Default fuel leak in 05 STi - HELP!!

I know there are a few threads about this, but I think mine is in a different location...unless I'm super special. I'm losing gas (like literally filling up every day) and I need to get this resolved ASAP.

I don't want to go and get raped by the dealership, so lemme know if I can do this myself or not. I have minimal experience on our engines.

zoom in a bit...

view from the top looking down. it isn't pooling a lot, but it's def there.

By chriskarel at 2011-12-16

I fear that the manifold has to come off to get to those lines. I'm not even sure exactly which is the culprit, but it's under there somewhere. Help friends! :/

$300 for the rails, try to get new manifold gaskets... if you want to go further do the tgv delete and get 4 manifold gaskets, if not just 2 gaskets...

I had the same problem and I just fixed it this past weekend. It was that the hose clamps under the turbo inlet were at least 3 turns loose. I then tightened them up and went away for a bit then the other side started to leak. The only way to fix it is to pull the the intake and replace all the rubber hose for the fuel line and double up the fuel line clamps. Plus while you are in there; there is no reason not to do the TGV delete and maybe put on a aftermarket turbo inlet. It is just an extremely poor design on Subarus part.

not gonna lie, I think pulling the intake manny off is way above my level. I would do more harm than good probably. So off to Subaru to pay $94/hr. for labor. :'(

This is just like the bugeye fuel line leaks that are getting fixed by Subaru. I would call SOA and tell them what you are seeing. I have to fix my leak soon. You must be losing a lot of gas if you have to fill up every day. This might be dangerous so get it looked at soon.

Today is 55 degrees and it's totally fine. But when it's under 40ish degrees I lose literally 1/8 tank in like 10 miles

Generally speaking, the hourly rate at the dealer is usually pretty close to the going rate for local mechanics - the price difference comes from the dealer charging the book rate (in terms of time) for a job, vs. what it actually took for time. If they are willing to do it, the service department at the dealership are probably the ones you want taking things apart, as they live and breathe subaru.

an eighth of a tank every 10 miles is a very bad leak - I'd try not to drive if at all possible (an engine fire is a tad more expensive to deal with than replacing fuel rails) - did you try to get a screwdriver on the hose clamps and tighten them up?

I had this same problem in my '05 STi. I called up Subaru, explained the problem, told them that there were some NHTSA cases opened about this same problem, and Subaru took care of fixing the problem. I would recommend calling SOA.
