Fuel Sender Gasket 280i

[PelleTVR]

Dear all,

I need to replace the fuel sender gasket (Tasmin 280i convertible). Does somebody know the origin of this gasket?
Are there any things to pay attention to when doing this job? (First of all battery should be disconnected... )
Every hint is very much welcome.

Thanks a lot
Ralph

Always good practice to disconnect the battery, whenever you're working on the car.

Hi PelleTVR. Please let me know how you get on, gasket etc as it's a task for me this winter to correct my fuel guage which refuses to register more than 1/4. I'd like to think it's just the gauge but I'm sure I'll end up replacing the tank unit. Are they available? J C.

I did this job last week with a gasket from TVR Parts (& a tip from Neil at ML). If your sender is the same as mine, the item you need is L0174 . When you offer it up, it may be that the holes don't line up. Rotate it until they do. Mine worked with the notch at 3 o'clock. Give there are 5 holes you might expect them to be 72 degrees apart. It's TVR so they aren't

Thanks Joe. Might be in the market for a sender as well. J C.

Hi v8s4me,

sounds good that you are the pioneer in doing the replacement.
Did you empty the tank or just lower the level? Is it easy to fit the sender again? I mean, it should be placed correctly in order to get the right Information....

Thank you!

The tank was off the car so it was very easy to fit. Good luck it you're trying to do it in situ. You do need to make a note of which way it is fitted to the tank so you put it back in exactly the same place. Just use a felt pen to mark the tank and the sender back plate before you take the sender out.

Mine was a Stewart Warner one, with 6 bolts (or 8?). It started leaking slightly, and sender got jammed (the contact pip came loose). I repaired sender and ended up making new gasket out of gasket paper and using fuel proof gasket sealer, and managed to do it all in place without moving tank. It's a bit tricky but doable. Not had leaks since.

5 bolts on mine ...



The picture shows the old gasket.

While I was at it, I tidied up the wiring and put a waterproof connector in the cabling to the sender unit so that it will be easier to remove next time.

Where did you find/use for a new sender? Grady

Did measure my SW sender, and it's calibrated about the same as the Triumph (Smiths) ones, so older bolt on senders from stuff like Triumph Herald, Morris 1000 ? would probably work... Newer Smiths senders had a kind of 'clip and lock' setup with a rubber ring seal.
(e.g Triumph saloons, Dolomite, SD1).

Not sure exactly which is what, but SW appear to use same resistance ranges as Smiths for both their temp and fuel senders.

Joe,

It is normal for the bolts not to be symmetrical. For once, it's not a "TVR Thing".
