Fuel pump
Good morning all. I have a Cagiva 650 Raptor (SV 650 really) !!! The dreaded E10 fuel pretty much destroyed the original pump after winter storage. I sourced what on visual inspection looks like a really clean unit, but, once fitted it allows fuel to pass even before the power is connected. Does this mean the pump is at fault ? Or is it me being thick ?!!? The pump was purchased from E-bay, unfortunately the seller is away until 10/08/24, so obviously I cannot do much until then, regarding returns. Hoping some clever bugger can tell me either way, I'm fairly competent on the spanners, and do not think its me ! A new pump is the best part of £1k !

Re: Fuel pump
Yes I wouldnt have though fuel should run through as the drawing in the free online workshop manual shows a spring loaded non return valve in the outlet which should need some pressure to overcome before fuel comes out...

Re: Fuel pump
Check the US forum. There are several posts on rebuilding the pumps and or some of the cheaper Alternatives,
