V7 Fuel Filter Not Replaceable?

I did a video on it yesterday... I'll pin this thread also.
Goes without saying best to run the fuel low or drain the tank as we did for the the video below.



Well after spending 2 hours of my time and a further 2 hours of the time of two of my mechanically minded friends I have concluded that the fuel filter is not replaceable. No matter what we do the unit cannot be removed from the tank, if we apply any more force things are most certainly going to break.

Now I am not surprised, as how can you remove a filer that is the size of the opening, and a pump that is the size of the opening that are connected together with lots of other fittings. If the hole is size 1 and the pieces are size 2.5, this does not work. I have decided that the filter/pump unit was installed on the bottom piece of the tank before it was welded together.

The good news is the filter is clean white and perfectly shaped, no bulging at all. Must because I feed her only 100% ethanol free fuel and nothing else.

When I take her in for her for her 6000 ish service I will ask them to replace the filter for me if they can.

What a horrible, stupidly designed system. This is what happens when a company lets the most junior designer/engineer design something they do not think will even need to be accessible.

Sounds like it is as bad as the system on some of the EV series bikes with the in tank pump and filter. It can come out and back in. It only goes one way so to speak and it takes a lot of wiggling and trial and error. No force should be used. It was wise to stop before you used force. Another 5mm or so of opening and it wouldn't be too bad of a job. I'm glad my in tank filter is a breeze to change on the 1100 Breva.

The service manual, Pg. 28 shows six bolts that installs the removable assembly. Is that what you are referring to?

The bolts come out easily. But he filter/pump init itself just will not come out no matter how I turn it, twist it, plead with it, cajole it or swear at it.

Interesting! And so if I take a new fuel pump and filter assembly i would not be able to insert it into the tank?

one time i had to replace a sportster fuel pump and filter- the ethanol had turned the plastic mesh into the cereal frosted wheats.it would crumble. I changed the entire thing. It was difficult getting it out also.

Can some of you post some photos of this process? On mine the fuel cap opening is welded, with the opening narrow for a gas pump nozzle. It's cage like, no idea how something would fit thru? The replacement fuel filter looks small enough in the store. And others have completed the job. Feel like I'm missing a step or great hint. https://drive.google.com/file/d/1u3Kj-I3TPGuk01B-kTQMLcbC4c49cPgdsw/view?usp=sharing

Haven't done it myself yet, but I was at the local shop when he did a fuel filter replacement. I wasn't watching all that closely but it seemed to be:

- drain tank
- disconnect fittings and electricals and remove from bike
- remove six bolts on the mounting plate inside the tank tunnel
- carefully remove pump and filter assembly with a bit of a half-twist on their mounting plate
- replace filter
- reinstall in reverse order

Took him about eight minutes with a helper. ??

After seeing one done it took me about 15mins to get mine out and after doing the switch about 10 to get it back in. There's a trick to it, I'm sure, but with me it was just wiggle and twist until it fell out.

That certainly sounds simple enough that any Joe could do it. Maybe I've misunderstood the location of the fuel filter. You mention the tank tunnel? In the drawing it appears to be under the tank, not inside? I was understanding it was inside the tank. I'm looking at the Service Station Manual page 27.

t's kinda like the reverse of building a model boat in a bottle. With a bit of effort, I was able to remove the pump and filter on my V7(I), but I could not get the assembly back into the tank unless I omitted the Zip tie that holds the filter against the pump. So, I installed it with the filter free to flop around. Not good practice, but it held up until I sold the bike. Having learned my lesson, I have not attempted to change the filter on my V7II. I'll take my chances that the filter will not develop a leak at the plastic/metal seam.

The fuel filter is inside the tank, attached to the fuel pump assembly. To get to it, you empty the tank, remove it from the motorcycle, and unbolt the access plate that holds the fuel pump assembly to the fuel tank. The plate is located inside the tunnel of the fuel tank what sits around the motorcycle frame.

This drawing, from the manual, shows the fuel pump assembly and how it fits into the tank's frame tunnel.

When you take the tank off and look into the tunnel, what you see is the oval access/mounting plate with the electrical and fuel connections on the outside. You unbolt that to get to the pump and filter assembly, which come off the tank with it.

Well it's all in the tank now, so it had to get in there somehow. Guzzi would not have manufactured the tank round the fuel pump/filter assembly.

I asked since you can always break the filter off to get it out, only if putting a new one back in.

Now that makes a lot more sense to me. For whatever reason I thought filter and pump had to come thru cap/nozzle. What can I say, I'm a newbie wrench. Thanks for information. I'm now confident I can complete this mini project.

6 bolts and a rubber seal is pretty easy. Just unplug line. The rest is self explanatory. It helps to run it out of fuel or pump it out.

Done my v7ii, and zip tie went on exactly where the old one was. Patience...

I ordered the new filter from Todd, and it is arriving today. I am not sure if I will get around to replacing it tonight, but I'll take pictures of the process and post them here so it can be a help to others. I have never done this before but it sounds easy enough to do.
