Intermittently my fuel rail is wet with gas lately and leaking a small amount sometimes onto the ground. What are the possible sources?

Fuel Injector O-Ring?
Dying Injector Needing Full Replacement?
Deteriorated Fuel Injector Hosees --> Rail ?
Broken Rail?

 

The most likely sources are the rubber fuel hoses.

When the small injector o-ring leaks it floods the cylinder. If the large o-ring leaks you should distinctly see the fuel at that injector, so that just requires visual inspection.

I'm pretty sure a broken fuel rail would be unprecedented. This is not a part that experiences stress beyond the uniform fluid pressure it was designed for. Anyway, if this was the case, it would not be a minor leak, but an actual spray.

 

I'm thinking that too. Looking at the injectors, they aren't wet at all. I'll investigate more at next leak.

Mike, when I replace the new few hoses, is there some sort of conditioner or protectant that I can coat the hoses in to prevent them from drying out and cracking?

 

No, just be sure to use fuel-grade hoses, and tighten them well. You'll be good for another 15 years.

Old/cracked/dried up fuel rail hoses...Extremely common issue on these cars now..

Replace all, drive happy..

 

Dudes while I have access to those fuel rail hoses, is there anything else of moderate cost to replace while I have stuff dis-assembled - easy access.

Also for safety reasons, is there anything else hose wise or other that I can do during this same job, to prevent any of these potential fires from happening?

 

Check injector resistance.

Inspect injector harnesses for corrosion.

Inspect vacuum hoses for cracks.

The fuel rail sits on some rubber parts, if those are too hard or worn in some other way, consider replacing them.

 

make sure you use fuel injection hose not just fuel hose, it's about 4x the cost, but it is necessary.

 

Thanks...I noticed that too at the parts supplier. By the way, there is a variety of Inner Diameters of these hoses and from what I remember there was nowhere in the manual that specified the I.D. for every single hose.

Any guidance?

 

no clue on the specific diameters.
best option is to take off a section and take it with you to match it up.

 

I have the hose and length you will need. Replaced mine when I did my valve cover gaskets and the guy at the dealership didn't know how much I would need so I ended up getting like twice as much. $1.55 an inch!

Anyway, shoot me a PM if you're interested.
