1.) Is there such a thing as "connectors" to connect two fuel and pressure lines back to one? Like It tried to "draw" below

2.) Would their still be enough pressure to properly pressurize two tanks ?
3.) Would it harm the engine running it for twice as long without stopping it ?
1. What you're looking for is a T connector. There are numerous companies that sell that, but I'm not certain of the fuel line size so you'll have to look that up.

2. I think it would run fine, but since I haven't done it I can't say for sure.
3. Nope. It wouldn't be any different than filling the tank up over and over again. As long as it's tuned correctly you shouldn't have a problem.\
Personally I'd go with one larger tank. It shouldn't be all that hard to install and would be much less complicated.
