DIESEL

Aluminum Fuel Anti-Drainback Valve

Three sizes available:

8mm / 5/16 in Fuel Line

10mm / 3/8 in

and 12mm / 1/2 inch for heavy duty applications

Many older diesels develop drain-back issues over time that result in difficult starting after sitting for awhile because tiny leaks in the fuel system allow the fuel to drain back to the tank while the vehicle is not in use. Finding and fixing the root cause can be very time consuming and expensive. In some cases, a more expedient solution is to install an aluminum diesel fuel anti drain back valve in the low pressure fuel system near the engine to prevent this problem. These valves are also called non-return valves and are essentially a calibrated one-way check valve. Heavy duty aluminum valve body stands up to harsh operating conditions, under-vehicle mounting locations, etc

These work great on older mechanical fuel systems such as Ford 6.9L / 7.3L IDI, GM 6.2L and 6.5L, Dodge 5.9L pre-2003, older VW diesel, as well as a myriad of tractor / agricultural and industrial / commercial applications.

Price is for one single aluminum diesel fuel anti drain back valve - both sizes shown
