Series 3 FFR Fuel Pump.

Hi All.
I am contemplating putting a 24 volt Fuel Pump on my 1984 109 FFR Petrol. I am having problems with the mechanical pump. It keeps draining back into the tanks. Would you recommend any perticular make or type and has anyone done this already.
Regards.
Chris.

Why not fit a one way valve instead? The float in the carb should hold enough to get the system primed, though.

Thanks for your reply. That had not occurred to me. However, I think I might gave a problem at the Change-over Valve. I got a strong smell of petrol in the Cab and when I checked the fuel lines I noticed that there was petrol under the valve. Checked the connections and all were tight.

Could it be air in the lines allowing it to seep back under gravity

I have a feeling that it is leaking at the valve. I am taking it off this evening to have a look.

When I was last searching for air leaks I placed some grease over joints as a check

I have connected the fuel pump to just 1 tank and it is running fine.
