Default Is it normal to accumulate substance by fuel pressure line?

I have just noticed that whenever I run my truck, there seems to be accumulating by the fuel pressure line by the pressure nipple on the muffler. It seems like dirt or burnt fuel which stains the line.

Is this normal?

It's probably exhaust resins (oil and soot), and dirt sticks to it because it's, well...sticky. Make sure the nipple is tight (tehehe) and use a zip tie or a very small and tight o-ring to hold the pressure line onto it.

Yes, I used to get alot of black goop around the fitting on my pipe. I started using zip ties and it helped alot, but it is a pain to have to cut them off and replace them every time I remove the pipe (for repairs). So I decided to use an o-ring, it doesn't work quite as well as a zip tie, but good enough, and it's reusable. I liked that idea so much that I use o-rings on all my fuel and pressure line fittings, as well as my air filter. The trick is just to find the right sized o-rings and my local hardware store has a great selection. They really make the truck easier to work on.
