Today i fitted my electrical fuel pump with safety relay
this pumpthis safety relayseems to work fine, mounted the pump on the back fireboard of my 1.6 Murena. Can hear some clicking have to install noise absorbers.
Safety relay turns on the pump for 3 sec if i switch to contact. It senses the signal from the tacho at shuts off when the engine stops.
Did not drive around with this setup, it seems to work fine for what i've seen so far.
