Fuel Filter question
« on: April 16, 2019, 11:53:42 am »
My '11 C14 has 36k miles and runs great, never a hiccup. I'll be going around the country this summer, put on around 5,000 miles total. Should I replace my fuel filter now?
And if I do...once the filter is out, it looks like thirsty work to tear apart the fuel pump and replace the filter. Those $70 High Flow fuel pumps look tempting. Are they reliable? Anyone installed one of them?

I dont know about the aftermarket pump but I took the screen out of mine and cleaned it. Easy job if I remember right.

If you do not have any symptoms of fuel starvation you can use fuel injector cleaner and that will cut through the majority of the debris built up on the filter. My only caution would be to use the stuff just before you are due for an oil change, and use as much of the fuel that has been treated as possible before changing the oil because that stuff turns the motor oil into what looks like black water. Which is a good thing meaning that it IS working and breaking down deposits but it makes the oil a lousy lubricant.

I have a link to them in the COG site, tech area.
So far, I think 3 people have bought and used them, and so far no complaints.

But... the actual process to remove and install that pump, and filter, is no different than doing the filter itself... i.e., might as well just buy the filter, and install that, save the $$ on the pump, even tho it is a very low price, as there is no "less" work in doing the pump... it all comes apart the same to get the pump out, filter or no filter..

I'm doing mine this week, as a p/m thing... My local Kaw dealer has the OEM filters in stock (9 of them), so it's worth it to me not to play the waiting game ordering online... price on the OEM p/n 49019-0013 from my local shop is $13.. but that is the OEM filter, the HighFlow ones are an aftermarket manufacturer, and don't "look" quite as effective, I'm sure they do work, but they are $14 for 3 of them... I just hate removing the tank that often.

scroll to the bottom for those filters....

I haven't seen that happen with Techron, at least not on my vehicles.  I do agree to use it all up as quickly as possible, though.  I tend to try use it before a long trip so it gets burned through without sitting in the tank for weeks.

Do I need to replace the bolts or can I just apply some loctite and reuse them?

neither...
 simply inspect the seal to insure it's ok, and re-install the assembly with the bolts you took out.. you don't need to replace them, or re-apply any locking agents... trust me...
follow the torque for those bolts,(do not get crazy and over torque them),
Torque - Fuel Pump Bolts: 9.8 N·m (1.0 kgf·m, 89 in·lb)
in a "star pattern", not circular;  and all will be fine. (if I had any doubt, I would never tell you to do that... just saying, I ALWAYS play the safe card.)

I bought a slightly used fuel pump ages ago and took mine apart and replaced the filter....just because.  It wasn't that bad but it was crudded up.  I still have the spare pump sitting on the bench.  Will probably put it up for sale.  Now that I think about it some more I believe I did experience some fuel (I thought) hiccups.  Putting the new used pump on fixed those problems.

I experienced the fuel starvation symptom while on  a road trip, 500 miles from home. The engine would sputter on moderate acceleration. I stopped at the first service station I came to and put in a bottle of whatever fuel system cleaner they had and filled the tank with fuel. The issue went away and never returned. I did purchase and install the fuel filter when I got home. I kep a spare filter on hand but don't plan to use it until I have symtoms.

So in a nutshell, if I don’t have time to change out the filter until fall ( and the bike now runs flawlessly), I can dump in a bottle of Techron in it this weekend and not worry about the bike unexpectedly acting fuel starved in the middle of B.F. Egypt during my month long trip , right ?

Right. And you never have to change / clean the fuel filter if you use F.I. cleaner once every, say, 5 to 10K miles. The F.I. cleaner really does work and will clean the entire fuel system starting with the tank, pump and pump filter. But it will also actually clean the injectors as well as the combustion chamber and even the spark plus. If you wait until the longer end of that range, 10K miles, you will also notice that after cleaning the bike will run better, idle better and have better throttle response. Scout's honor, the stuff really does work.

Agreed.  I especially like Techron.  Using it every 5-10K miles or something very relatively cheap, certainly easy, and seems perfectly safe (as long as the concentration is right and it is not OVER used).  Just remember that the bottle is designed for something like 12 - 18 gal, not the 6 gal tank on the Concours, so use only half a bottle.  I am not sure using the whole bottle would be a good idea, ever (but I am curious what others think on that).

I have never had fuel starvation, but it will develop a rough idle and sometimes hesitation on initial throttle and that is my signal that it needs cleaning.  All fuels have cleaners in them, but nowhere near the level of using a cleaner-in-a-bottle.  After the treatment, everything is normal again for many months/tanks.

If you have never used fuel cleaner on a regular basis, it might take using it a few times before any issues are resolved.

There ARE some contaminates that will remain in the filter- usually particulate matter that no fuel additive or fuel cleaner will dissolve.  But it should take many, many years for that type of stuff to matter.  All modern fuel stations use filters on their pumps.  So unless you are getting some really bad and unfiltered gas from some shady places, I would imagine it shouldn't become a major issue.

I buy two bottles of Techrom once a year. One goes in my Van that has a 30 gallon tank. The other bottle is spit between my four bikes and the  mower. The KLX and the mower also get a dose of fuel stabilizer/ethanol antidote.

as my fellow colleagues have noted,, Techron is the bomb... It's the only thing I will pour into my tank as a "cleaner/preventer" for gummy gas...

I do use IsoHeet, regularly, when I think I have water issues... BUT, I never "mix" the 2 in the same tank, I make sure to get rid of water, with the IsoHeet, run the tank empty, and fill the tank with good fuel again, (I can get "pure"gasoline here), and then when the tank gets down below half, just on straight gas, do a refill, and dump a bottle of Techron in.. yes, I do a full bottle (but then I make sure to run that full tank out... just don't dump it in, and let it sit.. that does nothing good...hell, do we need an excuse for riding 230 miles, in a day?.. that's silly... go ride.."honey, I gotta go clean my fuel system, I'll be back in 6 hours (meaning really 3-1/2 hours...heheheheh)..."... "ok dear, have fun"...) Makes for stinky riding, as it does clean, and ends up as smelly exhaust... but it's goooood. Heaven help anyone that follows you on a ride..   ::)

I miss Chevron gasoline up here in Ohio, always loved using it down in Va., and would go out of my way to get it....

here in Ohio, I buy IsoHeet, and Techron, by the "box", at WallyWorld... much cheaper than buying a bottle here and there, and then, I always have it on hand...
