Cock filter ,Where?

Recommended Posts

I am looking at the scheduled maintenance table. Says Fuel tank,cock filter, piping. Check and adjust at 6,12K . What and where?. Something I should watch? Cheer!!

Is that in the maintenance schedule? I never noticed it.

For the early V11s the petcock filter is a screen attached to the petcock.

Here is an image of a typical petcock and its filter:

To clean drain fuel and remove petcock.

Beware of reverse threads.

There is also a large fuel filter that needs periodic changing.

The schedule for its replacement is debateble.

Hoses do dry out and need regular replacement.

If needed, be sure to replace with proper rated fuel lines.

I removed my petcock once and there were lots of stuff in the screen. Sorry for hijacking this thread but as Dave just answered the questions and it is related:

 

My fuel lines are braided and I guess OEM, ie. over 10 years old. I don't have any problems with them yet but the fact they are braided will effectively stop me from inspecting their health until too late. What are your opinions on this? I'm thinking of replacing them with non-braided. Pros and cons?

I get a gas line leak if I don't replace all the high pressure fuel lines every two years or so.

The line going from tank to pump seems to last longer.

The first time I changed the fuel filter I only replaced the lines between pump and filter, since it is under the most pressure.

But I got leaks where the lines connected to the fuel injectors. So, I replaced all the lines.

The next time I changed the fuel filter the hoses looked fine so I only replaced the ones that were easy to access. A few months later, the one I did not replace leaked.

I made the mistake of getting under rated fuel line, which could be the reason I was getting leaks after only a year or two. :homer:

Now I make sure I get the hose of the proper rating. I am not sure if it is making a difference yet....

SAE 30R7 is under rated except for between petcock and pump.

SAE 30R9 is the proper rating for un-submerged fuel lines.

SAE 30R10 is the proper rating for submerged fuel lines.

As for stainless steel braiding, I think what came with the bike is mostly cosmetic, and I don't think it will help unless your hose rests against a hot part of the engine. But you may find fuel line with steel braiding that will increase the pressure rating. That might not be a bad idea. :huh2:
