Corner Pickups & Fuel Transfer Lines
Getting the Most Out of Your Tank (Literally)
The fuel modules used in the 5th-generation Camaro, Aeromotive Super ZL1 (link to 68101) CTS-V2, Mustang GT/GT500, and many others use a transfer pump system to draw fuel from remote sections of their tanks.
For example, on the 5th-generation Camaro, the fuel tank humps over the driveline. The transfer pump draws fuel from the passenger side of the tank over to the drivers side where the fuel pump module is mounted.
VaporWorx has taken advantage of this by connecting corner pickups to the transfer pump system.
The corner pickup system allows fuel to be delivered to the module reservoir even when fuel levels in the main tank are very low.
During testing, it was found that with the corner pickup system, fuel delivery to the module was still working, even with less than one gallon of fuel in the main tank.
The corner pickups utilize a self-closing design.
The inlet side of the pickup is lined with a mesh screen.
When immersed in fuel, the screen allows fuel to flow through the inlet valve and into the fuel transfer tubes that attach to the fuel module transfer pump.
When fuel runs away from the corner pickup, the mesh is now clogged with fuel, just like spraying a screen door with water.
The clogged screen, with suction applied it from the transfer pump, pulls the inlet valve closed so that air is not drawn in.
Once fuel runs back to the corner pickup, a bleed hole will allow the pressure to equalize and the inlet valve will re-open.
See Photo 1 for a typical corner pickup.
The corner pickups are tied together using flexible corrugated tubes and a , T, or similar connector.
Though worm clamps can be used to attach the tubes to the corner pickups, Odiker-type clamps offer even clamping force and less chance of damage to the tubes.
Photo 2 shows how a typical corner pickup assembly will look like.
The corner pickups connect to the fuel module using a connection nipple on the base of the reservoir. The connection is usually a 3/8” quick connect that is included in the VaporWorx corner pickup kit.
