Great OEM product.

Bought this for a spare. Cap looks to be indestructible and at a great price.

Can't say it enough, Clay has built RiffRaff into a company that all others should strive to become. He offers the best products, USA made and by far the best customer service I've ever encountered from an online store.

This cap is just an example of what kind of business he does, he knows the motor craft caps are over priced ($60+++) and the cheap all in one caps from autozone or O'reallys are junk and leak so he has presented the best option on his site, as good as oem but a better deal then the big store brand.

I will ALWAYS look at RiffRaff first for my diesel needs. The only thing i haven't found on RiffRaff that I needed was a Tru-Cool 40,000lb gross weight transmission cooler.

Keep on keeping on Clay, you're doing a great job.

Works great doesn't leak like aftermarket caps. I am pushing 90 psi pressure

After using an aftermarket lid that looked nice with a nut on top for taking of and putting on, I bought this oem one and the fuel filter wrench from Amazon and never looked back. The first one I could smell diesel fuel all day, now everything is sealed up the way it should be. Not the first product I have ordered from this website and won't be the last, thank you guys for everything.

Great product. Avoid aftermarket caps. I put a two day temporary aftermarket cap in my 2002 F350 until this OEM cap came in the mail. In two days the after market (O'Reilly) cap/filter separated.

Fast shipping. OEM cap fit perfectly. Overall another great buy from Riffraff.

I was buying non-OEM lids and filters from AutoZone. After 2k miles on the last one the O-ring blew out on the highway and poured diesel fuel for miles before we realized what happened.

Got a brand new one from AutoZone and it would leak no matter how tight the lid was. Replaced with this and hand tightened (yes...with just my hand...no tools) and didn't leak at all. I did give it a 1/8 twist with a tool to tighten it up and works just fine. I'll go ahead and keep this lid and get filters from RiffRaff since they're cheaper than buying from AutoZone!

Had to use one of those stupid all-in-one filter/caps in a pinch and lost my old lid. Now I can get back to using Motorcraft filters with a quickness!

Perfect fit, excellent quality, factory o-ring. Installation and removal is a non-issue, especially with the OTC tool. Outstanding part!
