Fuel Return Hose

[Mc tool]

huh, learn sommat every day . Mine has no jet in the return line and when I got the two ( return line and vent ) mixed up , I only knew as it pissed fuel everywhere when I filled the tank.
As a matter of interest , my paso 906 has a rotory vane type of electric pump , not a reciprocating one as I have been led to believe it would of had originally , and I just lenghtened the return line till I had sufficient pressure at the carb ( no idea what it is )

Thankyou to all who have quickly come forward with helpful advice. I fitted new hoses, checked that the restrictor was in place (it was), plumbed it all up correctly and it works. I can only assume that the float valve was somehow jammed closed initially.

However, all is well and it bursts into life as soon as I touch the starter button

Thanks again to all who helped

Cheers, CB

way to many gas fumes bet you blow your clutch out with air as well,Don't you


No Higgy, i don't blow out the clutch with an airline as even though asbestos hasn't been used for years i more than most are aware of the dangers of such an act, my Father died of mesothelioma.

My granddad died of cancer too . after having his lip , tounge , soft pallet and most of his throat removed in various opps , he had a hole put in his wind pipe so he could stick his fag in there and keep smoking talk about dedication

I tested fuel pressure at the carb on my 906 without any jet restrictor in the return line and it read 1.8psi. Actually the Weber carb runs okay at 1.8psi. However, if if Ducati general carb pressure is 2.5 - 3psi then it explains the restrictor on the 906 return line, or the other way to get the pressure up at the carb is by fitting a Holley fuel pressure regulator.

If you look at the manuals for the 750 and the 906 you can see they have a different return line system, and you can envisage how the 750 has more pressure with the way the return line is set up (so 750 owners talk about fitting regulators to reduce pressure down to 2.5 - 3 psi.

So, to get to 2.5 - 3psi at the carb 750s needed a regulator to bring it down to that and the 906, with different return line system needs a retrictor in the return line or a regulator to bring it up. But on a 906 it is a choice because 1.8psi still works.
