Oil Change

Normally, you need this extension for the sender to screw into.

Question about that extension... I was looking in my NPD catalog and there's 2 kinds.

65-66 - 289, w/gauges, steel, 4.3" long extension, works on 67-73 as well

67-73 - 289, 302, 351

The sending unit you sent me is for a 66.. but I have a 302. Which extenstion should I get? Is the one for 302 going to fit the 66 sending unit I have?

A 289 and a 302 are pretty much identical on the outside of the block. I'd think the one for a '66 would work but if nothing else one way to find out is give it a try.
 
The way it works is that oil will go to the sending unit via the passage in the extension and then the psi will be converted into an electric current and sent to the gauge. So, really as long as you get the oil from your engine to the sender under pressure the gauge will register.

So get the 66 extension and give it a whirl. You can't hurt anything.

Kat,
I believe I have an extra oil sending unit extension if you want it. If you do, PM me.

Both Shag and Red are running NAPA's Gold 1515 filter. Brad Penn 20/50 in Shag and their 15/40 in Red.
 
I called NPD to ask them, and the guy said try the 67-73 one for 302. Something about the size of threads on the 302 block blah blah blah.
 
Kat I have a 302 as well and I just got an extension from NPD, it was part number 9B339-1 and was $24.95. Fit perfectly

Hope this helps.

That guy's on crack. The threads are the same. I'm running my original 289 extension tube on an '89 302 with no issues.
 
Shag's original oil extension is on it's way to Texas to mate up with Gertrude. :eek

And no Kat, I'm not going to clean it. So be sure to clean out the insides real well. You never know where that extension has been.

:lol

Now that's just not right.

Kat, you can go to any parts store and get some nitrile gloves and a can of brake cleaner. Put on the nitrile gloves before you open any packages coming from the NorCal area, then use the brake cleaner and spray the part down liberally. Use the little red straw to clean out the inside too.

You will need to suck on that straw real hard for the amount of built up crud will be a challenge :lol
