Richardtr3a Posted June 21, 2020 Report Share Posted June 21, 2020 As part of lockdown and self isolating I am out in the garage every day. This means that I am on the forum everyday as well. While I am waiting for my new exhaust I started to clean up the boot. After removing the panel I could see the petrol tank and there was some sticky residue from the filler down the back of the tank and along the floor. It must come from filling the tank with petrol from a can which splashes around a bit. I never know why the filler does not line up with the inlet by at least 1 1/2". The question is now whether to get the inlet cut out and welded back in a better position and then renew the rubber connector. ?? Will this damage the tank ? Is it safe for the welder? How should I clean it before welding and what to seal it with afterwards? I did use a tank sealer once but can not remember what it was. Thanks for any advice Richard & B.

BlueTR3A-5EKT Posted June 21, 2020 Report Share Posted June 21, 2020 Filler alignment to tank is an issue I have too with both the leaky original tank and the Alicool replacement. Ignore it. I wedged a bit of timber under the tank to tip it so the two tubes lined up better then did up the tank straps. Moving the filler tube - The welder will probably refuse. - Will it make the car go better? If not, do not mess. Peter W Quote Link to post Share on other sites
RobTR3 Posted June 21, 2020 Report Share Posted June 21, 2020 If you want to move the filler neck on the tank you should take it to a specialist who will soak the tank overnight to clean it out and make it safe for welding. By specialist I mean radiator/fuel tank repairers who know how to deal safely with fuel tanks. They will also pressure test it as part of the job. If you are out by 1 1/2" on alignment with the filler cap neck, you may have to tip the tank up quite a bit off the boot floor. I assume you will be tipping the tank forward towards the front. You need to consider then whether the float on the fuel sender unit maybe at a crazy angle and may bang against the side of the tank because it is not perpendicular within the tank, as well as perhaps giving an incorrect reading.

Ralph Whitaker Posted June 22, 2020 Report Share Posted June 22, 2020 I found that the filler on my tank was out when I offered it up to the car. Rectified by using bits of rubber exhaust strap, about 12mm thick, under the tank between the tank and the brackets, this lined it up perfectly. Ralph Quote Link to post Share on other sites
Richardtr3a Posted June 22, 2020 Author Report Share Posted June 22, 2020 I have researched tank welders locally and the best answer is to leave it alone and find other areas of the car to improve. Thanks for the advice. Richard & B Quote Link to post Share on other sites
