Bosch Stock 503 Fuel Injector 03-04 Dodge 5.9L CumminsWhite smoke? Hard Start? Missing or ticking noises? No start at all? It could be that you have 1 or more bad injectors. Injector failure on the 03+ Common Rail Dodge Cummins trucks is usually caused by either bad fuel or the use of power adders that increase rail pressure. Bad fuel can cause injector failure immediately, pressure boxes will cause failure over time. The best insurance against bad fuel contamination is to run a 2 or 3 micron aftermarket

White smoke? Hard Start? Missing or ticking noises? No start at all? It could be that you have 1 or more bad injectors. Injector failure on the 03+ Common Rail Dodge Cummins trucks is usually caused by either bad fuel or the use of power adders that increase rail pressure. Bad fuel can cause injector failure immediately, pressure boxes will cause failure over time. The best insurance against bad fuel contamination is to run a 2 or 3 micron aftermarket fuel filter in combination with a water separator. We offer inexpensive options from Glacier Diesel Power and The Right Connection. For those of you that want to add filtration AND increase the fuel supply, we offer pumps from FASS, AirDog (PureFlow),BD, and others.

BOSCH ADVANTAGE: The advantage to being rebuilt by Bosch is they have the ability to completely "gut" these injectors from input to output to ensure they are as close to new as possible. The only "Remanufactured" part of these injectors is the housing. All internals are brand new and put together the right way by Bosch. There's no reason to pay enormous costs at the dealer.

Priced per injector. If you need a set, you will need to purchase 6.

Nice bed
Color: Blue, Size: Large (Pack of 1)
Good quality dog bed. My pittie loves to burrow himself under blankets so I figured we would give this a try. He hasn’t figured it out yet but it’s his new favorite spot to take a nap when he’s not on our lap. Love the color and seems to be nicely made. I do wish it came in a bigger size but it’s still big enough for him.

Nice quality bed

Nice quality. My dog loves laying on this bed but hasn’t yet figured out getting inside. I cover him after he lays and he seems to enjoy it

Cozy Bed, Just Needs Fluffing
Color: Blue, Size: Large (Pack of 1)
Our dog took to this bed pretty quickly and seems to like curling up under the cave cover. It’s soft, roomy, and gives that little tucked-in feeling a lot of pets seem to love. The cover doesn’t always stay perfectly shaped, so I have to fluff it back up now and then. Other than that, it looks nice in the corner and seems comfortable enough for daily naps. Solid bed overall, especially for the price.

NOT WATERPROOF OR MACHINE WASHABLE
Color: Blue, Size: Large (Pack of 1)
Until today, I would have given this bed 5 stars. When I was looking for a new pet bed, I searched for “waterproof” and “machine washable”. My bad for not verifying those attributes before purchasing as I have learned Amazon search results are not reliable. Today one of my dogs peed on the floor and dragged his bed over it. When I discovered it, I wasn’t concerned because it is waterproof and machine washable. Uh, no it is not. The cushion was wet and was too big to adequately fit in my washer and I could tell the fabric wouldn’t hold up so I hand washed in the tub. But by this evening it was still pretty wet so I tossed it in the dryer on low - by itself - to get the damp out. Well, when I took it out, the cushion had ripped open. Meanwhile, I put the cover in the washing machine. It washed okay, but the plastic part that helps the the opening stay open came out and broke. I cannot find a hole to attempt to put it back in. I am really irritated that it isn’t better made.
