one of the easiest Elan parts to BoDgE !
a bit of ally plate, a saw,file & a drill for the those 2 holes.
Easy 'innit!

Merry Xmas

I have left the mechanical pump in place as sort of a belt and suspenders approach to the problem and the mechanical pump functions as sort of a pressure control and feeds the carbs more as the revs rise. I've had it like this for over 10,000 miles and it works perfectly so no need to blank it off if you choose not to IMHO.

Leaving my one in place defeats half of my two birds with one stone idea. I would have to buy &fit a new one or fix the oil leak. Blanking plate methinks.
Nothing wrong with the idea but why bother to fit the lecy pump if the std fit unit works fine??

AB.....

We use the Facet's in our rally escorts, great pumps but noisy especially when mounted directly on the bodywork.
For the lotus I used a Hugo pump, it can handle the flow for the twin 40's and they make a lot less noise.

I have a mechanical fuel pump on both my Caterham Xflow and on my Elan. What is exactly the benefit of going electric? I don't get it?
