Heres what they said
Thanks for the email and link. We have to say that If the underneath gas tank is not protected mechanically or sprayed with a good quality rubberised protection coating on install, and then every year during its service to top up that protective cover, as we, the National caravan council and the tank Manufacturers say you must, then it’s inevitable that stone chips can cause any type of metal object like a gas tank to be damaged and corrode as in the link you sent us unfortunately.
If a tank is protected from the start ( as it has to be ) and then looked after every year, then you can get many many years out of it. We have autogas converted cars both in our business and privately owned ones by our staff with underslung gas tanks on them which are over 15 years old and are not corroded and are working fine but we check them and service them if needed when we service the cars. My own 1987 VW pickup was converted in 2002 to run on autogas and the gas tank on there is perfect with no corrosion, after doing 129,000 miles on gas. I only removed it to restore the car 2 years ago and I still have the tank and will be refitting it - this was sprayed it every year or so when it was serviced to protect it.
Here’s a link to it on our Knowledgebase with regards what should be done when installing a gas tank underneath. If people don't do this protection as it’s required to be, then its not the tanks fault if it get corroded and damaged.
(https://www.gasit.co.uk/support/knowledgebase.php?article=131) and as you might have seen it’s mentioned in every tank listing on our website plus we even give a free spray with every kit we sell directly. Here an example from our webshop ( https://www.gasit.co.uk/fiat-20ltr-euro-4-5-6-gas-it-system.html )
As a company we can’t do anymore than tell everyone it needs protecting on install before they buy them ( as per the product listing), then we go one step further by provide them with the actual underseal to do the protection and then we also tell them to check it year and provide this info on our knowledgebase and webshop. The tank Manufactures themselves also clarify this as it is printed on every tank certificate that comes with every new tank (and has done for the 35+ years we’ve been selling them) that the tank to be protected against damaged when used under a vehicle.
Hope this clarifies the situation and what we’ve known and been advising since we sold our first gas tank for fitting to a vehicle back in 1972.
I have given the new tank a few coats of thisRichard thanks for starting this thread it made me get of my bum and check mine . My nuevo has some protection from stone chips at the front from a coverd box section ,much of the underseal coating has washed off but the red tank looks OK. That gives me the impression that the gasit sealer is not very durable and should last longer than 12 months as it dose on cars . Not sure whether to stick to gasit coating or another wax free underseal ,if my van was newer I would look at boxing it in using something like a plastic engine under tray .
