To keep both stock oil pressure sender and aftermarket sender, what Tee fitting?

[alice]

I have been searching for some time now and of course read the merged thread about the oil pressure sender. My question is that I want keep my stock oil pressure sender as well as my new aftermarket sender. I know I need a branch tee but which one?

I assume it's something like a 1/8 Male BSPT to 1/8 female NPT tee but isn't the OEM sending unit BSPT? There for I would need a 1/8 Male BSPT to 1/8 female BSPT and 1/8 female NPT tee?

This picture makes it less confusing so let -
Red: 1/8 male BSPT into oil filter housing
Yellow: 1/8 female BSPT for OEM sender
Green: 1/8 female NPT for aftermarket sender

Any help is greatly appreciated!! Also it's a 2g OFH so if I got the thread size wrong, please tell me.

I don't think you're gonna find a Tee with 2 female 1/8" NPT ports and a male 1/8" BSPT.
You can however purchase one with all ports being 1/8" NPT and then get an adapter from Summit racing found <a href = http://store.summitracing.com/partdetail.asp?autofilter=1&part=ATM%2D2269&N=700+115&autoview=sku> here </a>.
Man, that's an expensive little bastard...

Its been a few years since I did mine (& the memory isn't what it use to be ) but I know I had a hard time finding a fitting that worked well. I believe its a 3/8" BSP thread but when I tried this fitting it screwed all the way in (being a parallel thread) & didn't like the sealing ring idea that it used. I then tried a couple NPT fittings (which seemed like what most used) & I didn't like the lack of turns you could get on these fittings before their tight. So what I did was order some spare oil housing plugs from the dealer, drill & tap the plug to the required size to install a fitting that would accept my Greddy sensor fitting. I then welded this fitting in place. You don't need to use a tee as there are a couple free spots that have plugs in them from factory on the oil fitler housing, that can be used. You could actually just do this to the stock plug you remove, but I wanted spares. I Installed the plug & the greddy sensor with some Permatex high temp sealent & has worked perfect for several years now.

I did this but I managed to find the fittings and adapters locally. I didn't know what sizes I needed so I brought the oil pressure sender units to the store and just tried a bunch until I found the right ones.

The total cost to me was like $10-$15 I think.

Thanks for the replies all. I probably piece something together at the local parts store.

Lets get some imput from those who have retained their OEM sender as well as an aftermarket sender. I know there are many that have done it.

Its easy, the plug towards the front of the car on the housing can be removed with an allen head and then my autometer sender was 1/8npt so I put some thread sealant on there and got it about 6 full turns in, works great

I've done it... WTF Did you not read my post?

Of course I read the post but I was still looking for some more ideas like remote mounting the senders and the like. Some people say they just tore out the plug in the front of the OFH and fit the sender in, some say it doesn't work.

I swapped my oil housing for a forward facing unit and used a sandwich plate. The sandwich plate has multiple ports for various things to plug into.

The engine vibration may kill the pressure sender and Autometer recommends that their senders be remotely mounted. The stock sender has a BSP thread as mentioned above. Summit Racing, Pegasus Racing, good local hardware stores and some speed shops have all the adapters.

Im not sure I would take this kind of advice from someone that recommends using nylon tubing for hot oil transfer. That alone is just a flat out stupid idea. Im sure the brass tee will last longer than the tubing.

I and several other friends have been using just a standard 1/8"npt brass tee fitting for years with no leaks, breaks, or any other issues.

I can get some pics of my setup tommorow.

Basically i took a 'T' off the oil filter housing.. then from one side ran a line into my drivers side wheel well (with oil cooler lines), went to a T mounted with stock sender and aftermarket sender, then from the 'T' on the oil filter housing i then ran a line to feed my turbo.

Anyways, pics tommorow

If one is to read the above recommended page it would be seen that both nylon and/or stainless hoses were recommended. Plastic would probably be fine, although I wouldn't do it, for a street car. Many cars have had gauges plumbed with nylon/plastic tubing. The page owner also has impeccable and distinguished record in car racing community.

I did browse the page and saw that he suggested either but he recommended the nylon. I personally have seen disasters caused from using nylon tubing for the oil pressure gauge. Its fine for use for a boost gauge but when used for oil, it is not uncommon for the nylon to bust and spill hot oil all over the place or worse. I dont care how distinguished his record is, that is just a flat out stupid idea. If you dont believe me, call any more reputable speed shop and see what they say about it. If you choose to use nylon tubing for that application, be my guest. Your not driving my car so it wont affect me at all.
