Oil pressure sender - really £69?

[taylormj4]

Hi All,
Anyone got a better source for the tiny sender unit for the oil pressure gauges on serpentine engines for the silver bezel gauges. Part number is N0126.

Can't seem to find it for less than around £69.

It has been debated to death on here. I suggest you do a search.

Buy the American made Isspro sender, cheaper yet far better quality than the ones offered by the TVR parts specialists.

Ask for an Isspro R8917-03, expect to pay about £35.00 delivered to your door.



Unlike the single terminal original that earths through the body of the sender, with your new Isspro R8917-03 you'll need to make up a short earth lead as it takes its earth from the second terminal. This is simple to do and gives a more reliable earth, a dedicated earth lead is actually an advantage.

For clarity is this the 0-100 psi Dave.

Having used a mechanical gauge to give me a more accurate reading I'm comfortable with the actual oil pressure so feel more confident to try one of these now

I'll be changing the oil shortly, I'll treat the old girl to one of these. I'm sure she appreciates my devotion

As stated above Alun you want Isspro model reference R8917-03.

R8917-03 is indeed a 0-100 psi sender which works perfectly with the TVR gauge. The -03 element of the part number relates to the isolated earth type as shown below.

• Range: 0-100 PSI
• Compatibility: 240-33 Ohms
• Thread: 1/8 NPTF
• Connection: 2 stud type terminals (Gauge & Earth)

Make up a small earth lead and connect one end to terminal "N" which is the earth, and the other end of your lead to the earth stud on your outrigger diagonal tube. You'll find a bundle of other earth cables connected here, so take the opportunity to clean up these earths and the stud itself.

The second sender terminal marked "G" therefore relates to gauge not ground.

The only other consideration with this Isspro sender is it's length, the unit is longer than the original, in order to get the thread started I needed to jack the engine slightly. Just taking the weight of the engine on the jack was sufficient, once started on the thread the sender screws in easily and with it fully seated on the taper the weight of engine could be taken off the jack and you're left with no chassis cross brace clearance issues whatsoever.

The Isspro R8917-03 sender is made better than the VDO brand typically offered by the TVR parts specialists, in my experience it also gives a more accurate reading as it's better paired with the TVR gauge. The use of a dedicated earth lead is more reliable than earthing the unit through it's body and finally the Isspro R8917-03 is half the price of buying a lesser sender from one of the TVR parts specialists.

Better quality, less leak prone, more accurate and way cheaper too... what's not to like?

I did wonder i it might clash on the bracing bars, I assume once it's screwed in it safely sits with some clearance.
Thanks for that. I'll try one
It's about time I checked my engine mounts and jacked them up a couple of mm then nip the bolts again.

Here's my nice new ISSPRO 0/100 psi oil sender.
Just need some oil and a filter now and I'll be trying this baby out

Nice find, another product on its way to a TVR parts specialist as we speak!

So just mine (no signal to gauge) just busy and these isspro ones are almost 50 delivered.

Anyone used a generic 0-100 psi one, not concerned about thread and diameter I'll use an adaptor.

Would this fit a 3.5 non-serp in the Wedge?
