Fuel Level Sender Units Filling Cap


In cruising, you travel from country to counrty where environmental laws are increasingly becoming more strict. But we all want to look after the environment, right? Fuel spills are a serious mater and there are various ways to minimize these. Also, when under way, one sometimes has to top off the fuel tanks from Gerry jugs. This is made all the more harder if one has to do this on deck with rain or sea water washing over the deck.
(In one passage we carried 17, five gallon Gerry Jugs as well as our full 100 gallon tankage. We used all but 25 gallons in that passage in which we also endured a BIG storm. This system helped to do fuel transfer much easier, when being on deck was life threatening)
We installed, on each fuel tank, a filler cap, and while we were at it, installed a sender unit for fuel gauges. These were purchased through WEMA , a company that supplies sender units. As an aside, we also installed one of their special sender units on a holding tank; but have to report I'm less than happy with it due to it having to be cleaned periodically. A task I don't enjoy. But the Fuel sender units have been flawless and I can recommend them.


To cut the holes for the fittings, we used a regular hole saw found at most hardware stores, using some cutting fluid to help preserve the hole saw. I think we got about 5 holes cut before I had to purchase a new hole saw, which was cheaper than getting them plasma cut. Each item was sealed with an RTV automotive cement which formed the gasket and was impervious to diesel.
Now, I fuel the tanks from inside the boat to minimise the potential for a fuel spill into the ocean. The same applies with filling from gerry jugs. And of course, I have a very quick way now of checking how much fuel I have without the need to "dip" the tanks. A task which requires getting under the floor boards if done.

B G Type C mast head units are better



Better than what?

Well I posted a blog in November 2011 about a wind speed instrument I donated to the HBYC marina section, really it was a trade with Chris, from yacht Faraway and for his old B&G Network instuments so that the club could have a winspeed indicator.

Not a bad trade, I supply the windspeed indicator and I get the gear he was replacing, well here we are two years plus later and guess what, its still working!

The old Type C  B&G mast head unit, it must be at least  twenty six years old but the grey control box that powers it was thirty six years old and that was two years ago!

From the November 2011 blog.


HBYC Marina gets a 60 knot wind speed indicator

We often have members asking what our wind speed is recording,seems to me if its windy on the marina,its a sight more so out in Hout Bay,so to enable any member or visitor to see the wind speed,the club now has a B &G mast head unit in place,its the C type and with a matching 4" (100mm) gauge,which has a bonus in that it reads to 60 knots,as the later series Syncro types only read to 50 knots. (only?)

As I have seen two later and still the current 213 MHUs fail in three years and Chris supplied me with his two later 496 units, also not working, it stands to reason the older units are longer lasting?


Just how old is this, thirty years plus will be my guess!

They were released in 1972/73 and discontinued in 19886/87, so we can have an age as old as 41 years to 26 years old?
So their old mast head gear is better than the newer 213 and 496 mast head units, why is this?
