Oil Pressure Sender Unit

[Andy_J_G]

Right, gauge is up and down like an whores drawers and I assume its the sender unit, before forking out £53.20 (for a sender unit!) is there any way I can test mine to see if it is knackered or not? (Pre-serp 4.0, gauge has bolt on fitting, not spade).

Have you had a close look at the sender?
Mine had the same symptoms you describe and it was the sender. I replaced the unit as it went just before I set off for Le Mans last year but I reckon with a bit of patience I could have fixed it.

On top of the sender is the post you mentioned - is the post itself firmly fixed (glued) to the sender?
There is a wire attached to the bottom of that post and if the post isn't still firmly attached the wire takes the strain and all the flexing eventually breaks the wire.

The fluid pressure sender unit as in claim 16 further comprising an anti-modulating structure operable to control fluid pulsations and minimize wear on the electrical circuit.

sorry but what does this mean?

Does anyone know where to buy one for the best price?

I think it may be more a case of who has got one.
I got mine from what used to be TMS in Melton Mowbray. You could try phoning them because the guy I spoke to knew there were two different types and asked me which one I had - which I think basically comes down to the type of terminal on the top.

They are now knows as Prestige Performance Cars 11 Beler Way Melton Mowbray Leicestershire LE13 0DG Tel: [phone] http://www.ppctvr.co.uk/

Mine came from David Gerald at a reasonble price ( i.e. I cannot remember what it was, and I would do if it was high ).

Does the comment about who has got them mean they are difficult to get hold of? I would be surprised if these were not a standard RV8 part?

I got one for my pre cat around two years ago and it cost around £45+vat then. I got it at the TVR Centre in Barnet, Nth London.
