So as I'm chasing down this fuel leak, I was poking around under the hood just to make sure I didn't miss any obvious leaks or that nothing new happened. Well I got to looking more closely at the injector line bolts and it looks like some are threaded on more then others. Here's some pics 

 

 

theres not leaks or wetness anywhere and last I checked, they're pretty tight. Is this normal or should I pull them off and check for something? I don't really want to ignore this, but at the same time, I don't want create a new problem.

For our trucks I've used Loctite 545 on just about everything except standard bolts which I would use red or blue Loctite on. It's worked fine for me.

I've used pipe dope from ace hardware, but it did say fuel compatible. I even use it on JIC fitting not to help seal but keeps threads from corroding.

Because the plug in the head is already 3/4" I know this is a poor picture but you can see my two bushings 3/4" to 1/2" and the 1/2" to 1/8" then boost gauge. At least the line isn't in the way and won't get broke doing basic work like valve adjustments or injector work. Also the boost bolt is easy to break off being its a hollow bolt.

 

Did this to mine after seeing this. I like it much better down out of the way.
