Do you need to service the fuel rail supply on your 6.7L Powerstroke? The MAHLE Fuel Rail Supply Line Kit is designed to replace the O‑rings and sealing components that help maintain proper fuel pressure and prevent leaks at the fuel rail-supply line connection. Over time, exposure to high pressure, heat, and constant fuel flow can degrade factory seals, leading to fuel seepage, loss of rail pressure, or erratic injector performance. Replacing worn seals with this OE‑quality kit helps your fuel system run properly and supports consistent engine performance and reliability during service on fuel rail components.

Manufactured to meet or exceed original equipment standards, the MAHLE GS33712 kit includes precision‑engineered O‑rings and sealing materials built to withstand the extreme pressures and temperatures found in modern diesel common‑rail systems. These seals compress evenly and reliably at installation, creating a tight barrier that helps prevent leaks and supports stable fuel delivery from the supply line to the rail. Designed as a direct‑fit replacement, this fuel rail seal kit installs easily when servicing the rail, injectors, or related fuel components, helping maintain proper fuel system integrity for your 6.7L Powerstroke engine.

Best no-show socks ever!
Size: 6-10, Color: Black
If you're tired of wearing socks that slip off and show in your sneakers, then you need to try these amazing socks! They are designed to stay in place, even after being active all day. They are incredibly soft and comfortable, and they are truly no-show, so you won't see them at all. I've been using these socks for years and have never had any issues. In fact, I love them so much that I've bought multiple packs, and my family members have started using them too. Don't waste any more time with those annoying socks that slip off and show - give these a try and you won't be disappointed!

The best
Size: 9-11, Color: Black
Seriously the best non slip low cut socks you can find. They stay in place all day and I love the fabric. They are thin which I prefer. These are really the only socks I wear.

Great socks for the price!
Size: 6-10, Color: Black, Size: 6-10, Color: Black
I love these socks, they are perfect no shows but the material is thick enough for toes not too go thru. The grip is perfect and keeps the sock in place all day. I would definitely order true to size as the fit was perfect. I was surprised to find these socks at the price I did, especially when I got the socks in both black and white.

Best non-slip no show sock!
Size: 6-10, Color: Black
I love these socks! I wear them mostly with my slip on vans. The are thin so your feet can breathe (I hate thick socks). They have a grip on the heal so that they don't slip off of your feet, and it actually works! My only negative about these socks would be that if you have bigger than a size 8 foot, I would not purchase them because they do run a bit small. I wear a size 7 and they fit perfectly! They do look very tiny upon unpacking, but they stretch to the according size. I would also recommend letting them air dry after washing them and not putting them in the dryer. The first pair I purchased, I made the mistake of drying them and they shrank to an unbelievably small size. I've had my second set of socks for over 4 months now and have not had any problems since Ive been air drying them. I have not encountered any problems with them tearing as other have stated. Even though these are thin socks, they seem to be made quite well in my opinion.
