Product Details

The 31630 is specified for shallow cam filler necks and is listed for Ford trucks and vans that use a non-threaded filler neck design.

What It Helps Address

Installation Notes

Verify filler neck style before ordering. This cap is listed for shallow cam applications and for vehicles without a threaded filler neck in the Econoline fitments. Confirm the cap seats fully and turns to the proper stop after installation. Check the neck and sealing surface for damage or debris before installing the new cap.
