Review on Fill Sinister Diesel Powerstroke 1999 2003 by John Walter

I purchased this replacement cap without realizing it was way too expensive. Thanks to my knowledge gained in practice, I found that it also didn't fit properly, and leaked oil all over my engine. The construction seemed shoddy and without any thought to durability .The only upside was the quick shipping. I would not recommend this product to anyone looking for a reliable piece..
