No, not too bad.  Per recommendations from this site, de-pressurize it first by disconnecting the pump connector under the tank, and cranking (or temporarily starting) the bike until it dies.  Then treat it like an air line fitting.  Comes off easy.  The pump and filter takes some patient jiggling to get out, but just take your time and don't force it.

Just to clarify, disconnect the ELECTRICAL wire connection under the tank then crank over a few times to depressurize.  Look for the disconnect downstream of the tank.  It's buried next to the frame.  Obviously the less gas in the tank the better.  I carried a spare bottle of gas and rode until I ran out.   Dumped in just enough to get me home on fumes.  Conveniently, I was 2 block from my garage.

Question: when you replace the fuel filter, do you replace the hoses? Or is there enough hose that you can cut the ends; or do you cut off the clamps?

you carefully pry open the old ones and reuse the same fuel line. it is special (read expensive) to spend it's life immersed in gas. buy new US built full circle clamps like shown above.

I've read somewhere.. :rolleyes: that these half plastic fuel filters are only rated for diesel fuel by the manufacturer. They *have* failed in places that has no alcohol in the fuel. Why would Guzzi use them? Well duh. They got a bargain on a car load of them, and will use them up. The more things change with Guzzi, the more they stay the same.  :grin: Gotta love em.

What he said about carefully removing them.  My filter from Guzzitech came with Oetiker clamps like the OEM.  I got a tool from amazon to crimp them on.  Nice.

2018 V7 III Carbon Shine 0921/1921 taken in for first check-up at MPH Cycles Inc. They checked and replaced 1/2 plastic fuel filter for me.

Thank you for keeping this info out there. I should not have a surprise issue!

2014 V7 Special - the 1/2 plastic fuel filter exploded at 123,000km (76,000 mi) - 270km after filling with an ethanol-enhanced fuel (by mistake, mis-read the sign on the bowser) if that means anything. Tow truck to the shed to change to an all metal one. Note that the fuel hose was fine, still in pristine condition, and so re-used.

Obviously, I will need to consider addressing this on my Milano.

I am curious about the current half and half filters being installed. Specifically, has the composition of the plastic changed which would lend itself to being immersed in fuel thus keeping it from degrading? Does anyone have any specific info regarding the filters in use today? I mean, it has been many years since this issue was first identified. 

Malik, what was the condition of yours when you changed it out? Had the plastic half become soft and pliable?

I suppose I will replace mine regardless since it is an inexpensive fix.

I replaced the fuel line on my Cali Vintge in 2007 after it popped off...

don't tell me that they're still putting that rubbish in the tanks??? Is the 2013 Griso affected?

The metal/plastic fuel filter has been used by Guzzi for many years.  I suspect it is present in all the fuel injected models.  My memory is weak but I seem to recall my Cali EV having one...that goes back to about 1995.  My Norge, Stelvio, and V7 all had metal/plastic.  Pete Roper probably has more accurate info.

Peter Y.

EV's came out in '98.  Not sure on the gas filter on EV's.  Previous model Cali would have the fuel filters outside the gas tank.  My '97 Cali1100i had the gas filter on the outside of the tank and I could get parts from NAPA.  My V11 Sports have external gas filters.

FWIW, I replaced the metal housed internal tank filter on on my '03 V11 Lemans last Spring with a new metal housed filter from Cadre Cycle.  At the same time, I replaced the internal flex hoses with similar (BMW) from Euro Moto Electrics.

The filter had swollen, then burst the seam. Looks like the pressure forced it apart. There was a lot of particles in the fuel that should not really be there, & unlikely to all be from the filter - sand, gravel, rubber bits, powder (when dried).  Once the filter was separated from the pump, it didn't take much for it to fall apart further.

Yep, looks like the older ones. The more things change the more they stay the same.
