ETB oil pressure sender required
andyace - 31/3/18 at 09:02 PM

Hi all,

I have a 2.0 Pinto and need to get an oil pressure sender for my electric ETB oil pressure gauge (90psi 0-6 bar)

I think the one is like the one in the link below .... seems rather expensive !! anyone know if there is a cheaper alternative ?? (needs to be 0-6 bar)

Thanks

Andyace,

For a brand new actual OEM part, I'd say £33 inc the VAT is pretty reasonable...

VDO senders are anywhere from £50 - £110. (Just replaced mine the back end of last year.)

eBay have cheaper after market ones for around £20 up over but you take the risk of poor imports not to the OEM spec.

For the sake of a £13 saving... I'd go for the OEM part every time...

Thats the one I have fitted to a gauge and also gives me a light on low pressure (too late though) hence why I use the gauge.

As said, £33 isn't too bad I thought.

Thanks guys,

yeah having looked around I think i'm coming to the same conclusion, don't fancy bodging in some import sender

Looks like it's time to bite the bullet .... that's a chunk off my £250 budget for the car

As far as fitting an oil sender, should anything be used on the thread ???e.g. PTFE tape to avoid any leaks ?

If the treads are good you shouldn’t need to use anything.

Definitely do not use anything on the thread.

The thread on the sender is tapered I.E. NPT... It will seal.

The sensor works using a resistor to earth. If you make a higher resistance between the sender and your engine you will get a false reading on your gauge, a higher pressure reading.

A dead short to earth = 0 bar.

Open circuit or very high resistance = Full, off the scale pressure indication.

Hope that makes your decision easier for you...

I had an issue with mine last year, need to do a write up on it as It was a bit of a learning curve at the time.

Thanks Ian, that all makes good sense, I need to also use the adapter to take it up to 1/4NPT as its a 1/8 sender.... so nothing at all on the threads for both adapter and sender, cheers

Like the above?
Yeah, both tapered treads. No ptfe or paste.
Clean metal to metal to give good continuity for chassis / engine earth.
If there is any oil weeping, just give it a further nip up.

Got this written up tonight. Might help.

Cheers.
