Possible Napa fix for the spendy CFI fuel filter

[EricW]

Here's what I have put together so far. Warning: This is not ride tested yet, just parts on the bench that have possibilities. Here's the list:
Napa Gold # 3300 Fuel filter
Napa # 730-4926 Steel fuel like quick connect 5/16" (need 2 ea.)
Napa # 705-1226 High pressure hose clamps (need 4 ea.)
Napa bulk 5/16" high pressure fuel line (1 foot is plenty)

OEM and the Napa parts

Napa filter

5/16" quick connects

Clamps

The only problem I see is that once the quick connect is on the filter it is really tight to get the removal tool in. Might have to cut the nipple off the filter at change time then insert the removal tool.

Whaddya think???? EW

On a turbo setup like yours it shoud work. On a setup using the airbox I think it will be a tight fit between the belt guard and the airbox. For sure it will not fit in the holder on the airbox. Another issue is if the clamps will tighten enough to hold 60 lbs pressure and stay tight.

 

[EricW]

Good point on the airbox space. I haven't had an airbox for more than a day or so in 3 builds so I haven't really sized up the possibilities. I too am concerned about the clamps. Do you know of any higher quality ones? EW

This is what I did last year, worked just fine.

Again, on a turbo setup, no problem. Using the stock airbox I dont see that big of a filter fitting.

Dave you could do it..you would need to move the filter over some so it sets up on the clutch cover I think to have enough room for it..or behind the airbox(between the airbox and the tank)...I would have my local hydraulic hose shop silver soilder An fittings to the female ends and use braided teflon hose on it...I bet it would cost less then the stock filter and last the life of the sled with no risk of leakage....

We've run aftermarket trans coolers with that same exact nipple set-up for years. Many rigs come back for servicing over 200K without issues and some of those units will push 250 psi plus at full stall with normal idle pressure of 55-70 psi and go up with throttle pressure from there. Quality clamps, quality hose, quality tech, tightening the clamps when the hose is dry and you'll be fine.

Guys get into trouble with that kind of stuff when they undo and redo and don't trim the ends of previous clamp locations on the hose. In those cases, replacing the hose is the best remedy. Also, the type of clamps Eric is using are better than worm gear clamps as the worm eats into the hose after time, and that's when leaks will start. Another note, trans cooler line is actually better than fuel line and will last longer than regular fuel line(hose)

I agree with Dave as that filter may be a little big to fit into the stock location

I did pretty much the same thing except I just cut the hose off the old filter and had napa crimp on the new fitting.

So has anyone ran into problems besides fitment using these aftermarket filters. It is about time to change mine and I might be interested in an alternative to the oem. Thanks for any info.

Cool, are you running the stock airbox with that filter? Location if so?

 

[mtnclmr]

No, I have the turbo, so no airbox.

the filter is only 45 bucks from polaris, it comes with the whole fuel line. i would rather buy it than cut all the hoses and not know it's completely sealed.

also, if you're going to replace it often. why are messing with all those bull**** clamps? if the polaris hose is rubber, just cut it and if possible slide the hose over the new filter and put the hose clamps on over the lip on the fuel filter. that's what we do with cars that have rusted on fuel filters.

I first did mine when the filters were $78. I also did it for the massive increase in filter surface area, and the filters are super cheap to buy.

So the original filter inlet is 5/16" and the outlet is 3/8"?

10-4 Elanore. I haven't said that since 1978, I kill myself.

fast, $45 filters for 07 & newer cfi ? Are you sure you are not pricing the 05/06 900 filter (it is blue fuel line and wont fit). Do share your purchasing power. EW

 

[05900]

Stock 05/06 900 filter has a black hose and looks identical to your pictures.
Replacements from High Performance Engineering #241-206 are $21.00 and have a blue hose. Are we sure they are not the same????? Like all manufactures Polaris doesn't "throw anything away".

The 05-06 hoses are shorter and will not work.

Eric...Great write up and pix.

Polaris filters are way to expensive.

There may be a smaller filter available from Napa/WIX.... I think for the Focus or Fusion??

Your clamps are good for the fairly low pressure (58psi) in the CFi system... not a problem there

Now... when do we ride??

MH, the Focus filters are a big filter. I was just thinking, do any motorcycles use these same type of filters? Size wise, they should be a better fit for the guys with stock airboxes.
