fisha Posted September 7, 2005 Share Posted September 7, 2005 Was just wondering about this today ( too much time on my hands obviously ) In the RRC, the current tank leaks when anything more than £20 of fuel is in it. This isn't really a big deal as I run only on gas these days. I am shortly about to have the whole rear end of the vehicle apart to replace a section of the inner wings. I was planning on removing the petrol tank in order to allow me to stand on the ground inside to get better access ( the floor will obviously be out ) I was thinking whether it would be possible to make / get / fit a smaller petrol tank to replace the existing one. I would fit it to the front area of the existing one as that would leave me some free space to the rear to possibly allow a winch to be fitted under the floor in the future. So is it hard to do? What materials are suggested? cheers, Don. Quote Link to comment Share on other sites More sharing options...

Jon White Posted September 7, 2005 Share Posted September 7, 2005 Ah well...........I suppose you need to worry about armouring your tank when the only things its gonna get damaged by is falling off an axle stand............ Quote Link to comment Share on other sites More sharing options...

02GF74 Posted September 7, 2005 Share Posted September 7, 2005 i just made my own fuel tank from 6mm m/s, saves me makin a separate tank guard was this from scrach or you chopped the lower part of an underseat tank? any prep to get rid of the fuel inside? if from scratch, 6 sheets of metal or fewer sheets but folded? Any pics? Quote Link to comment Share on other sites More sharing options...
Diff Posted September 7, 2005 Share Posted September 7, 2005 I made a small tank for one of my offroad trials buggies. I used mild steel 1.6 mm sheet I seem to remember. It was three pieces(not including the baffles), which consisted of two ends with folded edges and one sheet folded to make the sides. The baffles are the same as the ends except with a few holes. The baffles prevent surge on cornering etc and help support the weight of fuel in the tank, so that the tank doesn't bulge. Still holds fuel 12 years later. Hope this helps, Regards, Diff Quote Link to comment Share on other sites More sharing options...
BogMonster Posted September 7, 2005 Share Posted September 7, 2005 You've been to the Barker school of fabrication! Nah. Nige would have used at least 12mm Quote Link to comment Share on other sites More sharing options...
robhybrid Posted September 8, 2005 Share Posted September 8, 2005 I have made 2 small 4 1/2 gal rear tanks to fit over each wheel arch in the back of a RR bob tail/pick up. I made them from 1.6mm stees and put 2 baffles in each of them. They had a triangular shape to the bottom of them so they would fit over the wheel arch on each side. They were used for 2 years without problems. I have also made one large 10 gal rectangular tank that fitted between the roll cage and rear tub bulkhead on a 88" hybrid and that is still going well 4 years on. The large tank has fittings in the top for a pick up pipe and return, and the 2 small tanks had hydraulic fittings welded to the bottom for fuel pick up.

Tonk Posted September 8, 2005 Share Posted September 8, 2005 i just made my own fuel tank from 6mm m/s, saves me makin a separate tank guard was this from scrach or you chopped the lower part of an underseat tank? any prep to get rid of the fuel inside? if from scratch, 6 sheets of metal or fewer sheets but folded? Any pics? i used standard tank top and remade the bottom in 6mm, just saved me makin all the holes in the top also moved the drain plug to the back rather than underneath. also made the bottom of the tank 2 inches higher. pics, errrr i'll take some but i've already fitted it Quote Link to comment Share on other sites More sharing options...
Les Henson Posted September 8, 2005 Share Posted September 8, 2005 You'll have to make sure you are an excellent welder as a leak will be a right pain - remove, empty, vent, re-weld, etc etc. I've replaced the bottom of a fuel tank before and it wasn't difficult work-wise.

02GF74 Posted September 8, 2005 Share Posted September 8, 2005 so all you tank makers, did you treat the internal mild steel surface in any way? I don't mean take it out for a chinese meal but to stop it rusting? Quote Link to comment Share on other sites More sharing options...
Tonk Posted September 8, 2005 Share Posted September 8, 2005 i didn't treat the inside of my tank at all, diesel is going in it so it wont rust anyway. mmmm chinese, nice idea Quote Link to comment Share on other sites More sharing options...
Diff Posted September 8, 2005 Share Posted September 8, 2005 I didn't treat mine, it was 1.6mm mild steel sheet and used for petrol. Still ok after 12 years. Obviously with any fuel system, you need to filter the fuel before it ends up in the engine!. I haven't looked inside the tank for a number of years, but it wasn't showing any serious signs of rust the last time I looked.
