I'm looking for a stock extension part that the oil pressure sender attaches to. I used brass fittings which have been leaking. The junkyards around here close before I get out of work, and I haven't been able to get to one on a Saturday morning.

I called the local Ford dealer, and the counter person said they don't sell it. If anyone has a part # that would help, as this person didn't want to help me too much.

Thanks all.

Steve,
I found that the stock extention was a little to long. It made the sending unit hit the headers.
I used a steel Weatherhead fitting #c3359x4 which is a 1/4"MNPT x FNPT 45 deg street elbow. I ended up adding a small extension to this fitting so it placed the sending unit in a location that I could get to it if I needed. The extension part is Weatherhead #c3209x4x4. Both these fittings are plated steel that I got at an industrial hose supply house. But if you would like I can send you my old stock extension.

Nearly all of the Mustang supply stores cvarry them, and they are pretty cheap. That's the problem - they are cheap. They are made from cast aluminum and I've managed to break a few over the years.

Use a pair of NPT-AN fittings and a short piece of -6 hose. Then you can mount the sender anywhere you want. If you mount it pointing down, the oil won't drain out while sitting, and you'll get an instant reading.

Thanks Dan. I have to go get a couple of hoses made for my boat trim tab, so I will take the part #'s with me and see if they have them. I will take the stock fitting though. It's the only leak I have on the entire engine and it's driving me crazy.

Steve,
E-mail me your address and I'll drop it in the mail/UPS tonight for you.

Thanks Dan, you've got mail.

Bob, if you used a piece of AN -6 hose, wouldn't the sender be flapping around? I would think you would want it in a fixed position.

Of course, you have to secure it to something. You don't want anything banging around loose under there. A simple $.50 padded hose clamp fits very nicely. And you can attach it to any convenient spot - head, oil pan, frame rail, crossmember, fender panel, etc. It works well, provides a tremendous amount of flexibility, and looks trick.
Of course, if you have a remote filter mount, you can always mount your pressure sender in an AN fitting at the block input point and use the pressure hole for a temp sender. That lets you know the pressure and temp of the oil being fed into your engine, after the filter and cooler.
Just pointing out some options.

You don't have a picture you could post do you?

 

[Bob Cowan]

No, don't have any pictures. I sold the last car I did that to. Eventually, I'll be using the same type of set up on this car.

But it's actually pretty straight forward. You are simply replacing the cast alum tube with a flexible tube.
