I have a steel heating oil tank with a vertical 4ft x ½" sight tube
showing how full the tank is.
Unfortunately, the tube has become cloudy over time and is very
difficult to see the oil through it.
I guess that my options are to clean it or change it.
Are either of these options ones that I can do myself or should I get
a heating engineer to do it? Seems expensive to call out someone to
fit a £20 piece of tube.
I just wondered if anyone had a similar experience.
I would just buy a piece of clear plastic tube from the local hardware and
fit it myself and I would expect to pay a lot less that £20.
I always keep the valve at the bottom closed. Normally I dip the tank to
check the level.

As one should in case the sight tube fails and you deposit a few
hundred litres of expensive heating oil onto the ground.
Top of our tank is a good 8' above ground level. One could dip it but
it's easier to open the little sight tube valve and see the level.
Or if it's like mine and mostly shrounded in a metal sleeve just
rotate it in the sleeve. The cloudyness is where the light and oil
has got to it. I think I did have to end to end it as well as the
plastic had become to hard to form a proper seal on the spigot after
yes 3 weeks ago.
Alas, tale of woe, urgently needed to order oil but sight gauge was

Also the old one had a lever valve (always on) at the bottom - new
ones have a push button which has to be pushed to admit oil to the
The tank here has a wheel valve between the tank & the gauge, so the
gauge can be removed without loss of oil.
The large new nut (which came with the new gauge) for the bottom of
the gauge was discarded as I decided to reuse the old nut. But that
was stiff to remove. The new tube thread into the large nut needed
sealing - I used a car gasket compound (Hemelite) - but prob most oil
proof sealants would do.
The oil came with free advice from a cheerful delivery driver. Best
refurbishment method is to replace the old tube with milk parlour tube
available from agricultural merchants. He said that it doesn't
discolour. He recommended sealing the tube to the nut at the foot
with a jubileee clip.
