Do I need additional fuel line, fittings, or a fuel regulator?

The tubing is included, but your setup determines what else you'll need. If you're running a fuel injection system, you'll want a regulator in line. Double-check your engine's fuel pressure spec before testing the pump.

Can I mount this tank in tight spaces?

The tank footprint isn't detailed here—measure your installation area against the physical tank before committing. Pump and line placement can be adjusted, but tank itself is rigid.

What fuel types does this pump handle?

Electric fuel pumps are compatible with standard gasoline. If you're running ethanol blends or specialty fuels, verify pump compatibility with your fuel type before installation.
