Fuel cell with bypass to cut off main tank

[Trickplay24]

Wondering what the best way to add a fuel cell that can be turned on with a switch. Basically the best way to drive daily on regular tank then flip the switch to use the fuel cell supply ? I am planning on using a second supply pump on the switch with a manual cut off on the main tank and connecting the fuel cell line as close as possible to the motor with a 2 to 1 link for the fuel lines. I know there will be some regular gas in the lines which is why I'm running on a separate pump and hooking in as close to the motor as possible. also dont think its anything a quick drive won't take of. Any one else done this set up or have any ideas ? Thanks.

The fuel return will have to be doubled, one for pump gas main tank, then another for the fuel cell and race gas.

If not, then the returning fuel will be dumped in the gas tank and not the fuel cell.

Basically 2 fuel systems sharing a common fuel rail

^ Perfectly said. I was thinking of how to word it, but after reading that post, its exactly what I had in mind. Good info Bogus!

I guess I wasn't perfectly clear as I didn't even mention return line ! Have any of you done this ? Just wondering if there's any other setups ? I like it because you can drive around on regular flip the switch and go play with your friends on a Friday night. Also thought about duel injector fuel rail running a completely independent fuel cell to alleviate the regular fuel. Anyone tried that ? I have never used a duel injector fuel rail so not sure if that is possible

Have you given any thought to installing a methanol injection system?

Yes I am currently running a meth injection kit. With mythe mods and timing issues/detonation I will need race fuel. Big turbo using nitrous to help spool plus meth. Built bottom end forged and ceramic coated, 1mm over valve springs 272 cams all supporting mods, aem stand alone, axels , built transmission and diff. Basically a money pit . I use it as my daily driver with 2 programs one for daily one for playing and 1/4 mile runs. Just interested if anyone has done a different set up that is easier. This was my first 4g63 build and I wanted to do it right and have learned build it right the first time as it saves time and money. I will load some pics as soon as I get the body finished and painted. Now on to the next 2jz into a 240sx( "that won't be a headache !").

Why deal with seperate tanks at all? If going to the tank, drain as much of the tank as possible, and add race gas. When on the street, drain the race gas into a container and add regular fuel.

I enable fuel pump via dsmlink and remove the feed line and drain my tank that way (2g) for pump gas to daily it.
