QFS 340LPH In-Tank Fuel Pump Assembly, QFS-A81HV

The QFS-A81HV is a direct drop-in 340LPH high volume fuel pump assembly for
1999-2003 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups. Perfect for
forced induction applications requiring significantly more volume beyond what
the stock fuel pump can provide. Quantum's 340LPH direct drop-in fuel pump
assemblies eliminate the problematic venturi canister design found in all
1995-2005 GM trucks, vans, and SUV's. Previously, installing a high volume
255LPH or 340LPH fuel pump into an OEM GM canister meant cutting "windows"
into the sides of the bucket, thereby completely disabling the venturi
function and the ability of the canister to stay full during cornering or
acceleration, which inevitably leads to overheating of the fuel pump. The
bandaid solution was to keep the tank at 1/4-1/2 full or above at all times.
Quantum's 340LPH assembly resolves the inadequacies of the OEM canister
design, allowing the tank to be run down to empty just like stock.
