Thanks very much for that. I gather then that the fuel pumps are a weak point with the 990adv ... Earlier in my relationship I had a high rpm misfire that the dealer said was a blocked fuel filter and thus not warranty ... It cost me several hundred dollars and some perplexity at the time and thus money it took for the dealer to diagnose.
For the life of me I cannot understand why a vehicle of this nature has the pump and fuel filter hidden inside the fuel tank in such an unserviceable fashion ... Pain ...
