Fuel cut off soleniod valve...

admin

Last year I saw fuel cut off solenoid valves sold on ebay for use on welding machines and tractors with gravity fuel feed.  It automatically shut off the fuel to the carb when the engine was not running.  This eliminated haveing to shut it off manually when not in use due to so many of the carbs not having good float valves which usually meant the gas filled the carb and ran out the air intake.I have a customer who I rebuilt his welder for that has two machines he would like me to install these solenoids on.  Now I can't find them.  I'm sure sombody still makes and sells them.  If anybody out there knows of a source please let me know.  I need to find them soon.Later...Dave B.E-MAIL:  [email protected] PAGES:  www.wfmservice.comwww.rides4rides.comwww.pvpmedia.com/53f100.htmDad always said, "If it ain't broke, don't fix it."I say, We can make it better.

Reply:Howdy DGB,You probably need to look for a motor shifted valve, rather than a solenoid valve. Most solenoid valves are for higher pressure systems than gravity flow would provide. Lots of gasoline trucks and motor-homes use 12v fuel tank selector valves. I suppose you could block one flow path and use a selector valve as a shut-off.You'll have to "get past the guy at the counter" and look for yourself in the fuel systems catalog. I'm thinking Master or Pollok brand.  I know that Master brand has lots of funky fuel system accessories.Good LuckAnother though - It'd be redundant, but I think if you install a fuel pump, gravity flow alone won't have enough pressure to unseat the pump's pressure check valve.Last edited by denrep; 09-04-2008 at 08:34 PM.Reason: New idea!
Reply:I just looked in the hardcopy catalog of MSC Industrial Supply Co.  (mscdirect.com  ) and see a large selection of Solenoids. You pick the coil from one area and match it to the body you need. I didn't check to see what seat material is available, but imagine Buna-N is what you want.
Reply:Interesting, not many to be found. I suppose the demand must be pretty low. Looks like a marine application tho. Confined space thing maybe. These seem to be all orificed through put but it's really hard to tell from just the glossy brochure info. One of them might be straight through. Small orificed through put might not be great for gravity feeds if it was located in the wrong place. Operating pressures anywhere from 30 lbs to 312 lbs. Fairly high draw to keep them open. http://www.dan-marc.com/rv-parts-12-...ff-valves.html
Reply:Wow Sandy,Good find! Purpose built, and cheap too. That's gotta be the answer. Unless DGB goes with the "turn off fuel to collect pay" sign.That distributor represents a real menagerie of products in his line doesn't he?Must be whenever he buys something he becomes a rep! But will it flow?Here's a link to the manufacturers specs including flow chart:http://www.afcvalves.com/mod123.htmlLast edited by denrep; 09-05-2008 at 01:28 AM.
