LS Fuel tank options

[ADiCarlo]

Just a clarification. All vaporworx tank options are single line to the fuel rail. No external pressure regulator or return line needed.

Hi Carl,

But running an external is an option? I ask because I've been thinking about going turbo and that would require a regulator that could reference the boost pressure correct?

Hi Carl,

We can do boost referenced as well in single or twin fuel module arrangements. Twin ZL1 fuel module setups are becoming more common due to the ease of being able to make big horsepower. At 65psi twin ZL1 setups can provide 736 lb/hr of fuel. At 0.6BSFC that's enough fuel for 1225hp.

Running an external mechanical regulator/return can be done but there are some drawbacks. First, the return must be set up to dump the fuel back into the module reservoir. Hence, an internal flexihose must be used to route the fuel accordingly. Second, the total costs of an externally adjustable regulator, fittings, hoses, etc. on a full fuel-rail type return system, etc. the vaporworx pwm controller becomes an attractive option. Less heating of the fuel, less noise, longer pump life, fewer hoses, and more available real estate under the hood make it a viable option.

The ZL1 fuel module is also E85 rated from GM.
