Many of the tanks come with rust...it's part of the package. Drop in a handfull of pea gravel and shake the heck out of it then flush it with hot water and blow dry it with compressed air before you install the fuel petcock. As for repairing the broken stud...it can be done but you need the services of a very good welder. New tanks are available but I'm afraid you're going to find the quality pretty much universal. As for twisting off the stud, this is a problem encountered by many first time builders and not just with the tank. Do not, do not, overtighten any nut or bolt on your engine, chain tensioner or rear sprocket. If it has a lock washer tighten it just enough to flatten the washer then just a slight twist more...very slight. Use Loctite on everything and don't listen to the advice that you need to retorque every time you ride. That's how bolts, screws, and studs get stripped or broken. Check thatsdax.com for a new tank but you might want to seek the advice of a local professional welder before you invest in a new fuel tank. Hope this helps.I am still building my bike and while test fitting the gas tank one of the bolts snapped about 1/4 inch from the tank. I can't see of any way to easily repair this so I guess I have to order a new one. Does anyone make a higher quality tank or are they all pretty much the same? the tank I have also came with some rust in it. I planned to put a liner in it but I don't want to spend money ($30+) on that unless I have a tank that will last. Please help.
Do you still have 1/4 inch of threads on the broken stud? If so it would be very easy to make a 5MM extension coupling. That would save you $30 bucks. It would be nice if they would make those studs 6MM, would save a lot of people a lot of problems.

Wolf,
Since these are gravity feed systems it will definitly have to be vented with a vented cap or whatever. Don't think just a expansion valve or check would work.
ILL POST SOME PICS AS I JUST GOT A FEW TANKS OFF LINE TODAY IN THE MAIL (T&A). I POSTED THE TANK WRONG, ITS ONLY 24 OZ. BUT SHOULD BE FINE PROVIDING SUFFICENT VENTING TO PREVENT VACUUM ON THE TANK AND MAKING SURE OF ANGLE OF TANK AN HIGHTH/ GAS HEAD PREASSURE/VOLUUM FOR GOOD FLOW.I PUT AN INLINE FILTER AND VENT OFF THE TOP WITH A COILED UP FUEL LINE TO PREVENT BACK FLOW WHEN FILLED.ILL FILL IT WITH A 1'' STAINLESSPIPE/90 DEG I FABED ALONG WITH A CAP I FABBED AS WELL, I DRILLED A 1'' HOLE IN SOME SPARE PLEXYGLASS PIECES AND WILL DRILL THROUGH THE DUMMY TANK WITH 4 HOLES AROUND THE 1'' HOLE.... ILL DO 4 CLEAN RIVITTS HOLDING THE TWO TANKS TOGETHER... ILL POST PICS AS THEY TELL THE BUILD BETTER THAN I. I HAD TO FLIP THE TANK UPSIDEDOWN FOR GRAVITY FLOW TO WORK PROPERLY AS YOULL SEE IN THE LAST PICS.SPENDING TIME WITH MY BOYS UNTIL 8;00 45 MIN. THEN ILL PUT THEM TO BED AND CONTINUE THE TANK...PLEASE EXCUSE THE SPELLING...( ALWAYS)
ILL PUT UP MORE PICS IN A MIN. THE FITH PIC IS THE SECOND VENT(ON EITHER SIDE) OF FILL SPOUT..
Hres 5 More Pics( Max??) I Have One More For Now .. I Think You Will Get The Idea..
OK, WIFES HOME EARLY!!! WOOHOO... GOING DOWN TO THE GARMANRAGE TO FINISH..HERES WHERE I LEFT OFF. ILL HAVE TI TRIM THE PIPE AS I LEFT IT LONG .. ILL ALSO DRILL THE TANK ON THE PRESS @ WORK TOMARROW ALONG WITHFULLY MOUNTING IT. IM THINKING THAT I MAY HAVE TO RUN THE INLET LINE FROM THE PLASTIC NIPPLE UNDER THE TANK LOWER FUEL LEVEL.. WE WILL SEE.ILL SIMULATE TOMARROW.
I ASUME YOUR REFERING TO THE SET UP IT HAS NOW -I UTILIZED CRAP PARTS, PLEXY GLASS, ALUMINUM ANGLE , STAINLESS PIPE, UNION ECT..AND CUT AND WELDED TO FAB EVEN THE FUEL CAP. PLASTIC EPOXY-6.00$ , R/C PLANE TANK-10.00$ SO IT COSTED ME 16.00$.. NOW , TO DO THE MOLDED INLINER TANK IT WOULD COST MAYBE 25-30$ IN PARTS/MATERIAL, BUT SHAPING THE TOOL AND CASTING THE MOLDS IS THE TIME CONSUMING PART. IM MOST LIKELY GOING TO GO THIS ROUTE WHEN I GET TIME OR IF THIS TANK IS NOT GOOD ENEPH. I FIGURE THAT THE MOLDED TANK SHOULD HOLD OVER A 1/2 GAL.( MORE THAN THE STOCK....)THE ONLY DRAW BACK TO THE INNER TANK SET UP IS BEING UNABLE TO VISUALLY SEE YOUR FUEL QUANITY... I DIDNT WORRY ABOUT THHIS TOO MUCH AS I HAVE A SPEEDO AND WILL DO SOME T/A TO FIGURE OUT EXACT MILAGE@ FIRST.
