Dripping Diesel fuel

I noticed a small ring under the coach. I appears to be fuel. I believe it may be coming from the hose in picture.

Do you have a question regarding your leak?

Don't recognize that particular fitting--appears to be near the air compressor/hydraulic pump drive assembly.....not likely an OEM fuel line is connected with hose clamps....more likely sources of a fuel leak on an older Alpine are: 1-injector pump; 2-injector line/injector; or 3-lift pump. Need to give us [me] a better idea of where this "leak" is located on the engine.
PS--we are currently staying in El Mirage right now.

Agree with other posters, we need to know where this hose is located.

Also, it's not clear if the "hose in the picture" means the large one with the repair or the smaller one above it. I cannot see evidence of a leak from either hose, but we need to know what you do see.

Finally, are you certain the fluid is diesel?

First step I would recommend is to clean the area well,removing all grime and fuel residue. Then you can make an accurate determination as to where the leak is coming from.

It looks like the oil return line from the turbo to the engine connection. If you turn the picture it’s a possibility. But I might be wrong.

Ok I found the leak. It is coming off the injector pump distributor. The bottom two Injector Snubber Valve seals need to be replaced. I hope that does it. The pipe connection to the snubber valve is tight and well as the snubber valve. Saw in another post here someone had the same issue. Again, this site has saved me BIG $$$$ and continues to be my main source of education. 6 new seals for snubber valves $55. If it works it beats the heck outer 1300 for new pump!!
