JimAttrill Posted August 7, 2008 Share Posted August 7, 2008 We have a 110 in with a leak at the top of the tank - most likely the fuel pump or the pipes. Unfortunately the tank is full so I suggested to the owner that we cut a hole in the floor instead of taking the tank out. My question is, does anyone know EXACTLY where to cut the hole?

BogMonster Posted August 7, 2008 Share Posted August 7, 2008 Jim there is a post somewhere on here by GBMUD giving measurements for this very reason I thought it was in the tech archive but not 100% sure about that. Quote Link to comment Share on other sites More sharing options...

JimAttrill Posted August 7, 2008 Author Share Posted August 7, 2008 I should have looked there first! Thanks Steve. Quote Link to comment Share on other sites More sharing options...

JimAttrill Posted August 7, 2008 Author Share Posted August 7, 2008 Question: how do I make a hole in the floor without drilling through the tank by accident? That is, what is the clearance between the floor and the tank? Maybe I should use a drill with a spacer so that it can't go far into the floor?

BogMonster Posted August 7, 2008 Share Posted August 7, 2008 I think you have a couple of inches clearance because there are ribs under the floor IIRC and then a space under that but yes a drill bit with a bunch of washers on so it can only just go through the floor would seem to be a sensible precaution Quote Link to comment Share on other sites More sharing options...
yellow Posted August 7, 2008 Share Posted August 7, 2008 Cut with a Dremel... (Small disc grinder) But make sure that although you are cutting Aluminium the sparks or hot cuttings do not reach the spilled fuel. This safety goes for drilling as well...

BogMonster Posted August 7, 2008 Share Posted August 7, 2008 Also beware of thermite explosions when next cutting steel with the same tool Quote Link to comment Share on other sites More sharing options...
GBMUD Posted August 7, 2008 Share Posted August 7, 2008 I used an angle grinder to cut the hole in mine, there is easily sufficient clearance under the floor - 50mm+. Once through the floor I was able to remove the floor 'hatch' (had to break one or two spot welds on the ali IIRC) but had to use a reciprocating saw to cut through the strengthening under the floor. Since I have a store draw in place the strength of the floor is irrelevant to me but you may wish to keep it in mind Jim - some rivets and angle iron would readily replace the strength IMHO. If you are only looking at loose connections you may get away with leaving the strengthening in place. I had to remove some so that I could change the pump.

One of these days we must get a fire extinguisher for the workshop. I think a UK H&S inspector would have a heart attack if he saw our 'workshop' Quote Link to comment Share on other sites More sharing options...
