Pump dying?

[leman_opc]

Richard, would appreciate your advice on the iunstable flow issue I'm having once gain after several month normal operation.

The kit works normally in SYS mode, with the FDC jumper linked FIDC is also shown correctly on the bar gauge.

With the pump constantly on (pulled the socket from 30a relay and linked +12v feed to the pump) the flow is stable as it should be. With the pump connected via the relay the flow is OK for some short period and then gets unstable again (mostly underflowing).

Is my pump dying again or maybe any other ideas on what I should check before replacing? Is there a chance to get an "outdoor" version of the pump on special order (mine is located under front bumper so water / dirt are an issue).
