Thread: Making a Petrol tank

1. Should I make the tank bigger and if so whereabouts? Depends on wher it is and where you plan to go
2. Should I fit baffle plates? UM YEEESSSSS
3. Being made out of Stainless does this create any problems? It will add extra weight cause stainless is heavier than steel
4. What would you add to the tank which is not standard? Baffles

Thanks in advance

An anti-syphon baffle just inside where the filler tube enters may be helpful and a dipstick is always handy, especially if the sender unit is a pain to fit, or didn't work anyway.

I think stainless is as good idea as any other material,

Use rolled corners where possible so that there are less welds and sharp corners to fatigue crack, stainless is more brittle (slightly) than steel.

ie make a U shaped main piece that's flat on the bottom then add the ends and top.

Support tank with straps as opposed to welded on brackets.
Less likely to fatigue crack which 304 is prone to.

Probably how facyory one is so run with that.

Make sure there is a collecting point/ small baffled area around the fuel pickup to prevent starvation on slopes.

Will be using 316 Stainless.

Planing to make as few welds as possible. With very few at the bottom.

Like the dipstick idea.

Asked about a baffle plate(s) as mine does not have any!!!!

Anti syphon...cant believe people steal petrol!!!

Anti syphon-wouldn't it be easier for a thief to just unscrew the drain plug?

Or is the tank drain peculiar to my series (which granted has an aluminium tank)?

My rusted tank has a big drain plug in too

Aluminium fuel tank? I have never seen one of these. What vehicle is it on?
