Title: V9 fuel filter change
Post by: tris on January 19, 2023, 12:02:08 AM
I need to get a boroscope in the tank, but I suspect that my 17 plate V9 has the pesky plastic/metal filter  so needs replacing

Does anyone know the size of the hose clips needed please

Cheers

I used 3/8” Oetiker clamps from Menards in the plumbing aisle on mine.

My 17 had the pastic/metal filter from the factory.  It was quite bloated but still intact when I pulled it at about 3k.   Fairly straight forward, I watched a video on Youtube of the job being done on a v7, before starting, helped keep me out of trouble.

What's the deal with the plastic metal filter?

OK. So I have questions:

Is this a recall, or no?

If not: What's the replacement part number?

How long to replace?

I was concerned about the fuel filter on my 16 stornello when I had it after reading about it on this forum, never did replace it and had 20,000 miles on it when I traded it, maybe I got lucky ?

I've got a 2007 breva 750 that i went to the trouble of pulling the fuel pump out of the tank to find that it had a metal filter.
question is did it come that way or was it changed.  I bought the bike used so no way of knowing

No - it's a stupid error by Guzzi.

Search GuzziTechs site, they're based in the US and sell a complete kit

While you're there, hunt down the V7 filter change thread/video

There is no way to check if I have either filter. There's metal 3 inches from the fill cap preventing me from seeing anything.

You need a boroscope fella.

Run the tank low and CAREFULLY shove one of these in (https://amzn.eu/d/91egfRR ) for a shufti about

Tried to check mine but can't see diddly squat for the fuel at the moment.

Tris, if you know, no one has changed it since it left the factory, you can be 99.99% certain it’s plastic.

If you're willing to drain and remove the tank you can dismount the plate that holds the fuel pump and filter in the bottom of the tank.  A small inspection mirror will likely let you check the filter.  The misbehaving item is half plastic and half metal.  This method works on the V7III and I'd guess it will work on the V9 as well.

My 2019 V7 had the all metal filter.
Title: Re: V9 fuel filter change
Post by: Milosh on January 24, 2023, 03:44:35 PM
Thanks Jack Straw.

Has anyone heard of the filter failure that has left someone stranded?

My bike is still in winter storage and draining the whole tank is not something I'm looking forward to.
Title: Re: V9 fuel filter change
Post by: bad Chad on January 24, 2023, 06:35:56 PM
Yes, it has happened many, many times over many years.  It's hard to believe but Guzzi had know of this issue for several years and didn't address it.

That being said, I wouldn't be so concerned that I would drain a full tank.   Odd's are very very much in your favor that it is not going to fail in the next 100 miles of use.  Ride the v9 to on a full tank for until you hit 150 miles or so, then pop the tank off, much easier.

Being stranded is a scary thought !

I've got a 2016 V7 , and am planning a 4000 mile two week trip on it  this summer .

How many of those filters have failed ?

My bike is coming up on 30,000 miles  on it now and before spring Its getting an oil change , valves checked , and now checking the fuel filter .

How does the tank come off ?   :huh:

Sounds like you need a buddy with a bit more wrenching prowess than you possess, or find decent mechanical type and pay for the piece of mind?

I have plenty of mechanical experience. I fix scientific equipment Mon-Fri for a company called Waters and work in bicycle shop on Saturdays.

What I don't have is motorcycle mechanical experience.

Get a long piece of fuel line and a 5 gallon can. Use a old empty squeeze bottle with a cone shaped end. Stick the 1/2 squeezed bottle in the hose and release pressure an it will start to siphon the gas out. The rest is covered in the video. Except the swearing you will do!

Yup,
Been riding my 2017 Bobber now for too long without doing the change. Ordered the part from GuzziTech today. Will do the job this spring. Too darn cold to work out in the garage now.

Question for anyone who has done the change out. Is there is a gasket or o-ring need for the fuel filter assembly base plate? I have looked at the parts lists and dont see one listed. What is used to seal this item?

..... and if you're told that the UFI is a straight swap look at this


(https://i.ibb.co/1v18P2f/20230204-111726.jpg) (https://ibb.co/1v18P2f)


It's about 8mm fatter than the metal part on the old filter.

I guess it will fit, but it isn't going to help shoving it all back in.

I'll find a genuine one

Fuel filter  - she is changed :cool:

Observations for those that follow
When it won't come out keep wriggling and twisting and suddenly it will pop out.
Some fuel pipe connection pliers make it easier to disconnect the fuel connector. The cheap and nasty ones on Ebay that come in a set of 3 do the job - you need the red ones
The KL145 (and the UFI equivalent) is about 5mm bigger in diameter than what you are changing. This means that you cannot reuse the old tie wrap unless it was installed leaving a long tail
When it won't go in, keep wriggling and twisting and suddenly it will pop in - see above :wink:

Thanks for the help everyone

Tris what is involved in removing the tank from the bike? I am sure its not a big deal but hearing from some one who has just done it could be helpful.
Thanks Moto

It's not hard MG5
Obvious 10mm bolt at the back then lift wiggle and pull to rear should get it clear of the bungs at the front.
Watch that you don't bang the tank on the head stock and tank will now be loose .
From LH side of bike lift and tilt tank away from you and underneath you'll find a rubber breather hose pull that free.
With that disconnected you have space to move the tank a bit more
Possibly worth protecting RH cylinder head now and/or get a glamorous assistant to make sure that you don't loose control and whack tank on cylinder head

Disconnect fuel quick release by squeezing the 2 white buttons either side and pull to front
You now have room to follow the wiring to the plug, mine was tucked in under the top tube.

Install is the opposite of disassembly,  just make sure you get a positive click from the quick release

HTH

I have been dreading doing this to my 2016 Stone, but finally decided it should be done so get with it. Pleasant surprise was that start to finish it took me one hour. I used 3/8 oetiker fuel line clamps and reused the original plastic tie.

Thanks for the input. Been chomping at the bit to get this done on my 17' Bobber. I have a full gas tank on board right now and have been waiting to get it out to run it down to do the filter change. March has been very uncooperative here in Nebraska. Get a few warm days with the roads clear and then get hit with temps in the teens and snow again. Hopefully I will be able get out next week to get it done. I have had the needed items laying on the bench for a month now.

I have zip ties in several lengths on hand so should not be an issue to replace the original. I was planning on cutting the old one off anyway.

Finally after seemingly endless delays due to weather and family stuff got the filter changed out today. No problems. Old filter swollen but no cracks.

About like most here said it would. Rode the gas tank as low as possible and then used a small siphon set up to get the rest. Hardest part was the wrestling match with the tank to get it off of the rubber mounts and back in place when I was done. Covering the cylinder heads with a couple of small rugs kept from dinging up the tank while disconnecting the fuel line and electrical connector. The fuel pump set came out of the the tank with some messing around but went back in easily.

Bungs at the front? The diagram (from the Service Manual) has two M8 screws shown at the middle that are Philips head and impossible to get to.
Title: Re: V9 fuel filter change
Post by: tris on August 02, 2023, 11:44:04 AM
Yep

I've double checked the parts diagram and bungs are bolted to the frame on my V9

Tank is held on by the pockets in the tank around the bungs and the bolt at the back.

IIRC all 3 of my Guzzis have been the same
