fox889 Posted November 22, 2012 Report Share Posted November 22, 2012 Well, removed the tank on my '73 '6' today as part of a program to re-position the Bosch pump under the floor on the outside. Why remove the tank? I had issue's over the summer with the old girl spluttering or even cutting out in extreme hot weather, various causes were put forward by the kind gents on here, one of which was debris of some kind inside the tank hindering the flow. Tank removed, fuel drained (clear as a bell) sender unit removed & what's that rattling?.............previous owner had dropped one of those lead bags in the tank (not sure what you think of these things). Had a good look around the inside with a pencil torch & all looks good. Yes there's a slight piece of corrosion on the bottom of the tank where the two halves are joined but apart from that she's ok. What did surprise me was, that over the feed outlet is what can best be described as a metal bowl with a metal tube that goes to the top of the tank & one assumes is the feedback from the MU? I was not expecting this bowl covering the outlet, I'm guessing it stops debris/pices of rust etc? I'm not convinced that applying 'slosh' or similar is a good idea now as there can't be that much room between the tank casing & this bowl, any sealant would minimise this gap? The lead bag is a good/bad idea? I've been running her on V-Power + Castol valvemeaster & now this lead bag....good/bad Is this 'bowl' covering the outlet original Slosh it or leave it? I was going to have the tank flushed & checked by an independent radiator specialist, not sure now! Appreciate people's thoughts on this, two or more heads are better than one! Best wishes Nick.

ianhoward Posted November 22, 2012 Report Share Posted November 22, 2012 Nick I use V-Powere when avaialble and also Valvemaster plus on what I understand to be the original head (i.e. not converted) and - touchwood - have had no issues at all. As to the merits of those 'bags' of lead shot... Hmmm - not convinced!!! I seem to recall posts on here about them - not particularly favourable comments towards them either if I remember correctly!

fox889 Posted November 22, 2012 Author Report Share Posted November 22, 2012 Thanks Ian, I'm also slightly concerned that she's been on a 'double-dose' of lead substitute for how ever many years, whether you can do any harm with a double-dose, I don't know!

peejay4A Posted November 22, 2012 Report Share Posted November 22, 2012 I think those fuel treatments are tin based, nothwithstanding the dubious science behind them. Quote Link to post Share on other sites
AlanT Posted November 22, 2012 Report Share Posted November 22, 2012 Are people putting Lead-shot in the tank because "Lead" has been removed from petrol? If so, then this is wrong. There never has been any Lead in petrol. The additive was Tetra-ethyl Lead. This is like sprinkling your lunch with Sodium chippings and giving it a squirt of Chlorine. Al.

peejay4A Posted November 22, 2012 Report Share Posted November 22, 2012 No, it's tin. Quote Link to post Share on other sites
