At least I think it's fixed :-)

Had a slow weep at the shut off, so disassembled the sediment bulb. Used some TimeSaver to lap in the brass lever taper to the iron bowl.



Got a pretty nice fit, good and tight, but still able to turn. Used pressure on the lever handle as I spun the lever to lap the surfaces all around.



Then, cleaned out the bowl and lever real good to remove the lapping compound. Found a strong spring to use on the handle in the spring box, and fitting it tight and snug. New lead gasket on the screen, and all done.



This bulb going back on Nellie's new gas tank whenever that Brown Truck drives up.....

But just in case, the rebuild is going thru its QA testing in the Maxwell House coffee can, filled the bulb up to the top with gasoline and will rest there until I can't spot any seeps or wicking..... :-)

Don't ya just love this old machinery. You can fix it forever instead to having to throw it in the trash.

when I was still using the original style sediment/shut off on my 26 (it's a 20 year old re-pop), it also would weep. I talked to the tech guy at Langs (I think...it's been a couple years) & was told rubbing some soap on the mating parts was as good a fix as anything.

I lapped one once and used tooth paste

Toothpaste is good for a really fine finish since it has very fine particles in it, pumas I think, plus it makes brass minty fresh.

I use to keep a can of compound for emergencies, now the stuff is somewhat hard to find on the shelves, even in the auto parts store. I guess nobody tries to repair things anymore.

Dan: Your test set up is flawed. You need the weight of 8 gallons of gas on top of that shut off to really test the valve. Just my opinion.

Jack

You're too picky...you build engines,.. I can redo a sediment bulb :-)


Just joking, yea figured someone would notice, but a least it passed my 'quick test'.

Will install it in situ and see if the drip mat catches anything other than oil under Nellie !

Dan a one inch piece of pipe,10 inches long, with a bell reducer on it ,screwed on top with gas in it will give you the same head pressure,and complete your test set up.
