Petcock Filter

[whenpigsfly514]

So how important is that 4'' orange filter thing? Mine was all sorts of funky and I took it off and out an inline fuel filter. Am I ok? or is it used for flow or anything in particular?

Its the mfirst line defense for keepind crap out of the petcock..let alone the rest of the system. I would soak the old one in some simple green for a hr or so and rinse. Repeat till the filter is as clean as you can get it and put it back.

It is also the part that gives you a "Reserve" fuel supply in the tank.

Without that filter, you will need to make sure your riding shoes are also comfortable walking shoes. :-\\\

Also, the type of inline filter you install will make a difference. If you got it at the auto parts store, good luck.
You need a filter that is designed for a gravity-fed fuel system, so get a filter made for a lawn tractor.

The crap that was on the old one isnt coming off.. I did try to clean it. I ended up cleaning the petcock and put a cone in line filter. the biggest thing I am worried about is flow or pressure or anything like that.

How is that? When you turn the needle you can watch the ball valve move to different locations.

The fuel pickup tubes (RES vs ON) inside the filters are at different heights, By removing the filter you are not changing the fuel level at which gasoline will enter the petcock. By turning the petcock handle, you are just opening a channel in the petcock under those pickup tubes.

I don't have a picture handy...

 

[Steve]

Those "different locations" are the inputs to the petcock. The "filter thing" is actually two tubes of different heights that determines the source for the fuel.

The "main" part of the input that feeds the "RUN" part of the petcock feeds from the upper tube, which leaves about 3" of fuel in the bottom of the tank.
When you move the petcock to "REServe" or "PRIme", it draws from the lower input at the bottom of the tank.

so what your saying is that I will be drawing fuel from the bottom at all times..

Here is my main concern, Am I going to destroy anything with out it?

 

[BigD_83]

Well,

you MIGHT not destroy anything, but if you have ANY crapola in your tank (e.g. rust) it will definitely make it's way into your petcock, and will eventually cause it to seize. One of the other things about the filter is that it shifts the draw off point higher in the tank, so heavier material (and water) settles out below the pickup tubes, greatly minimizing the amount of material that can flow into the petcock.

You really do want to have the filter in place.

Here's a picture. Not the petcock on your model, but it gives the idea of what is happening with the fuel tubes:

Just place an add in the PARTS WANTED SECTION and someone will have an old junk petcock layingb around that they can strip the periscope oput of for you.

Its not rocket science or an unobtainable part. Bet a fast Ebay search will bring up many of them.

 

[chuck hahn]

Heres a petcock cheap enought to be a donor for parts....


Many others of variuos models for cheap that can be used as donors.

Please get a new filter or clean yours. 24hrs in simple green or purple power WILL clean it.

We don't want to use this:

 

[chuck hahn]

Yes it will clean it..may not be pearly like new white, but the micro holes will be clean and the filter will again aloow FILTERTED fuel to flow freely.

Yes.

Your carbs will clog with debree from the tank or the fuel out of the gas pump. If they don't flood out from debree stuck in the needle and seat, the jets will eventually clog and run lean enough to do damage.

Needle clogged shortly after i started the bike for the first time cause of this an inline gravity filter has prevented recurrance.

Usually a second filter causes problems.

I've found with mine Its use one filter in the tank or one outside but not both.

Its a pain when the needles clog up.

 

[Gonzo]

I've got an old petcock in the garage you can have the tube off of. The valve portion is bent and leaking, but the filter and tube are fine. Shoot a PM if you want it.

Running fine for me so far both petcock and the gravity filter are New tho . But TBH thats only a temp solution. I need to clean and coat my tank thats the real solution.
