Moto Guzzi V11 Bassa Fuel Filter
Change - Replacement
By Rich Arimoto
As noted by several others on the list,
changing the fuel filter on a Bassa (I expect on an V11EV or Jackal,
too) is a bit of a pita, and I thought I'd pass along several tips in
the interest of minimizing others' pain. Taking everything apart is a
little tedious but not too bad. Here's what I suggest (but don't hold
me responsible if I've forgotten anything!):
1. Disconnect the hose that runs from the fuel
pump to the fuel petcock; loosen the Allen screw that holds the tank
to the frame; then lift the tank slightly then disconnect the two
electrical plugs on the left hand side underneath the tank (one
should be marked with red -- this will help you make sure the plugs are properly
matched when you put everything back together). Next, take off
the skinny tube under the middle of the tank, then the front
vent hose, and finally the hose on the left hand side going from
the fuel filter to the tank (it has to be removed at the fuel
2. After you remove the tank, make a
mental note of where the front fitting of the fuel filter is
relative to the metal brake line and the inlet for the air box.
This will help you on reassembly as it is a bit of a kluge with
all the hoses, wires, etc. under the tank.
3. Attach a fairly long hose to the
fuel filter (the outlet to the tank just disconnected), and put
the open end of the hose in a suitable gas collection container.
There is enough gas in the filter to make a mess after you
loosen the clamp that holds the filter to the frame and start
moving things around. Note: Always be careful when messing with
4. Remove the top of the air box. Cut any
tie-wraps that you need to gain access to the old filter.
Disconnect the two other hoses to the fuel filter and remove.
5. If you're using a Napa 3008, wrap several
layers of duct tape around it so that it will fit snugly in the
clamp. Replace the banjo fittings using new crush washers,
re-install the filter, and replace any tie wraps removed. Here's
where it is important to have the outlet
properly located -- otherwise you'll have a hard time
re-attaching the hose to the tank.
6. Replace the air filter if needed
and re-install the air box.
7. Reattach the hose from the tank to
the fuel filter first (I tried doing it last and had to take
everything apart and start over).
8. Connect the other two hoses to the
tank and then the electrical plugs.
9. Re-attach tank/frame Allen
screw. Here's a tip: spray the rubber tank bumpers with silicone to
help make the tank easier to get back on (and off the next
10. Replace the hose to the petcock.
Not a fun job, but do-able!
