MV Agusta F4 1000's and Brutale 910's fuel line connector issue:

For owners wishing to replace the standard plastic connectors with replacement metal pieces. The fuel lines on these later bikes have been changed by MV to the PVC lined inner tube. The size and diameter of the fuel connector inserts are still the same as the ones used on the F4 750 and Brutale 750. However the removal and assembly methods are completely different and a little more complicated.

The prime issue is getting the original plastic connector off the fuel line, this is particularly hard and requires a great deal of care not to damage the fuel lines. Since the connectors are seated inside the PVC inner sleeve which does not expand as the outer rubber sleeve.

Regrettably the only way to do this is to cut part of the fuel line thus shortening the fuel line by the minimum length you can get away with (about 1cm); in order to remove the plastic connector.

Once those are removed to install a new fitting heat the tube with a heat gun on the lowest setting, taking great care not to melt the outer rubber tube, and while doing that widening both the inner and outer layers with a pair of sharp nose pliers until the new fitting can be inserted again - take care not to overdo the widening.

Once the above is completed a jubilee clip should be fitted on the fuel line prior to finally inserting the metal fuel connector.

Some photos attached.

Cool !

For those around the world without a heat gun, would the "old" trick of dipping the hose into a cup of boiling water for a minute or so still work with this new tube ? Then inserting the metal fitting ? Just wondering out loud :)


PS....& maybe it's the way to remove the plastic fitting too. If someone gets a chance to try it before they cut. Just a thought.

Just use a little bit of dish washing detergent on the tips. The connector will slide right in.

not sure if the boiling water will work, never tried it myself, but heat guns are pretty cheap to own and very useful to have around. http://www.amazon.com/gp/browse/?node=554570&lposid=u7-9784203-6,C,1655

Not really, I believe the issue is that the newer bikes have a tubing with a hard liner (to off-gas less), and the hose won't expand without some heat.
