Gas tank seam, how close is the weld to the edge?, ...yes, I know this is a bad idea Options

Yes, I know this is a bad idea, let's get that out of the way.

Looking for a place to mount the clutch reservoir and the seam on the gas tank sure would make a good mounting spot. It appears that the seam weld is closer to the tank itself, but that position could vary depending on how good or bad of a day the operator was having.

Two options using the seam:

1. Drill the seam as far away from the tank as possible using the smallest reasonable fastener diameter that would reliably hold the reservoir in place and survive vibrations, bumps, etc. Literally a 5 minute job. Potential for a fuel leak down the road if I mess up.

2. Design a billet clamp to pinch the seam and bolt the reservoir to the clamp. Not difficult to design. Expensive to machine a one off part. Definitely would not leak.

It could be located somewhere else, but this location is easy to get to and provides for a good route for the reservoir to master cylinder line.

I do see the mounting tab for the evap canaster that could be used if I made a bracket for it. The line routing for that location wasn't as good.

Standing seam clamps for mounting solar panels on metal roofs is another way, but those were a bit too large.

I am open to suggestions!

Tygaboy made a nice mount for both brake and clutch reservoirs in the Ferrari thread.

Check it out for ideas.

He mounted near/on the vertical cowl support brace (center right of your last picture).

If I was going to try to mount that reservoir on the tank seam, I'd make clamps and NOT drill any holes in the tank if I could.
