Gas smell outside the car, Y26SE
« on: 24 November 2017, 05:02:25 »
Hello, It's Friday!

...and gasoline smell in my garage. Omega 2001 V6 is really smelling now. Pipes under bonnet are dry, they go through inner wing (right side) down and then  somewhere. I cannot lift the car easily in garage. Any potential suggestions where to start. I think it is coming from back. Tank seemed to be made of plastic. I has driven with this car almost 200 000 km, about 240 000 totally behind. I never changed gas filter (just for info). Any help welcome as we have snow and floor is wet so it is difficult to see any leakage.

Filter is the obvious place to start, closely followed by the metal plate on top of the tank... the fuel pipes corrode here causing leakage.

Does it start and drive ok?

Thanks Doctor Gollum, I do my best.

Car starts and drives OK so far, perhaps minor leakage yet but in small garage and poor AC you can feel a small leakage, too. Same Garage have been here 9 years so this phenomenon is really new, that's sure.

You said top of the tank, can I see there from floor level or do I have to remove the tank? Can I see anything from the boot?

I am at work so did not even take the carpet away to see if there is something I could open in boot.

If you lift the carpet you'll find a plate in the boot floor you can remove for access to the top of the tank. :y

Root cause found. Gas filter badly corroded and wet, leaking. Reasonable place to change in garage. Just took the right rear wheel off. Never seen this kind of clips

How to remove them?
Do my gas leak to the floor if I remove the filter?
Do we have a guide here?

If not please help.

About a pint of petrol will come out.  The clips are made of 2 pieces, the bit that's on the fuel pipes, and the bit that sits on filter tubes. Press in lugs on the clips on filter tube, and pull fuel pipe off.

Refit - push clips onto new filter, then push fuel pipe on till it clips.

The clips can be brittle, so worth having replacements to hand.

That's useful in that you can see what clips look like.  IME, you can't use normal long nose pliers like he did, because the clip bits do not extend out far enough to grip, so you depress the clips through the square holes in the fuel line part of clip (there are special pliers for this, but can do something with small screwdrivers etc, though fiddly).

The strap holding filter in place is different on that Vectra as well, but the Omega one is simple to work out :y

On Omega estate, the fuel filter is slightly more awkward than saloon, just due to amount of room around it.

You are right. Video was "wrong". I bought those special pliers this morning. Job jobbed. Was not easy as it has been there about 17 years. It was difficult to get those clips pressed as they did not move in, perhaps dust, mud etc. Nice to have those pliers. I need them next time when 480 000 km is behind. Thanks for all again.

you probably want to change it a bit more often TBH.  When I ran my Omega on petrol, I tried to do it every 2-3 yrs, and it obviously came off easy then :y

Yeah, TBE is well overdue one.  But the highly strung thing has a huge list of other things that need doing...  ...mostly around trying to convince it to go in a straight line.
