Fuel tank mounts too small, suggestions?

Was hoping some of you experienced builders would have suggestion for a solution on my fuel tank mounting issue.

I have a Micargi Rover GX, and standard Grubee 49cc engine kit. The fuel tank mounting studs are too short for the accompanying mounting brackets, or the brackets are not deep enough to fit the studs, either way. This fuel tank mount setup was obviously designed for a bike with a much small OD top tube.

Is there a mounting kit that I can buy that will fix this? Or do I need to custom fabricate something to make this work?

I know, I thought the same thing about the studs, that must have been what was left of the threaded rod, and they didn't want to waste it. You have to love Chinese inconsistency!

I think I understand what you are describing and drawing. Piece of steel mounts to the front and back studs on each side. Nut on each side of the steel pieces onto the studs. Then the additional holes are used to mount U-Bolts up through the plate and around the bottom the top tube and secured against the steel pieces.

Is that about right?

I have a customer that is a genius with a welder. My other thought was to have him cut the studs and weld longer studs onto the tank. I don't know jack about welding, so not sure if it's doable or not, considering the thickness of the fuel tank.

Justin from Pirate Cylcles, gave me an easy answer. PVC conduit straps. Thanks for your help Mind Reader. Brad

It seems to be a better mount, and protects the frame if I line the underside of the fuel tank with bike tire inner tube.

Are there any potential negatives that I may not be thinking of here?

lol !!! duct tape, is there anything it can't do?
