Oh yes, didn't even think about it.

I missed the sarcasm in the tone of his typing, hinting at the wonders of Opti fuel consumption i presume.

Taxi for one please...

I'll get me coat!

Uncle Al, sorry to have missed your call, day off with Barney today and he had taken my phone off the table!

So, bearing in mind the regular loose type tanks could be an issue (and as Unlce Al said, may draw in air and damage injectors etc) so, what type of tank could I use? Ebay has plastic tanks for underdeck use....presume these wouldbe okay strapped down securely on deck (can utilise the floor dowls we use for the removeable jockey seats for fixing straps etc)....

Something like this? http://cgi.ebay.co.uk/FUEL-TANK-PLAS...item1e5eed0301

Any other suggestions appreciated!

Thanks, Dan
International Marune Supplies have a great selection of inboard & portable tanks and all the other kit you may need to add a fuel tank.

Think you dropped a washer on the a frame foot, is that for one of the other 3 bolts? or from the fuel filter mounting plate?

The a-frame was just temporary positioned at this stage. You may notice there's no hole drilled in the deck either

Indeed, i only noticed it as i had my A frame off at the weekend after finding it leaked - due in no small part to the chuffin great bolt holes that went all the way through to the outside

So bucket loads of Sikaflex later problem solved -then i noticed a spare washer, just like in your photo - back off again and more sikaflex problem resolved.

Optis - seriously - damage injectors & get nasty air locks if it runs dry?

I would hope the emissions gubbinry would detect it going lean & shut down before injector damage occurs, and if there is no vent / return line to the fuel rail well...... someone in Merc's design team needs a slap!

If this is a serious issue, all you need is a flow sensor on the portable tank line. I;ve seen NMEA 2K ones on a website somewhere, so you could fit one near the tank (so that it detects no flow wit ha safety margian in the pipe) and set an alarm on your plotter.
