Hi folks hope all is well :TU: Well Mrs P has been driving the Rav about a lot lately even doing some longish trips on motorways and it has been brilliant (TOUCH WOOD)  so much so that she has now decided once again to keep it a while longer. But she saw a video on Facebook the other day where the petrol tank was leaking on a 2002 model same as her own so panic struck again, "what if this happens to ours" she said, but I reassured her that ours was ok, well it was from what I could see last time I was under there. So my question folks is there owt that can be done to protect the tank? From what I remember it looked to have been coated in summat at some time but that was coming off in places and it was rusty but felt solid enough on the bottom but what the top is like who knows and could the top be coated with anything?? |

The RAV isn't known for rust problems generally. Having said that, any car is the product of its past care, or lack of it. if you have looked at the tank and it appears solid and generally unmolested then it probably is. If you want peace of mind you can always pressure wash (or steam clean) the tank and then give it a coating of Waxoyl, Dinitrol or ACF50. Rusting from the inside usually only happens if the tank has been allowed to collect water over a long period of time, like if the car has been standing unused for months on end. Even then, it can take years to rust through. It's probably an old wives' tale but many of my older generation mentors told me the best way to prevent petrol tanks rusting was to always fill them up at each fill so as to keep the inside of the tank coated in fuel; the petrol fumes above the liquid fuel helps keep moisture at bay. Could be rubbish but, rightly or wrongly, I've always done that. Personally, if the car is rust-free otherwise, I wouldn't worry about the tank rusting. F**kbook has a lot to answer for, IMHO.  |

Jim looking at the video the tank looks pretty well rusted on the outside? I doubt I would be able to do it so was thinking of taking it somewhere to be done and if I knew what Mrs P was doing with it long term might be worth getting completely undersealed underneath but don't wanna spend too much in case her mind changes again, which i'm sure it will :yes: |

It really depends on whether it is surface rust or more structural. The only way to be sure is to get it up on a ramp and have a good poke around with a big screwdriver and a ball-pein hammer. If the tank is sound then a coat of Kurust (or similar) followed by Waxoyl, Dinitrol or AC50 should solve the problem.
Alternatively check out your local rust-proofing centres and get a price for doing the whole car. It will solve your current problem and prevent future ones so you can just get on with enjoying the car.

OK folks so I got the Rav up on the ramps earlier and had a quick look at the tank, does the Rav have two petrol tanks?? Anyhoo this is the condition they are in they seem solid enough but Mrs P was watching and told me not to start banging at them so just tapped with my fingers for now. While I was under I noticed a drip on the floor, no not me(rofl) coming from the exhaust where there is a join but seemed dry round it and only wet on the thread. I suppose it is coming from the exhaust??    |

Hard to say by just looking at photos but the tank doesn't look bad. If the screwdriver/hammer test doesn't show any structural problems then I would power wash it followed by Waxoyl, Dinitrol or AC50. I still think it would be worth checking prices for a full professional treatment. Re the wet exhaust bracket, no idea. Steam condenses in the exhausted regularly so maybe a bit has seeped out through the joint if the nuts are a little slack. Doesn't look like a big problem. |

I suppose it is coming from the exhaust?? Looking at the fuel tank I would want to wire Brush the worst of the surface corrosion off and then treat it with some rust prevention and then gloss black. ...and the minor exhaust blow needs the clamp loosening and some joint paste put in and retighten clamp. |

The tank/s do feel solid Jim and I have had a look round at getting it done professionally but there doesn't seem to be any I can find on line in the Birmingham area nearest one is in Leamington Spa but they just use waxoyl. |

so much so that she has now decided once again to keep it a while longer.
