Faccet type pump operation

[Dougal]

Hi Chaps, I have just installed a facet type pump to replace the dead SU I found on in situe and the leaking mechanical pump that was in use.

Its all good no leaks and fuel coming through. However I was expecting the pump to stop when it fills the float bowls and gets up to pressure.

Does this kind of pump work differently to the SU's and just keep pumping away?

Yes, they just keep pumping away. Annoying but normal.

Mine just kept on pumping all the time. Then it slowly gave up after about 3 years and 6000 miles.

Cheers guys I guess there had to be a downside, still at the price difference I guess I could install a few more as backups.

Anyone installed a pressure sensor in the fuel line?

I still think buying a New S.U fuel pump as a replacement is cheaper in the long run! They last many years at least mine did! However the facet is great for a backup just in case! I am now installing my facet with a 3 way switch and fuse in a handy location so i can switch over on the fly if i have to!

I hooked two of these up and have a switch that turns either on in case of trouble.

I had installed the facet on my other car and got caught on a road when it died. Getting to that pump is difficult without a floor jack.
So my BJ8 has two and I run them both occasionally and never have to worry about losing fuel pressure now.

Moss Motors has a good video explaining these pumps and the original SUs. Bob

It's funny - when I first resored my 100 in the early 80's I installed one of these pumps and it sounded just like an SU. It would click until the carb bowls filled uo and then it would stop. I put a new one in (just for the heck of it) about 10 years ago, keeping the old one as a spare. It clicks continuously.

I liked the old one better - I may swap it back in.

I've been running one of these for 10 years. Pegasus Auto Racing sells a rubber mount kit which makes them quieter.

Am very surprised to hear one failed. I've heard they last for decades.

The Facet pump mounts nicely on an MGB gearbox mount Moss no. 413-050 ( $5) and will quiet it down quite a bit. I prefer an SU pump because I love the sound of them and for the most part are pretty reliable but have used Facet pumps in a pinch. The same pump is used on Onan and Generac RV generators and is available at NAPA stores for $40. They work best pushing fuel so you will have problems if you mount it too high in relation to the fuel in the tank.
