Gumout

The name Gumout describes exactly what it fixes: fuel system cleaners and additives that clear out the carbon deposits and gummy residue that build up in fuel systems over time — the problem the brand was literally named for.

Gumout got its start in 1941 in western Pennsylvania, developed to solve a WWII-era problem: fuel shipped to Britain under Lend-Lease sat so long in transit that it gummed up carburetors before the engines ever ran. The original solvent cut through that residue, and the same idea — better chemistry in, better engine performance out — still drives Gumout's fuel system cleaners, injector cleaners, and fuel treatments today.

Fuel additives are a low-cost-per-unit, high-repeat-purchase category — exactly the kind of product shops and fleets order by the case, not the bottle. Bulk55 stocks Gumout in bulk so shops doing routine maintenance can reorder case counts directly instead of restocking one bottle at a time.

We carry Gumout in bulk, including the All-In-One Complete Fuel System Cleaner & Friction Modifier and Multi-System Tune-Up. Browse the full Gumout lineup here.
