DIY fuel tank

morrisman1, Nov 3, 4:05am
Any ideas of a donor container! I need to hold about 15L and needs to house the pump too, which is about 150mm deep. I thought of using a stubby gas bottle but they weigh quite a bit.

Any ideas!

yes car is fuel injected and I am using the original tank module to keep costs down.

Convert a outboard tank or portable fuel tank

Mini Keg! oh yea, they would be perfect if 10L and I could have fun emptying it first.

The chemical drum sounds like a good idea, Ill look into one of them.

Is this for a road going vehicle!

No its not road going!

I had a look in the shed and a morris minor sump is damn near perfect! I will need to weld a flat sheet across the 'top' of it and also fill up where the main bearings sit. Dimensions are good and capacity is about right too.

a sump from a morry! I though you were trying to save weight!!

just use a plastic bag. the pump will fit ,the wires and fuel line can come out the top enclose with a rubber band. cheap. yes, easy to get.yes, what more could you wish for! edited to add bigger capacity get a bigger bag. the ultimate fuel system.

How about an alloy fire extinguisher!

Wouldn't those be cast iron! Horrible stuff to weld. Not to bad if you bronze it up with an oxy/acet set though.
Plus petrol is really good at finding pinholes and porosity in weld seams so if you do go that option, at least make sure your seams are good and have as few stop starts as possible.

Why not use a motorcycle or quad fuel tank.Many of them have the fuel pump incorporated, and you will probably be able to pick one up cheap from a wrecker.Many bike shops wreck quads, so that may be a start.

Righto, I have a solution. I can use the original 121 tank with a bit of modification. I have had to make the hole in the top larger to accomodate the pump module and I have also had to make a surge chamber for the pump to sit inside. The 121 tank surprisingly has no baffles in it which would make it terrible for the injection pump if it had no surge chamber.

the tank is much larger than I wanted but it will do.
