Fuel filter, petcock.

I installed an in-line fuel filter but wonder if its causing my bike to starve for fuel. Doesn't do it consistantly but enough to be a PITA. Has anyone done this and if so what filter did you use.

Also, has anyone used a vacuum pump to test their petcock (insert jokes here), but if you did how much vacuum should it take to open the petcock diaphram?
 
fuel filter

Rammy, I have filters on all 3 of my Eliminators and have never had a problem in any of them. I bought 2 of them at advanced auto and another from a local bike dealer. Can't tell you the brand name though. They are all clear plastic and all directional filters, about 3/8 of an inch in diameter. Make sure the filter you have used is not on backwards if it is directional. (ie: one way only) good luck. Furchin
 
Also, has anyone used a vacuum pump to test their petcock (insert jokes here.............................ok,,,
.....i knew a guy who had 5 penises!,,his pants fit him like a Glove!!..... :lol:


yea,make sure filter is on Right way,they useually have a arrow on em ,,i run one&NO probs,,,i did have prob with tap,,put new Diaphram kit in&AOK now!!
could be the Diaphram!! 8)
 
I have it installed right but it must be too big for being a gravity fed line, insert another joke here. Starves for fuel with the filter, remove it and the bike runs like a raped ape. Let me know how what filter you have installed.
 
The general principal with in-line filters is the surface with the greatest exposed area faces the dirty fuel. That means a cone filter is fitted with the dirty fuel ariving at the pointy end and a cylindrical filter (paper or sintered bronze element) has the dirty fuel contacting the outside of the element.

With regards to you filter being too big, I doubt it. Again, generally speaking, the larger the filter the greater the surface area and hence less resistance to the fuel penetrating the element as there is more room to get through. I suspect you have a filter with an odd/faulty construction or the element has been contaminated with a fliud which has dried out and basically sealed the element, sometimes running fuel through it later will not necessarily dissolve the barrier. This can happen, even filters with clear cases can look fine because not all fluids leave coloured residue behind. Do you trust your source, sure they're not recycling?
 
Why don't you just try a new filter. It may be stupid of me to assume, but it is possible that the filter is clogged and you need a new one.
 
I'm going to replace the filter with a different type and hopefully that one will work. Any recommendations on filters.
 
i just use the clear plastic cone shaped ones with the brass mesh.........

theres lotsa varieties............go crazy!!....... :lol:
 
Yep, I'm with Doode. Mine's the same and these things don't cost and arm and a leg, mine cost a whole AUD4.00 back on 13Jun02 (its a Visu-Filter FF701C). I've never had a problem with it nor have my carbs been starving for fuel.

It's small enough so I could put down between the carb bodies (below the top diaphrams) so there's no kink in the lines caused by a straight section of hose (were the filter is) that won't bend were it needs to as it snakes it's way from the tank to carb. Also from the sides, at any angle, you couldn't tell its there.

That is like the filter i used and had installed in between the carbs. But after the heat got to it the upper barbed nipple bent over! Seen it on another zl too his was bent over as well. I switched to a all metal filter bought from autozone installed just above the pods and loops rearward a little bit. seems to work great.
 
OK thanks for the review. I'll keep that in mind, I must say that hasn't happened to mine although it did happen to one off my VF400F. Although it was bent it worked fine and 'cause it was cheap I went that way again. Just like all things glass plastic and rubber, when put under stress they suffer from cold flow so I made sure mine was installed so there was no strain on the hoses (in and out).

Metal filters are certainly stronger but I like to see what's being trapped by the filter, particularly to recognise rust scale as soon as it starts.
 
Fuel filter

I installed a fram filter from a ford. Filter is straight w/ a 1/4 inch inlet and a 1/4 inch outlet. The plastic one with the conical brass inside was 1/8 in and out and didn't keep up. Haven't had a problem since.
PS : It's nice to be back. Since the last time I was on an Eliminator site I increased the stable to include 2 more 900's and a Suzuki Madura 700 ( I know it's a Suzi, but it's rare as hen's teeth and the price was right )
 
...and last Tuesday I picked up a Dec '91 Yamaha XJ600S Seca II (Diversion in the states) with heated grips, gearsack rack, no damage to plastics or tank (dents or scratches) new discs and pads (front and rear) and 50% rubber F/R. All this with six months rego for $700.00 (that's our Aussie toy money and this from my Kawaasaki dealer who supplies most of my ZL1K bits).

This thing was listed at $900 so I offered $750.00 and he said make it a round $700.00 (needs a seat cover, rocker gasket and timing chain, ****, even I can fix that!).
 
oops

Sorry, my bad. Filter was for Ford, but not Fram. Purolator #F10024. Used 2 " hose to filter then gradual bend after filter to rack. Filter lays on top of #1 carb, but a bit of rubber double stick tape keeps it from causing any damage. Can't even see it the way the '87 tank hangs down. As for seeing the rust scale, the bike is almost 20 yrs old and unless it came from a place with 0% humidity it's gonna happen. Even the best fuel has a bit of "moisture" in it. Best thing is to keep the tank full as best you can and hope for the best. I knew an old farmer, who by the way was also an old bike, who used to drain his tank in the winter and slosh oil in it to coat the inside. He said that the first spring ride was a little smokey but he never lost a tank.
 
We don't have an off season here in Oz so another precaution I take is when the tank is near empty and I'm about to go fill 'er up I first put 500ml of metho in it to absorb any water in the bottom, give it a little sloshing (side to side) then put the premium unleaded in. Seams to work, but I only do this every other tank full.
 
GREAT NEWS GUYS!!!

Jeff,



We’d pleased to have ZL-OA join us on Club Row at AMA Vintage Motorcycle Days 2008.



There is no cost for a club space. I will put you on the 2008 list, but please shoot me an e-mail in April or May, 2008.



Best regards,



Will

I just sent another email to Mr. Stoner to see if he will send me dates for next years event. I will keep y'all posted!
 
I'd love to meet up with you guys and add another Eli to the crowd, but the cost of getting it there would be a bit prohibitive.


(Moab, that means I can't afford it)

:)
