alternative for facet fuel pump carburated engine
Does anyone have any experience with other types of low pressure electric pumps? I'm trying to find an alternative to the facet pump. There seems to be a lot of failures. Mine included. Is anyone using a filter before the inlet to the pump?

Same pump since May of 1993, no problem. I do have filters ahead of the pump.

Mel, does your filter have AN fittings or is it rubber line and clamps? I was trying to stay away from rubber and use an fittings on everything.

I use rubber hoses with clamps. YMMV.

Does it look like this, or is it one of the "cube" types?

Be careful, some Facet pumps at auto parts houses contain a check valve to prevent fuel flow with the pump off. Check the spec sheet for the part numbers with correct fuel flow and no check valve:

it is a cube one, rattle pump. 4 to 6 psi I believe. I have a Van's replacement ready to go back in but I wanted to see if there was a better one out there.

I suspect that you hearing about 'a lot of failures' is a simple quantity measurement, and not a percentage measurement. When there are thousands (or hundreds of thousands, or millions) of a device in operation, there will be 'a lot' (in quantity) of failures. Failure *rate* is another matter entirely. And if you read carefully, it's fairly common for those who bothered to investigate their 'defective' pumps to discover that the only thing wrong with them was a piece of trash stuck in the pump (hardly the pump's fault).
Those pumps are actually designed for continuous duty in various non-aviation environments, so if fed clean gas, most will easily last the life of the airframe when used as a backup/boost pump.
Hey Sam, I might be wrong, but aren't you thinking about the PSO (positive shutoff) valve, and not the check valve? If I understand it correctly, the check valve shouldn't prevent flow with the pump off; it just prevents back-flow if you have a pair of pumps plumbed in parallel.

Yes I agree about the percentages, but there are more than a handful of failures documented on this site and only one could be disaster. I'd prefer to use another pump if there is another proven option available. Mine probably has trash in it too and I'll put filters before the fuel selector in both tank lines now and replace the pump.
