Spectra Sending units for use on EFI and LS Swaps for squarebody pickups

These sending units allow you to install a high pressure EFI fuel pump into your squarebody tanks. It is recommended you also upgrade to an 87+ tank

When completing a squarebody LS swap these senders allow you to install an EFI ready pump into your fuel tank. Choose FG05M for drivers side and FG05N for passenger side. 

These senders work well with our in tank Walbro 255 pump found HERE or our Aeromotive 340 Lph pump found HERE.
