Fuel senders

[dursleyman]

Putting a "new" fuel tank in my TR7 and I find I have two different kinds of fuel senders. It looks like one is an original type and one is a modern replacement.
They both give similar readings with a test meter so I propose to use the original type and wondered if anyone has thoughts either way?

The original type also has a rubber ring on the float (not shown in pics) which seems to be a bump-stop to prevent it hitting the bottom of the tank.

My original sender was as your top unit. It was still going strong, until the second time I pulled it out.

It did have a little petrol in the float, which I removed by drilling a small hole in it, shaking the fuel out, & plugging the hole with a bit of wood. This swelled as wood does in water & sealed perfectly.

It was still working when I pulled it out to do something to the tank, but not after it was put back. I had shaken the thing around too much, & broken the already well worn wire in the winding.

It was very well worn, so I would use a new one if available. Incidentally that wood plugged float is on the new sender now. When changing to a new tank I found the float on the new sender was about 1/4 full of petrol in about 3 years, & switched to the old one.

Before you refit either of them into the tank (to be forgotten for another 35+ years, hopefully) I'd recommend you
take that plastic 'will fill with petrol over time'-type float off and fit the VERY similar brass float from Ford.

An ordinary modern-fuel resistant O-ring will mimic the function of the by now old and cracking rubber ring...

Odd, I have seen the posts about the Ford float option but I seem to recall them referring to USA stuff, can you point me at the same item in Europe?

Not much of a trouble for decades of piece of mind imho...

Thanks Odd, I'll check them out.
Looking at their list it looks like it will fit almost all the British cars of the era so I bet someone here has them as well.
Watch this space.

1 caveat, people in the 6 crowd have had them come loose.
So you might want to tack on a little solder

Do use some care when tightening the lock ring.

It was after removing & refitting my sender recently that my 7s tank started leaking between the main tank, & the fitting the sender fits into.

The lock ring was tapped quite gently, with a drift & a small rubber hammer, not hammered wildly, but it broke the solder seal.
