Preferably one that will have experience with the ins and out of fuel tanks, breathers and filler locations and baffles etc. The Totes have been fine, but want to increase the range and free up space at the back for Live Bait Tank, plus just don't use the rear underfloor storage. |

From memory, they also do steel tanks as well, also supply on a regular basis one or two most reputable glass boat manufacturers. Canon Place, Pakuranga , phone - 577 1285. |

This meant any spills could be contained in the well rather than in the bilge or on the floor of the boat. I too would go along with breathers at opposite ends of the tank and the higher you can go with breathers and filler pipe the less chance of a spill. The important thing with the breather is for it to rise all the way from the tank to the fitting, easier said than done sometimes. In a perfect world breathers should be about half a metre above the top of the filler pipe but on a small boat this is virtually impossible. |
Reelcrazy wrote: One thing that should be done is to pressure test the tank before installation. 2 or 3 psi is more than enough and can be achieved by a temporary extensions on the breather(s) and filler pipe. With these test pipes every two foot of length vertically will result in 1psi of pressure being applied. Easiest if done with water just dry the tank out again afterwards, a hot sunny day is usually enough although methylated spirits can work pretty well too. Don't do what a friend of mine did and capped off the outlet an plugged in his compressor at about 5psi there was a loud noise and the tank had a bulge blown in it. |
