Richard, BWM did try plastic fuel tanks in 96/97. They had a quality problem and the tanks melted. Result cut console out and replace with stainless steel at the manufacturers expense and down time to the owner.

Agreed S/S tanks do have condensation problems, however that aside properly made they will last for years. There are other materials as pointed out in a series of posts last winter however cost and availability is probably an issue.

To solve the condensation problem, keep the tanks full and fit a good water separator. Oh and just use it regularly

Vetus make a tank hatch which has filler, breather and fuel lines etc all in one 6" plate which bolts into the tank and has proved very effective. It means you can then take it out and inspect the inside of the tank.

*Update*

OK mechanics the bringers of bad news

A bolt on top of the inlet manifold has vibrated lose. Consequently it has taken (read blown) the gaskets on the reed plate and the top two carbs. So as everything wasn't 'sandwiched' together it caused bad flow at low revs causing the 'sneezing'.

Parts about 45 gaskets
labour 2 hours

So a bill of about 130, but i should be back in the water for the Herm cruise

Fuel Tanks

Hi All

Scorpion use fibreglass tanks and allways have done, the tanks have a large inspection hatch which you can get to through a deck hatch, never had any problems at all with them, seems to be the way forward.

We all know that stainless steel sweats and esspecially so in this weather we've been having and this effect introduces water into our petrol.

Although there may not be much weight difference between plastic and stainless there certainly is a large price difference between the two.

And you dont get any of the problems of fuel contamination associated with stainless steel.

On my Zodiac the 80 L tank is made from plastic ( I think). One has to assume that a company with as much experience as Zodiac know what they are doing. Why dont other builders use plastic tanks ?
