Cheers Miti-babe for the info on using a different relay, the Vf seems to be running ok now, well chuffed[:D] while letting the bike tickover I can get my hand under the LH side panel to feel the pump pulsing at approx 40-45 pulses per minute, when I turn the supply off at the tap the pump will start to speed up as it fights for fuel and then slows back down again when the supply is turned back on and pressure builds up, I did this for my reassurance for when I take the bike out, Phil.
