Help oh Gurus of the fuel system

[BusaJim]

As some of you know I have been out of action for the last few years and the busa has been a nice looking decoration for the garage.

Over that last few day I have been replacing the hoses oil brake and clutch fluid. all was going fine with the odd well lot of expletives.

I try an start the bike but no go can you mixup the fuel line I know its a dumb question I can't even hear the fuel pump start.


Thanks in advance

Busajim or maybe I should call myself bugger it up jim

Oh and that to Bazman for the new exhaust what a legend I know Honda says it but yoiu do meet the nicest people how ride busa's

Jim I take it that it's a Gen I ? Have you used the genuine hose's for the fuel lines you replaced ? The layout is critical on the 99 er's even to the way one lays across the gear box and the other has to be indexed with marks so that it's not twisted when tank is lowered. Try and start it with tank raised .................. will isolate if hose routing is the culprit.
Just re read post jim .................. if you can't hear fuel pump when key on kill switch on ............... put test light on power supply at pump connector and identify if it has power, if not then check pump fuse. Also if it has been stored for a long time, check that rats, mice possums (and tassie devils) haven't been munching on any wires anywhere. Wouldn't be the first time. If still no go and you have power at the pump it may well have siezed up. Basically until you can hear pump activate it's pointless looking at fuel lines etc How long since bike was actually started ?

Jim, I've read on here in the past that a commodore fuel pump is either the same or will fit ,Someone else may know which model commy & if your lucky a part No .

You need to change the fuel system a little to swap to an aftermarket pump, bosch 070 or walbro 392 are both good efi pumps that are not too large, not sure how the reg mounts on the 99-00 so be aware you may need to change that to aftermarket too and do something with filters and hoses, if your not up for all the potential changes just get another std pump
or see if the oiginal one will clean out, sometimes it just needs a flush , or if your carefull about sparks a flush and reverse power the pump out of the bike

Thanks Maj,

I've heard about those on the American site could be an option it's soaking in some RP7 at the moment might do the trick but if not the ones you said could be a good project.

Let you know
