I changed the filter on the Racor RK 12963 fuel/water separator today. I try to do by the manual . I turn the ignition on. The green light was on the control panel. Back in the engine compartment. When I push the air purge button the lights went out in just a few seconds and nothing. I was holding in on the schrader valve at the same time and nothing. I repeated this about 4 to 5 time with no luck. I don't think that it's pumping like it should. I did get it started. My question is has any one had to replaced it? With what? And will it pressurizing the fuel system like this one should do. I think there is a more updated one out there since they superceded the filter with a newer one and a retrofit kit. part #1-PK12963

I recently installed a Racor 790R30 with integrated pump. Was able to prime the filters installed dry.

Gives me peace of mind if I happened to run out of fuel on the road.

On a recommendation from Mike Cantor, we replaced the original fuel system with the Raycor unit mainly because of the failure rate of the original ones.

I installed the same 790R30 on our 1994 Signature.

I believe our 2005 Signature had the 790R30 as original equipment as the control box was there, but the filter housing did not have a pump integrated.

The 790r30 was a simple plug and play re-installation.

I also installed shutoff valves in the fuel lines to eliminate any fuel running out of the lines or draining back to the tank when changing the filter.
