Default Where can I purchase...

a 1/8 BSPT tap and a 17mm Crow's Foot wrench? I'm trying to install a Defi EGT and oil pressure gauges and I can't find these tools for my life. I can find NPT but not BSPT (PT). Nobody seems to know what a Crow's Foot is either. I've gone to Lowe's, a few local hardware stores, Autozone, Pepboys, and Sear's Hardware and have had no luck whatsoever. Is there somewhere where I can just walk in and pay to have the piece drilled and tapped? I know I'm not the only guy with Defi BF gauges so where did you self installers find the equipment?

1/8 BSPT:
Instead of finding a tap, why not get the threaded plug from Subaru and BSPT - to- NPT adapter? www.mcmaster.com should have fittings that are compatible.
Some auto specialty hardware stores would carry them as well. I'm not talking about Pep Boys, AutoZone, or the CSK group franchise though.

Alternatively, www.wrxtra.com has a kit for installing metric-tapped senders to the oil galley plug.

Crow's foot wrench:
Granted, removing the oem oil galley plug on the top of the engine block to install oil pressure sender is very inconvenient without them, but it is doable. www.wrxtra.com also has some useful documentations for this install. Fwiw, using a 17mm allen key + wrench (for leverage) could work.

Thanks for your reply. I actually do have the Subaru oil galley plug which happens to be in BSPT so oil pressure gauge is not really a problem besides the Crow's Foot. My concern is tapping the manifold for the EGT. The EGT probe is in BSPT and I'm not sure if I can find an adapter for a probe. As for the Crow's foot, I thought that was used to install the sender to the galley plug, not to remove the original plug. I guess I better re-read the instructions.

I see. Well, there are up-pipes that can take the oem probe + aftermarket, but I don't know whether the aftermarket bung is BSPT threaded or not. (Example I Googled: http://www.exhaustdepot.net/ewrxupwifl.html ) Maybe that route is simpler than permanently tapping the oem up-pipe for an extra probe.

As for the 17mm crows foot wrench, iirc, it is to remove the oem blind plug. Once you remove it, the oil galley plug replacement has a hex outer shape that uses a bigger & more standard sized wrench. It's been a while since I've done this, so I could be mistaken. One thing for sure, I managed to remove the oem blind plug and install the oil galley plug + BSPT-NPT adapter + sender without the crow's foot wrench. Using one probably makes life a lot easier, as many have mentioned elsewhere.

One thing to bear in mind is to be careful when you tighten. It is extremely difficult to extract a broken fitting / plug / parts due to overtorquing.

Got mine at Sears (in kit). Assuming you're installing the oil pressure sensor w/ oem plug at the firewall side of engine? Best spot IMO. Crows foot very nice for this task.

Please post details when you find the tap...my Defi EGT is still (one year later) not hooked up...mostly due to "lazy"

Thanks again for your reply. Reading thru the instructions, I never really saw any torque specs. How much torque are we talking about here?

Brentlz-I went to my local Sears and they looked at me funny when I asked them but I probably should have asked someone else. I'll give them a try again for the Crow's Foot. And yes, I intend to use the oem galley plug and tap in right under the intercooler. As for the tap, I'm still looking

The kit I got from Sears is "Craftsman 10 piece Metric Crow-Foot Wrench Set 3/8 Drive" The part # listed in upper right corner of the bag is 9 4363 (the "9" is underlined & smaller than "4363").

I never found a torque value for that fitting in the manuals...just tightened it by feel...Not "super tight", just turned "a bit" past when the galley plug made contact with the crush washer.

NO....that is an allen key.......the sender is installed in the new plug and then the new plug with the 17mm hex that requires the crows foot is installed in the block.

If you are using the rear galley plug('under' the IC), as SOMEONE else pointed out in a different thread.......you can remove the IC and the passengers side IC bracket and use a 17mm wrench to install the plug with the sender in it THAT way.

Ah, I remember now. A regular 17mm wrench has hardly any clearance to maneuver even with the IC removed, but it is doable.

As brentlz mentioned, just make sure it isn't overtightened. Perhaps the Subaru OEM performance gauge pack's instructions specify the recommended torque.

Any idea where I can find the mysterious BSPT tap?

Found a 1/8" BSPT tap for $15.77 + S&H at McMaster-Carr. Part # 8328A11 at http://www.mcmaster.com/

Just ordered one, so I might eventually get to having my Defi EGT gauge operable.

I was trying to do this install over the weekend and could not get the old plug out of the block to install the new one. I have the right size hex key, but could not get it out. is there a trick to this? The engine had not cooled fully yet, would that make it a lot harder to remove?

Just ordered one. Thanks man. I can't believe I missed that site. Good luck with the install!

Do you mean you had trouble getting to it with the hex key or that you couldn't get enough force on it to budge it open?

I can get to it no problem with the hex key, but no luck in getting it to move. I can not find a way to get leverage on it. I was using the long end of the hex key to get down there, which left the short end for leverage which is not enough. I was trying to get the short end on the plug, but there did not seem to be room. I was running short of time and weather was rolling in, so I had to stop and put the intercooler back on so at least the car was running.

FWIW, I used a hex socket (with extensions) to get the old plug out.

IIRC my Defi was 1/8 NPT. I know the plug that is now in my manifold (removed EGT) is definately 1/8 NPT.

Ordered this thing yesterday and it showed up in front of my door TODAY! Thanks again Brentlz.

mbiker-the instructions that came with my gauges clearly say PT(BSPT). There is an option for an NPT sender but I don't believe I got this option. I've heard the NPT works with the PT but you might have leaking issues.

SouthSideTT-I've seen people insert the long end into the plug and use a wrench to grab the short end for leverage. I'm probably going to install this weekend so I'll let you know how it goes. Good luck.

Depending on which display units you have, the EGT gauge ships with either "1/8NPT" (for Imperial unit) or "1/8PT" (for SI unit) fittings.

sayonara: Hey, not fair! Knowing my luck, you got the last one in stock...I can also (always) pick the slowest line at the grocery store. <heh-heh>

Haha. No I ordered way after you so yours is probably on the way. I just happened to live in the next state over from where that company is.

Well I finally did the install this weekend and it went without a hitch and all is working well (only thing I don't like is that when the engine isn't running, the oil pressure alarm goes off and can get annoying when you need the power on but engine off). As for the oil plug you were having problems with, I rigged up a medium sized breaker bar (has a bending neck) to a long 12mm socket and inserted the short end of the 8mm hex head into the long socket. Without much effort, I felt it break and it was pretty uneventful after that. The crows foot wrench came in REALLY handy and I can't imagine doing that job without it. Let me know if you're still having problems.

I'd say it went pretty damn well Thanks again for your help...and lift. Now I gotta figure out how to rig up these mirrors so I can make them useful on a LHD car.
