Zoomer Gasoline Tank Universal Fitment (Partial Modification Required)

From the seller

I purchased this as a general-purpose fuel tank for a Honda Zoomer. 1. It seems slightly too large.

2. The fuel outlet at the bottom is oriented incorrectly and hits the plastic cover.

3. The fuel gauge type and connector are different. I tried to replace just the gauge with a genuine part, but changed my mind and gave up.

If anyone has the skills to modify it, please put it to good use.
