Title: Fuel Filter Replacement
Post by: Michael on December 05, 2009, 02:23:57 PM
Is my fuel filter supposed to look this crappy? Or is the "old and yellow" look normal?

And do I need to buy OEM, or can I just get a matching filter from Napa for cheap?

Thanks.

:)

Mike,

I assume your bike is a carb model, and then the answer is yes, go ahead and buy the Napa filter...Or any other brand you like.

Carburetor = yes

Thanks.

And brand recommendations? Does anyone have a favorite or a brand to stay away from?

usually, since there's no high pressure in the fuel system, any brand will do, just make sure that the inlet/outlet are in the same positon, if not, buy a longer fuel line...You shouldn't spend more than $12.00 on everything...

That's for FI bikes I think. It would work, but the lines would be pointed in the wrong directions.

The local autozone has an exact duplicate up on the wall.

Take yours and they should be able to match it.

+1 on this.. They used to have their private label "Deutsch" for a while and then had a closeout, I picked up 2 dozen of those for 99 cents each...   

sorry, just had to share.. but they have them.. they are nothing special, just a paper gauze filter.  the discoloration is normal.

* UPDATE *

$5 at Auto Zone -- new fuel filter!

I also got new hoses (both for the fuel line and the drain lines -- just generic rubber hoses that they cut to length down at Auto Zone) and a pack of hose clamps to replace the break-away kind.

Good luck getting the new hose to make that U bend w/o pinching. I couldn't get a satisfactory bend.  >:(

It was no problem, I just had the guy cut a little bit of extra hose -- just a few inches. And so instead of a sharp bend, I'm able to make a wider curve with no pinch in the line.

How did it all go back together?  I notice from the pic that the inlet is on the opposite sides between the old and new filter.  Oh, and FWIW, I noticed on my '99 that you really don't want to clamp that baby tightly to the tank. It needs to rotate a bit as you raise and lower the tank or it will put a crimp in the line.

I think the "opposite side" bit might be helping with the radius of new to OEM hose as well.  Good on you for replacing it.  I didn't and, combined with the "crimping" I noticed later, my OEM hose split and drained almost an entire tank of gas onto my garage floor one night.   :-\

Everything went back together really well.  :)

It feels like I'm accelerating better, too.

You're right about the filter needing to be able to turn, but it's not really an issue because the filter is smaller than the clamp. So you can still tighten the clamp screw all the way and the filter will still have room to wiggle a little.

You underestimate my ability to mess up even the most straightforward process.   [laugh]

For those interested in replacing the clamps with exact OEM clamps...

There is a site www.liquidiceusa.com (//http://) they sell the Oetiker clamps and the crimping tool.
If you look at your existing clamp at the crimped area on one side, you will see the size of the clamp. On my Street Fighter it was the 15.7mm. I ended up using a 14.3mm since I had two occasions where my fuel line came off inside the tank... leaving me stranded and pissed.

Using the crimper is a BREEZE! No slipping, one shot, ba dah bing!

A standard screw type band clamp, IMO, does not crimp evenly and is not good for FI use.

The crimp tool is about $20, and bags of 25 clamps are $7.50.
