Fuel leak under the hood

Fuel leak under the hood - 01/04/13 07:33 PM

Hi all! I could really use some advice from some of the experts. I will take a picture a little later today in case it's not clear.

I have a gasoline leak under the hood. I know exactly where it is coming from. Up on the top front area of the passenger side, right close to the fuel pressure regulator, there is a rubber hose that goes front to back. The rubber hose hooks onto a steel fuel line with one of those spring-loaded clamps.

Right where the rubber hose is clamped to the steel hose, fuel was dripping or sometimes spraying out. The rubber was no longer sealing tight to the steel hose. I moved the spring clamp back out of the way and put on 2 screw-on hose clamps and tightened them really tight, and it stopped the leak at first. However, sometimes when the engine is really cold, the rubber I guess shrinks, and then it leaks again, and once the engine warms up, the leak stops. I tried tightening the clamp tighter but it stripped the screw on the clamp. What I really need to do I think is replace the hose. It's getting cracked anyway.

So, is this a special kind of hose that can handle gasoline? Do you think Autozone stocks it? What I really want to do, if possible, is get all the parts I will need before doing the job, so I can do the job all at once and not need a ride to the store for parts. I might have to order some parts, after all.

It looks like to get to the hose, I will need to remove the top half of the intake manifold plenum thing. Sort of like what you would do to get to the fuel injectors. Maybe not as hard, I'm not sure yet.

So, what I'm wondering, if this is even possible, is can anyone tell me which gaskets and parts I will need if I take this top part of the manifold off?

So far I think I need a gasket for the throttle body, of which they make a metal re-usable gasket, so if I have the metal gasket I might not need to replace this one. Then I think there will be another gasket where the top half of the manifold connects to the bottom half of the manifold. I don't know if this is re-usable.

Anything else I'm forgetting? I'll take a pic later to help. I hope someone has already done this job before and can give some advice on what parts I'll need <img src="/forums/images/graemlins/notooth.gif" alt="" /> It's just hard for me to get a ride to the parts store and they don't stock Sportage parts much anyway so ordering everything in advance would be the best way <img src="/forums/images/graemlins/kewl.gif" alt="" />

Hi. Both my 2000 and 2001 Sportages had the same fuel leak. I did not remove any parts of the manifold. I removed the fuel pressure regulator and the hose at the same time. I used hose rated for fuel injection not regular fuel hose. It was probably more difficult to do it this way but I just didn't want to take more of the engine apart than was necessary. Hope this helps.

Cool, so I know that one end of that hose hooks to the fuel pressure regulator.

What does the other end connect to? Can you get to this other end without taking apart the intake manifold?

Sorry for such a late reply. I really don't remember if this hose is on the feed side or return side of the fuel rail without looking it back up. I used a long pair of needle nose pliers and alot of patience to remove the clamps. I then used a steak knife to cut/slice the hose longways for removal. Then measured and cut a new piece of hose and reinstalled everything. Hope this helps and good luck.
