    I have a petrol leak coming from the top front drivers side of the petrol tank it can be spotted from behind the drivers side wheel.

    its not dripping just making the front of the tank look darker than the rest.

    i highly doubt that the tank itself is leaking but more likley a hose some where.

    are there any common pipes that leak around that area and whats involved in fixing this myself

    cheers

    Check if your fuel sender gasket is wet or damp around the edges, if so then you have found your culprit. If not then clean the stain off the tank with a bit of turps or metho and watch it carefully over a few days/weeks to see if you can pinpoint it.

    Yeah, the best idea is probably to clean it all up really nicely, then see if you can spot where it's coming from over the next week or so.

    Had the same problem, turned out to be the 2 surge/overflow hoses which run from the filler neck down to the tank were broken, easy enough job to replace, but you need to drop the tank to get at them.

    I also had to replace those 2 hoses. Mine use to leak a fair bit when I filled the tank.

    if it is the surge hoses, you do not need to drop the tank, jack up the car rear right side remopve the wheel and inside the wheel arch you will se an inspection plate remove it and you will see all of the hoses etc, you can change theese hoses from hear.

    Sorry to bring this thread up again.
    Mine leaked from this area several weeks ago and brother and I checked all hoses and they just crumpled in your hand...replaced most of them but the 2 hoses that go into the tank can't be unplugged and this is where the tank has to be dropped to be able to replace these 2 hoses.
    Any idea of costs for this?

    Apparently on the VN it was a common problem for the fuel tank to corrode around where the pump is.
    I know of 2 that have had to be repaired or replaced because of this.

    Sorry for the delay in this, got a mechanic to do this for $99 plus i have a towbar, so i thought it wasn't too bad....mine was a july 93 vp so very near a vr, but not quite enough.
    Good car though imo, beats my old 4cylinder telstar that crapped itself every year!
    Had this car since late 2003 and not much has gone wrong, 2 issues and the one that stands out is harmonic balancer....
