Does anyone know what is involved with relocating the oil pressure sender on a 351C? In the stock configuration it is installed in a port at the top of the block near the bell housing and is very visible when viewing the engine compartment.

Some of the vendors sell a kit for relocating it. Is the kit needed, or can something be fabricated?

Thanks, Steve

The pick up point on the front of the block for the oil pressure sender is in-between the fuel pump and the oil filter. You need the hexed pipe that is in the vendor's kits if you want to use your stock sending unit. You will also need a plug for the old pickup point. The allen plug from the new point is too big.

They use the same hexed pipes in late model mustangs. I got mine off ebay.

Take it from a guy that did it himself, you are not saving anything trying to source the parts yourself.

In hindsight, I probably should have bought the kit. They were relatively inexpensive at the time but I don't know what they are selling for now.

It sounds like the kit primarily consists of a hollow adapter for the sender’s new location along with a plug for the original location of the sender. Is that correct? Thanks.

...here's what you need! Can be got at 'Home Depot' or any plumbing supply, but I always prefer BRASS fittings. Your sender mounts with a 1/4 NPT Male. The thread at the block, between the f. pump and oil filter is 3/8 NPT! SOOO You need: 1) 2-1/2" to 3" Brass tube with a Double 3/8" NPT Male ('double' means Both Ends). 2) One Brass Coupler that is 'Double' 3/8" NPT FEMALE. 3) One Reducer 1/4" NPT Female TO 3/8" NPT MALE. This screws into the coupler and Your sender into the 1/4" Female, the coupler onto the tube, and the other end of the tube into the Block! Hook-up the wire and Your gone! For those who don't know, NPT stands for 'National Pipe Tapered'! See the other thread about 'Oil Pressure Sender', right above! I Thank-You!...

Actually, all you need are two parts, one 3/8" nipple (don't get excited, that's a pipe nipple) and one 3/8" x 1/4" reducer (female x female).

...Clyde! Obviously You have never done this before! You will never mount the sender that close to the block because it Will NOT clear the oil filter. That is why You need the 3" Extension! You CAN, if you have relocated the Filter! "Know Your Song Well, Before You Start Singing!" Two More things: Some gauge manufacturers suggest NOT using Teflon Tape on the sender threads because it may interfere with proper 'Grounding', I use it and have had No problems as I feel the crest of the thread will cut throught the tape, and will ground anyway. Second: Mounting the sender at the Oil Filter/Block location, will read the 'Highest' Pressure coming directly off the Oil Pump! I prefer to have it located in it's original position at the rear of the block; reading the 'Lowest', 'Worked' pressure, this will more acurately show-up Problems with the oiling system as they first present themselves! Think about that!...

Actually you need these THREE pieces:

• one,1/4" NPT plug (this is a male threaded plug, as opposed to a female threaded cap), to fill your old sender location at the rear of the manifold

• one 3/8" NPT nipple about 3" long, to screw into the new location and get the pressure sender away from obstructions. A nipple is always male-threaded at both ends.

• one 3/8" FPT x 1/4" FPT reducer, to place on the end of the nipple and allow you to thread in the pressure sender. FPT = female pipe thread

Total of three pieces. You can buy these at Lowes, Home Depot, Ace, or, as I prefer, your old-time, independently-owned hardware store.

Like Marlin, I highly prefer brass for these items.

P.S. - NPT stands for National Pipe Thread

P.P.S. - Who the heck is 'Clyde'?

...Hey jb1490! I Had better learn MY song Better!! Beacause You Are Right! I forgot about those Double female reducers. Your Idea would be perfect with some 'Extension' for clearence. And Your design would have fewer 'joints' with a lesser possibility for a leak. Well Done!!...

...Thank-You Larry! Yes! You need the Plug to fill the remaining port in the rear of the block. I like the ones that are FLUSH and take an 'Allen' wench/key to install. You can even get them in Stainless Steel! And don't forget the Teflon Tape!...

Sorry, I forgot to mention the length of the 3/8" pipe nipple. 3" is a good length, as Marlin stated.
