For the fuel system, I decided to go with a Rick’s Restomod tank. I consulted with Carl at Vaporworx regarding the appropriate fuel module for my application. Because I’m expecting horsepower in the low 700s at the crank, and my LS7 is naturally aspirated, he recommended the ZL1 fuel module as an upgrade over the base LS3 fuel module. Carl is great - really knows his stuff.

I ordered the tank from Kim at Matt’s Classic Bowties. Big shout out to Kim - she is awesome... very knowledgeable, responsive and friendly. I ordered a bunch of stuff from her during their Black Friday sale and she was on top of everything and so easy to deal with. Tank arrived at AutoKraft a few weeks ago and looks great.

I’m also going to order from Carl his Vaporworx fuel module controller. The ZL1 fuel module puts out a lot of volume, but I won’t need that most of the time. Rather than running the pump constantly and restricting the output back to 60psi, the PWM unit will allow the pump to run at a fraction of its normal output, generating less heat and less wear on the pump. That should lead to long term reliability like an OEM unit.

The ZL1 fuel module uses PWM control from the factory; however, most people don’t use PWM in these types of applications. As a result, Ricks normally replaces the 88psi OEM regulator with the 60psi regulator that comes in the LS3 fuel module. Because I’m going to use the Vaporworx module, I had Rick’s leave in the 88psi fuel regulator. Using the higher regulator allows the PWM module to accurately sense the pressure of the fuel coming out of the module and cut back on the power to the pump as necessary to limit pressure to 60psi. Pretty cool stuff.
