Non stock fuel pumps?

[Luke_Healey]

Here's another question about my '66 Sprite. The previous owner removed the SU fuel pump and put in a Carter carotor style pump that looks just like this:

I'm getting a reading of between 2.5PSI and 3.25PSI out of the thing up at the fuel line that leads to the carburetors.

Are these pumps OK, or are they known to be problematic? Are they even known? It looks like a FI pump, but it's low pressure. I'd never encountered one before.

On my previous Sprite, I was running a noisy little universal fuel pump that looked like this:

And it made the car run A-OK.


Opinions? I've always wondered about the Carter one. No real reason, other than I'd never heard of anyone running one. It sounds a lot quieter, like an in-tank pump you'd find on an FI car.

I had one of those carter pumps and it worked fine with the carbs, but failed rather quickly.

I run a FACET, I think. Looks just like the square thing above. When we picked it up they had two pressures available. the 1-> 4# and the 4-> 7#. I had just had my carbs rebuilt (Curto) and even with the low pressure one, gas would gush out the overflow on the top of the rear carb. I put on a Holley fuel pressure regulator... problem solved. I later added a pressure gauge so I can run ANY pressure pump that happens to be on the shelf at NAPA at the time that my pump fails--if ever. Easy, Simple, Not Cheap, but not too expensive for peace of mind. It made the 4000+ mile trip to Missouri and back last summer. .... Now to start getting it ready for the even longer trip to Elkhart Lake!!!!

I am running the Carter pump on 4 Sprites now.
I had one on a car I sold some years back too, it worked fine for 11 years when I sold the car.
The last couple I bought are now made in Mexico, we'll see if they last 11+ years.
I prefer the Carters over the square jobs just because they are sooooo much quieter.

I have a Bendix pump on my MGB thats been on there since the 70's. Before I got it was on a couple of other brit cars of friends. Facet now offers that pump. Its the round one with the domed top and a removable filter on the bottom. looks a little like a SU but is a little noisier. Nothing like the rattling cube of Facet's that everyone seems to like. Its been a good pump.

If you have the original SU pump, you can have it rebuilt with new electronic contactless innards by Dave Dubois at https://homepages.donobi.net/sufuelpumps/

From outside it'll look like a new SU pump, and it will tick in a reassuring dignified way, instead of the frantic chattering of the Facet pump.
