Fitting an Oil Pressure Sender

I'm looking to fit an oil pressure gauge to my 3.5 V8. Do I have to put in a T-piece to use the port the pressure switch is in at the moment or can I use one of the other ports on the filter housing?
There isn't much clearance between the filter housing and the steering box, so I'm hoping one of the other ports also tap into the outlet side from the filter. Here is a piccie:



Can I fit a sender to the port indicated?

Usually the T piece is screwed into the block where the oil pressure light switch is - the light switch is then screwed into the end of the T piece and the sender is screwed into the side of the T piece - thats how i fitted mine on my 300tdi

Thanks Daz, but the problem is there is not enough clearance between the filter housing and the steering box on a V8 90 to put a t-piece in where the pressure light switch is. I was therefore hoping to use the other port?

Then use something like this

Yeh, I've thought about those, but it would be cheaper and easier if one of the other ports was useable on the pump housing

Probably but is there oil pressure behind that plug - or is it just a drain bolt??

That's the nub of the issue - does anyone know?

You could ask MR NOISY as he's got a v8 in his disco with oil pressure gauge fitted

Have a looky at this. http://www.landyzone.co.uk/lz/f42/aftermarket-oil-pressure-gauge-103425.html
I had the same probs. Might help you out

Thanks Harleyman, looks like this port is ideal.
