Fuel Filter/ Tank Coating

[dreamaker]

I have been having small intermittent issues with my Valk, I get a slight flutter when I cruse.  Seems fine when I first start, but I can here it more when it warms up but idle bounces slightly. You name it I changed it. Synced three times, seem to run better each time but back to flutter. Now understand most people wouldn't notice it but I do, Valks have a hum when they run good and mind is slightly off. I decided to clean my jets and they are pretty new, so rather then letting them soak for a few days I bought new ones so I could change them out right away. So I took the bike for a test run and it seemed to run better, I then cruised in third gear and brought the RPM to 3500 for a short distance to get the blood flowing. It then started to flutter then I started to get a pop from the right pipe. I got home an started to pull plug wires while it was running and when I pulled #3 the pop stopped. So I checked the spark and it was fine but 3 wasn't firing, so at that point I knew it was dirt. Pulled #3 bowl, looked clean, I then pulled the jets, blew them out and seemed to run fine. My question is, what has been used successfully as a in-line filter. Just in case there is crap in the tank, What is suggested for coating the inside the tanks if there is rust inside. I looked inside but couldn't see any rust but I could have missed it. I'm going to see if anybody I know has a bore scope and recheck it.

Believe it or not all gas stations are not created equal.  You will get a lot of crude filling up
over a years time.  I rinse my tank out ever time I take it off.  At least once a year.  My
tank is clean.  Below is a picture of what I got out of it the last time I rinsed it out.
A piece of wood, lots of rubber like stuff, some rust, (not rust from my tank) but from the
gas pump.  Check your screen to make sure there is no hole in it.  Hard to see sometimes.

Lee, What did you use to wash the tank out, just gas or something else.

I use a gallon milk jug and about 3 qts of gas.  Take the petcock off, you can hold the jug up on the
nipple and the big end of the tank with one hand, the little tank end with the other hand.  Close the
lid slosh the gas around and drain into the jug.  Let settle for a min then pore the same gas in the
tank again.  Just don't pore the crude back into the tank.  Repeat until you think all the crude is
out.  (And you will get some crude.)  Empty the jug because the gas will eat a hole in it if you
leave it over nite.  NO SMOKING during the process.
DO IT OUTSIDE over an old rug or something just in case you mite drop the tank.
OF course make sure the SCREEN is out of the tank.
The crude you will get does not mean your tank is rusty or anything.
 You get a little at the service station every time you fill up.
Pour your findings through an old tee shirt and post a pic of what you get.

If you can't see rust with a flashlight and mirror then it probably is junk in the gas. My tank was rusty. Check out Caswell Epoxy http://www.caswellplating.com/aids/epoxygas.htm
I also installed a Golan fuel filter. Russell and Pingle also make filters, though I don't have experience with them. Some have had problems with insufficient fuel flow. I hear a Goldwing filter will work well. JP Cycles has a bunch lhttp://www.jpcycles.com/Search/Search?Ne=0&N=0&Ntk=All&results=10&Ntt=fuel filter&No=10isted
Good luck

    I have been restoring British cars (for a living) for the past 20yrs, so I have cleaned a lot of nasty gas tanks. Here is what I find that works the best. Too get old dried gas out of your tank or carbs (dissasembled) use lacquer thinner first and then if you have a lot of rust use Muriatic acid (BE CAREFUL) and NEVER, NEVER put a sealer in you tank. I don't care what the people selling it say, it will sooner or later peel off and then you will have a real mess.

I look the best I could with a light and a mirror and didn't see ant rust. So I guess it is the trash I am pouring in to the tank at the gas station.

To answer your question about a filter... I'd have to dig out my box which I'm nowhere near to be sure, but I believe the NAPA number is 3027.  It's a small in-line filter with a metal housing and 5/16" nipples on each end.  It was made for some of the Ford V8 products in the 70's and flows plenty of fuel.

Now my creative juices is starting to flow. Does anyone know where one can get. I guess you would call it micro screen.

I use the 19-1252 5/16 IN LINE FUEL FILTER Round type, brass screen type element shown in the link. They are cheap and work well

Just installed a quick disconnect and the inline NAPA filter refered to erlier. The NAPA nunber is 3027 and works great.

Finally pulled the tank and pulled the petcock. Also pulled the filter screen from the tank and I noticed that the part of the screen closest to the tank, which would be the reserve part, was twisted about 45 deg. There was some crude in the tank but not as much as I expected. But if it got by I guess it could clog the jet. I was wondering if anyone flush there tank with soap and water. I was thinking maybe flush with water, drain, let dry then slosh with Seafoam and add gas with Seafoam. Going to order a new screen and try to get it shipped yesterday.

Mine was twisted too, but the filter was ok. Have to hold the petcock assembly steady real good so it doesn't twist at all when tightening up the nut. I don't see a problem with soap and water as long as it's rinsed out well with SF and gas after. I'd be a bit concerned with not getting all the water out?

I ended up washing it out with gas three times, and I straitened the filter and basically did like you said. I also put an in-line hi-flo gas filter but had a problem with that. I used the squeeze clamps that came with it and I guess when I was putting the hose on the tank I pulled it out of the filter. I took it out for a test run and got about 3/4 mi. from the house and it died. So i was trying to see the problem and seen the hose detached from the filter. So I had a choice, push 800+ bike down the road , instead I messed around for about 15min. and pushed the hose on. Trying to started but know fire, so I pulled the #6 vac. hose and started sucking my brains out to get the gas to fill the carbs. because the battery was going down. Finally got it started a hobbled home. Sure the neighbors got an eye full. So the point is if you use an in-line filter use screw clamps. Seem to run better, maybe later when the new tank filter comes in I will clean the jets and re-sync the carbs.

Thank You all again for all your help !!

......... the petcock diaphragm should hold vacuum so if you just suck on the tube and then stick your tongue over the end it should hold the vacuum and keep the petcock open while you allow the carb bowls to fill..... but don't let me interfere with whatever you consider foreplay with your phat lady, whatever works.......glad you made it home....
