Questions & Answers

Is this part compatible with the Ram 3500 of 2020?

I have mine running on a 2020 2500, and you have it running on a 3500. For the exhaust fluid, I also have the blue on.

Do you have a 2014 Jeep Grand Cherokee Ecodiesel that this will work with?

It seems to be the case. My engine is the same as yours

Selected User Reviews For WHDZ Ram Diesel Billet Aluminum Magnetic Fuel Cap Def Cap Ram Gas Cap Diesel Cap

The design is great and it serves a very important purpose
5/5

My Dodge already has a rubber gasket around the fuel filler door but I chose this because ice, dirt, water, and dust could easily get into the filler neck and cause my fuel pump to put them into my All of these contaminants are not good for diesel! It just seems like a precaution I'd like to take. The Ram Diesel owners who have the new fuel filler neck might want to look into this. As for the magnetic bottom, it can be placed on the hinge and it will stay there while it is being fuelled. The o-rings also come with an extra pair Stack rings. A brilliant lime green anodized finish is almost visible at night.

An overview of alternatives to diesel fuel dust covers
5/5

With regards to the replacement aluminum billet cap, I was satisfied with its appearance, fit and operation. A high-quality material is used in its construction Material of good quality. It looks great and works Due to the fact the truck was purchased used, there was no dust cover, so I have no idea how the original looked or if it had one at all, but I like the way the green replacement looks.

The caps after the market have been great! caps are great for diesel and defense
4/5

Unfortunately, there are still two problems. This is what the diesel cap says Despite its size, the cap cannot be gripped because it is the same size as the fill spout. While I don't seem to have any trouble getting it off, my wife has a hard time doing it. This one picture shows you the one you need to see. *The def cap is as follows As the vents aren't very well positioned, your def will be dried out. I took a piece of wire, bent it up a bit, and rammed it inside the outside vent hole to solve the problem. Even so, a little bit of venting will happen. In the past, it would have done about 10% of what it would have done now. Texas is one of the driest parts of the country. In addition, the oring on the OEM def cap is made of viton. As well, the oring for this def cap is plain thin rubber! Also, they are made in China / I was very disappointed in them, too / ! (Br>Trump threatens to spank me if he discovers that.

I'm in love with It should be a standard feature
5/5

The cap that comes with the truck is much inferior to this. The gas cap on my new truck is like a . I cannot believe I spent that much money on my new truck. This is the 1st piece of plastic that goes into The first time I filled up, I actually threw it away because it felt like garbage, but it then became apparent that A magnet is incorporated into this cap so I can stick it to the fuel door while refueling. It fits snugly into the fuel port, came with a spare rubber O ring, and was coated in a rubber O ring, so it's non-rusting. As this is the first diesel truck I've owned, I need this to remind me not to fill it with gasoline.

Caps not needed on diesel engines, but they are great on DEF engines! Due to the cheap plastic cap sent by the factory, I was excited to purchase them
3/5

There is no problem with the DEF fill cap and it works perfectly. I'm very pleased with the way the Diesel fill cap fits and seals. But it's one of those things that is hard to grab because it's the same size as the neck and very It has never come back to me. I have never been able to grab it and fill the truck with it. For some reason, you have to pick up a screwdriver in order to raise it

It was apparent no one who built it ever tried it out. If you'd like me to handle it, let me know. It is best to make the knurled top around 3/4 inch to 1/4 inch thick so it can be held 2).

Make the DEF cap twist-off so you can take it off. I'd say it'll work fine either way. Also, the magnet is a pain to use. The filler door isn't strong enough to hold it down, so it falls to the Machining the cap with a larger / stronger magnet is recommended. A device that prevents the magnet from falling out would also be handy to me. I will have diesel fuel in the filler neck and tank over a period of time which will degrade the adhesive on the magnet. I was excited to receive these but disappointed when I saw how they performed. Buying from another place where the diesel cap has been modified to do the things I noted would be more attractive.

There is too much slack in the O ring of the diesel cap
3/5

It is good to have a defense cap. Using the same color for both would help differentiate them. A downside is it's not that easy to remove the Diesel cap from my 17 Ram because there is an O ring that makes it too tight. I cut my finger pretty bad one night when I was trying to refuel with the cap. To make it easier to remove the cap, it needs a smaller O ring. As for the protective fluid cap, it's not as bad as it could be. This is not really an issue for me.

There is barely enough magnetic force to make a difference
5/5

I have to be careful that it doesn't slip off painted fuel lid hinges because magnetic is not strong enough. Be careful if you cut open the inner shipping package not to cut through the extra o ring, as.

The great thing about them is that they are exactly what they claim to be
5/5

All Ram truckers have probably driven across the ground with plastic caps at least once with these. They are well made and much better than those. * However, I believe that there might be an engineer at Mopar who is able to realize that it would be a good idea to prevent access to the fuel tanks for other reasons than What happens if all of them live in the same There's no arguing with this.
