Sawing aluminum tanks
For some reason when two aluminum tanks were installed just three years ago,
they chose not to put fuel guage senders in. So now I need to install them. The tanks hold diesel fuel. I'm concerned about the danger of an explosion as I saw the holes. What do people do? I'd never try this with a gasoline tank but am unsure of diesel. |

I have welded diesel tanks that were emptied with no issues many times. If you are really worried, use nitrogen or CO2 to inert the atmosphere inside the tank. If there is no oxygen, there can be no flame. I'd be more worried about the chips in the tanks than any fire hazard. -- “TANSTAAFL” “All I can say is there had better be some cheese at the end of this maze……” __________________________________________________ __________________________ "A prudent man foresees the difficulties ahead and prepares for them; The simpleton goes blindly on and suffers the consequences." - Proverbs 22:3 |

Sawing aluminum tanks
There is a very small risk but you have several things in your favor. A
hole saw on aluminum doesn't produce sparks, the aluminum does not get very hot and diesel has a relatively high flash point. That said I think I would purge the tank with CO2 or nitrogen first. Also the aluminum chips can cause a real problem in fuel pumps. . -- Glenn Ashmore I'm building a 45' cutter in strip/composite.

Because it is reliable. Difficult to say the same for instruments on a small boat (100 ft or less) without spending some very serious money. Ask the US Navy when they install level measurement instruments on their vessels. Lew |

Sawing aluminum tanks
Hi there not to worry we do it all the time in the truck repair shops. Use
the proper sized hole saw with grease on the teeth and drill away. Their may be a few chips fall into tank but they are picked up in the filters.I have done it an hundred times with full or empty Diesel tanks. Sal "Jim and Becky" wrote in message ...

It is very tough to beat a stick for level measurement.....unless the boat
