What type of inline fuel filter to use?

[LonewalkerX]

Hello, I have a '79 GS550 and when I checked the petcock doesn't have a filter. So I was wondering what kind of inline fuel filter I should use. I've read somewhere that I should get one with a see through filter. What is wrong with using one such as this "
And also, do the old '79 550's have filters in their carbs like the newer ones? If you try to tell me to just replace the petcock then please at least tell me what kind I should get, a link to a specific one would be nice.
Thanks!

Here's the filter I was referring to.

I don't know what kind of GS550 you have, but here's a parts fiche for the '79 GS550E. Looks like it $87 and change, but there's a sale coming up after Thanksgiving where you could probably get it less.

I would get the right petcock and scrap the idea of an inline filter, you don't want dirt going through your petcock.

most of the outspoken ones here do not like filters, I have 2 gs 850 one has a filter and one does not, the one that does has a slightly rusted tank, so I have a filter on it. But I use automotive fuel line on it, with a fuel filter and stock thin walled fuel line it is easy to get a kink in it.

How does your bike with the filter run? Just the same as when it didn't have one?

Clean the tank if it's rusty. Tons of threads in the archives will provide guidance. A filter is a band aid, not a solution.

I've tried using inline filters and have had to taken them off. Wouldn't flow enough gas well enough to keep the bike from surging. Once I took them off everything was fine again. Keep the tank clean and inspect the screen on the petcock now and then.

If you need a filter get a 5/16" nipple gravity fed model. They are cone shaped and found in lawn mower sections. I found one at an Autozone once.

If it flows enough to have a steady stream coming out, it's enough to run the engine wide open. If later on it won't flow as much, replace it, it's done it's job.

Automotive filters need pump pressure to flow much fuel, they won't work.

Fixing the rusty tank is a better option.

The petcock includes a very good filter screen. Is this missing from yours for some reason?

[JEEPRUSTY]

Just musing but one of them nice Ford carb filters would make a hell of a high flow bike filter. I forget how big they actually though and they would require an adapter.
Just musing. Too much pressure required I imagine.

Please note that if your petcock does not have the filter screen on the inside of the tank, that also means that you don't have a RESERVE function, either.

That is, unless you still have the plastic tubes and the filter screen is messed up.

@bwringer:
Yeah, when I took the petcock apart, there was no filter in it. I'm guessing from one of the previous owners.

@Steve:
Yeah, I read about putting in a line to keep the reserve funtion, but I prefer keeping the tank above 1/4 no matter what.

did you take the petcock off the tank to take it apart? the filter is inside the tank, not in the petcock itself!

Sorry, I worded that wrong. What I meant was what you said; when I took the petcock off the gas tank there was no filter attached.
