Pump, Fuel, Dual 340, 99-04 Chevy Truck - Part No. 18313

This system is designed to work in plastic
fuel tanks only; some of the 1999 models still used a steel tank. The
1999-2004 models used a smaller factory fuel sending unit than the
later 2005-2017 models. The smaller size limits the pump
configurations that this tank will accommodate. These tanks will
accommodate; single 340, dual 340, and single 450 pump
configurations. Any other combination of pumps will physically not fit
through the factory sending unit hole. The Silverado and Sierra tanks
have a tank depth of approximately 14.00”, while the other models are
more shallow and have depths around 8.25”. The new system will
accommodate both of these tank depths. The 2500 truck models can
have a deeper tank up to 17.00”; the system will also accommodate
these depths as well.
