Want to save time filling up your newer GM diesel pickup? Transfer Flow has introduced a fast-filling fillneck kit that allows 2001-2004 GM trucks to use the larger truck stop diesel fill nozzles, which fill at a much faster rate than standard fuel pumps. Kits are available for stock OEM tanks as well as Transfer Flow's 45 and 56 gallon replacement tanks!
An assortment of fillneck kits have also been introduced for the 1999-2006 GMT 800 Silverado pickups. For those converting a pickup bed to a utility box, a conversion fillneck kit is available.
Transfer flow also manufactures straight and formed fillnecks for 2003-2006 GM 4500 and 5500 diesel cab chassis.
Please choose your vehicle's application below! Model Years are listed in the Product Box and the Fillneck Type is listed in the Description Box.
