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.
Installed this QFS fuel pump in my Hyundai, and it’s been working perfectly. Really like how well it fits and the solid build quality. It’s nice to have a reliable pump that works across multiple brands. Would buy again for other vehicles!

Good replacement fuel pump for my Chrysler
I used this QFS fuel pump to replace the old one in my Chrysler, and it fits great. Performance has been solid so far, and it was easy to install. Just make sure to double-check the wiring before you put everything back together!

This pump failed after a week
I really wanted to like this QFS replacement for my BMW, but it stopped working after just a week of use. I followed the installation directions carefully, but something must have gone wrong. Very disappointed!

Decent pump, but instructions could be clearer
The QFS fuel pump works well enough for my Ford, but the installation instructions were a bit vague. I had to watch a few videos online to figure it out. Once I got it in, no complaints on performance!
