FUEL CHECK VALVE 1/4 INCH HOSE

Product Description

One Way Fuel Check Valve 1/4 Inch Hose

One way fuel check valve, used to prevent fuel drain back. Fits 1/4″ hose, can be used with 3/16 hose however, it is a tight fit.

The check valves on the fuel filter housings for 6.9 L IDI and 7.3 L IDI are obsolete. We use this check valve, installed in the return line off the filter housing, to help prevent fuel drain back.

Note: the 1983 – 1990 used a 3/16″ return line, with offset tees on the injector returns. You can use this check valve on the 3/16″ return line, but it is a very tight fit. We have been unable to locate any 3/16″ check valves. Order at your discretion, knowing that the hose will fit, but it is very tight.
