Topic: Inline fuel filters

[Johnny5]

I have one of these filters installed. Just curious if they are effective enough to keep my slow jets clear?

I ask because I've always had one installed, and the slow jet on the 2nd carb was clogged after a good cleaning after my third short ride.

If the filters do a good job, then I must have missed a section on that carb when I cleaned them. The other three slow jets were clear.

I run the same filter on my 650. the last time I pulled the carbs I found an alarming amount of crap in my bowls, no clogging, yet. I will be changing to a larger paper element soon.

+1 on crap in bowls with this type of filter. I think paper filter element is the way to go...

Sounds like I'll be changing also.

Thanks,

I got a filter 1/4" from autozone...last time I took my carbs off...it was spot clean...not a single grain of dirtyness...paper filters are the best in my opionion

Thanks for the heads up, I'll go for the paper from now on.

Do you remember the brand/model?

[Johnny5]

I'd like to know too. I went there today and could only find a large filter for 1/4".

Got mine at the John Deere tractor shop. They seem to work OK. I think the element is paper

You have several threads going about fuel and carb issues..............they are all inter-related.  #1.......If you have a dirty tank.......fix it.  A good radiator shop that also fixes gas-tanks can clean the tank, pressure test it, and install a modern liner that will withstand ethanol for less than $100.  I live in the land of the cheap and pay less than $50 including pin-hole repair. 

The fuel filters slow the flow and impede the carbs from performing at their best under all throttle conditions.  When the filter is doing its job, it loses flow capacity over time.  #2......The fuel line ID must be the same as stock or the bowl filling rate will be wrong.  Your high idle could be caused by a temporary vacuum in the bowls that will cause the available fuel to be sucked into the main jet until enough fuel gets to the bowl.

The float bowl vents prevent any of this from happening or becoming a problem.  Also, even with an in-line filter, the maximum fuel flow rate is much more than the carbs could ever use even at the fastest speeds.  Sure a clogged filter would impede the flow of gas, but so would a clogged petcock filter or screen. 

I've said it before and I'll keep saying it whenever necessary:  An in-line fuel filter, if fitted properly and installed on properly routed fuel lines will cause zero problems with fuel delivery.

From my other thread, everything is clean, carbs, new filter, and tank. My issue with the revving is happening in neutral as well as at speed. Plus, I've used these inline filters forever without seeing this issue. Im sure it's the carbs out of sync. Will report later on tonight.

Shhhh! Don't speak too loud or you'll wake Two Tired up and he'll notice this thread too
