Hello to all and hope you had a good 4th of July, now back to work for me.
Ordered and received the parts to rebuild the 4-108.Have sent off the parts and peices to the machinist to have him press in what needs to be pressed. However now that the red beast is out of the way I have removed the fuel tank. There were small pin holes in it so I took it to the welder to fix it up.He welded the holes and put 1/4 sacrificial strips were it comes in contact with the wood.It is a aluminum tank aprox 1/4" thick and about the same size as the original.He couldn't plug all the holes to pressure test it.If I can I will but do not know how many pounds of air to pressurize it too and how long should I leave it pressurized.Has anyone ever had to do this?
Passingwind,I had Florida Marine Tanks make me a new tank back in April. I was told they pressure test the tanks at 3to 4 psi no time under pressure was discussed.I would think if the tank would hold pressure for a couple hours that should tell the story. Allen
Pressure it up to test pressure and soap test it. Use dishwashing liquid and water. Apply it with a spray bottle or garden sprayer. If it don't blow bubbles, it ain't leaking.
Did the soap trick and found the leak it was returnd today to to get done again and I gave the welder the presure gauge and the spray bottle of soap water.Thanks for the info everybody.
