Perfect retrofit fuel module. fit my tank perfectly and the 255 LPH flow handles my mods with ease. Rock solid Holley quality as expected.

My fuel pressure was inconsistent on my LS swap project under hard acceleration. The Holley in-tank retrofit module at 255 lph fixed the problem completely. Fuel pressure is rock solid now at all RPMs and loads. The installation into my existing tank was surprisingly clean. No custom fabrication needed. Great quality sending unit included. My builder said he’d recommend this approach to anyone doing a performance fuel system upgrade. Problem solved, car runs perfectly now.

Upgraded my fuel system with this Holley 255 LPH retrofit module to support the extra power my build is making, and it dropped right into my factory tank. No cutting or fabrication needed, which I wasn’t expecting from an in-tank upgrade. Fuel pressure stays rock steady even under hard acceleration on track days. Noise level is impressively quiet compared to my old external pump setup. Everything included in the kit was exactly what I needed, no extra trips to the parts store. Great retrofit module for anyone stepping up their fuel demands.

Went with the Gibson Black Elite cat-back for my ’20 Sierra 5.3 and the sound upgrade alone justified the price. Deep and rich under throttle but stays quiet and refined on the highway, no annoying drone at cruising speed. Black ceramic tips are a nice change from the usual chrome and have held up well so far. Install was a clean bolt-on job, took about ninety minutes with basic hand tools. My truck gets noticed in parking lots more than trucks with big lifts now. Excellent exhaust for the money.
