Just did mine today but fitted the 400 LPH Walbro pump inside the standard bucket Because it is that much bigger it was a bit of a mission reshaping the bucket removing all the ribbing around the return pipes for the filter, I then in the end put the standard filter back on the walbro pump with the clips removed. The one that came with the 400 lph pump just wouldnt fit inside the canister. I think if I do it again I will just buy a 400 LPH pump and larger canister, will see how this one performs. (Im watching AFR closely).. The BF had the bayonet clip in fittings instead of the screws and also just cut the factory wires off at the pump ends and soldered the spade terminals on directly to these wires, grey to +ve black to -ve no problems. , did the 360 loop in the fuel line so plenty of movement there actually better movement now than factory one... the fuel lines strangely enough only had a in and out no line for a carbon canister return,... found those clips easy to undo just light pressure with tiny screwdriver in the end next to the white pipe across three of the sides came awat easy as. and positve clip back on. .
