What metals are ok to use with wvo?

[Classicfordguy]

Thinking about how to set up my truck for wvo and am not sure some of the materials I want to use are ok.

was going to make my tank out of steel, probably 60 gal in place of my 20 gal rear tank.

Fuel pickup out of either aluminum or steel with a copper coil through the middle using brass fittings. (coolant circulates inside the steel tube while oil is sucked through the copper tube).

So any idea if any of these are bad for bio, coolant, or diesel?

Steel
Copper
Aluminum
brass

Thanks,

use cooper to circulate coolant through.It conducts heat better than steel.Not to mention it wont runt out from the inside.Steel or aluminum should be fine for both the pickup tube and the tank...

If you use steel to make a tank be wary of polymerization caused by veggie oil. Fat and such will build up on the tank walls and corrode and rust and such. Weve converted factory steel tanks to heated wvo tanks and that could be a problem sometimes. My brother made a steel tank and used a coating made for fuel tanks to prevent corrosion and it works like a dream its called Tank Kreme
