Quantum's line of 340LPH direct drop-in fuel pump assemblies do away with the
unreliable and problematic venturi canister design found in 1995-2005 GM
trucks, vans, and SUV's. Previously, installing a high Walbro 255 or modern
340 pump into an OEM GM canister meant disabling the venturi system by cutting
"windows" into the sides of the bucket. Doing so results in canister drain
during hard acceleration or cornering, which leads to overheating of the fuel
pump. The bandaid solution is to keep the tank at 1/4-1/2 full or above.
Quantum's 340LPH assemblies resolve these deficiencies and allow the fuel pump
to be upgraded while retaining OEM functionality.
