Fuel tank sealant
Posted: Sun Nov 18, 2018 7:00 am
Hello everyone
Yesterday being crisp, dry, sunny and cold here in Munich I took the Daimler out for it's last run of what has been a very good season of Daimler motoring, also made a nice change to operate and enjoy the heating system overhauled two years ago...it was almost cosy!
I reluctantly bid the season farewell untill 2019 and raised the saloon on the car lift in our workshop and got stuck into the first of the winter projects, removal of fuel tank.
I have obseved for too long the rust inside the tank when refuelling and I believe has already caused fuel pump failure 3 years ago so it was time to act.
The tank was removed without drama in about 30 mins, I was amazed and very pleasantly surprised to discover no rust present in the floor/luggage compartment pan from below upon removing tank.
A sort of underbody treatment has been applied at sometime and has been very effective as with the rest of the underbody. I would be interested to know if that was applied during manufacture or subsequently by someone before me who did a very good job. I believe I have just removed the tank for it's first time, when installed on the production line they clamped the vent pipe between one of the mountings and tank, no wonder there was often a smell of fuel in the passenger cabin, should I bring it to their (Jaguar's) attention regarding guarantee or compensation?!
Sender unit was removed as was filter assy, latter was no longer performing its function as filter had partly detached itself from plug and pick up pipe was full of rust, amazed car actually ran.
The amout of rust inside tank is not as bad as I was expecting and not too much came out during flushing procedure.
I am very tempted to attempt repair of tank by relining with "POR 15" Fuel tank sealing kit, it got a good write up in Practical Classics a while back, have any of you experience with this or altenative product?
I shall be sand blasting the exterior of tank which has same underbody treatment previously desribed to assertain all round integrity or presense of near penetrative rust holes etc before proceeding or making a desision.
Having read on the old forum more that once of the quality of very expensive replacements which sometimes do not fit!!! I want to attempt a rescue of original tank by chemical relining unless you fellows have had an unsatisfactory experience with these kits and would counsel caution.
All the best and much success with you Daimler tinkering this winter!
