tank studs

[wesleyjohn]

i've got hold of a second tank for my R1150GS, but its missing a stud and a few are damaged, my idea is to cut them off grind the remains flat, and drill through and put astud through with an o-ring round it on the inside to seal it. anyone know of a glue or chem metal that i could use on the inside of the tank, just to hold the stud in place while i put the fuel pump on? and where i can get a fuel pump from, loads of tanks come up for sale but no pumps

.just to hold the stud in place while i put the fuel pump on?

Think things through - At a later date when you need to change the fuel filter or replace the pump, what happens to the studs when you undo the nuts .

Just a thought, and as I've got a stud broken on my 'old' tank, I'd be intrested in Steptoe's comments. Could you not drill and tap the stud locations for the appropriate sized cap-heads, and seal them with something like 'Plastic Padding', or maybe some of that 'Putty' stuff I've heard of for sealing fuel tank leaks?

at worst i'll have to use my mini disc cutter and split the nut.

I first removed the broken bolt and drilled and threaded hole where the bolt used to be
Cut the new bolt to required length and dremmeled a groove in the top for a flat head screwdriver.
Screwed the bolt in (from the inside out!!) till it was tight then re-fitted all the gubbins and a new gasket.

When it came to tightening up all the bolts I just took it very carefully, there made out of toffee or something, a screwdriver in the slot in the 'extra' bolt stopped it moving. I left the tank overnight over a drip tray pretty much full to check for obvious leaks

Been working just fine for a couple of months now

Hope this helps!

that sounds good, sidpick, didn't think there would be enough meat there to tap it but i'll give it go, just got to find a fuel pump now

you could get away with not putting a thread in, as you say its pretty thin metal, it just helped getting the bolt back through, right old bugger to do, very limited space in the tank.

I did toy with adding chemical metal to the mix to fix the bolt but the direct contact with fuel put me off adding anything other than metal.

Good luck!

What about those stud welding attachments for mig welders that fabricators use the studs are fitted into a gun and then they press a trigger, and the stud is spot welded to the steel.

Make sure the tanks empty and has been vented of fumes .
