Engine/Transmission (1998.5 - 2002) Helping Installing Guage Senders

Help Installing Gauge Senders

Well I set out today to install the gauges I bought a while back, and it didn't go as planned. The guages I have are

BD Low Fuel PSI dummy light

Banks Boost

Banks Pyro

Banks Trans Temp.



I have questions with all of them. I have to say the instructions are quite vague and I'd rather not just guess.



On the fuel pressure sender...

The instructions say there is a test port on the supply line banjo bolt for 98-00 trucks. Well there isn't one on my truck that I could find. I have the banjo bolt fitting from BD for the newer trucks that's supposed to go where the shrader valve is. Now this banjo bolt fits on the line of the VP44 that's to the back of the truck (supply right?). Is the proper way to install??



This is the forward banjo, I though it had a fitting on it, but it looks like a ball bearing plugging the hole. ?

The right hand one is the one that the BD fitting can fit onto.

BD fitting and sender. Stock fitting.

With the boost guage, I was told on another post on here, they best place to put the sender is in a 3/4" plug that's back from the fuel filter. I found that plug, and also there is a smaller plug at the end of the manifold, 1/2 I think? Does it matter which I use? I tried removing the larger one and I couldn't get it loose. Are they normally pretty tight?

The pyro, is there a specific place on the manifold it should go? I looked at a few setups and they were right next to the turbo flange on the back side tube. On that tube, is there a specific place I need to put it? I read something about a divider being in the manifold?



And the trans temp. The instructions say to install the sender in the rear servo test port, which is in the right rear of the transmission. Seems simple enough... though there are 4 ports on the right of the transmission!. I'm guessing it's the one that's lower and far back, but I wanted to make sure.

On top of your fuel filter there two small plugs,the one closest to the center is the outlet side of the filter,the other is the inlet pressure. The engine vibration will kill the sender in a short period of time. I used a grease gun hose to attach to the filter housing,then the sender on the hose. There is a photo in my gallery. You may need a double female fitting from hardware or auto parts store.

Do you have a Service Manual? That is the first step I would take. Then -

I have a 02 and use the plug on the intake manifold. But you have to use the correct one, ie only one is manifold pressure, ie SM.



There are a lot of TDR threads about drilling and taping the manifold and exactely where to drill and tap.



I replaced my 02 transmission hot line with the '95 transmission hot line to get the port to get my transmission temps. I think that using the ports on the transmission are not good ideas because the oil flow is not in all gears and not right to give a good transmission temp in all gears. I am pretty sure you need to get into the transmission cooler lines. Either the port in the '95 line or into your own transmission cooler lines.

On the transmission temp sender,I used a Mopar oil cooler tube #05011244AA. This line is for a 95 year I think. This is the line that goes from the drivers side,front of transmission to the small tank that is under your turbo. This line is a direct replacement,and has a port for your seader. If you use this line ,you should remove the small check valve from the tank end of the line. This line is not cheap 80. 00 to 100. 00 dollars,but it's the safest way. This location gives you temps from your converter,the hottest in your transmission.

On my 01. 5 I cut the output line from the transmission to the heat exchanger at the 90* bend on the side of the engine just below the turbo... the last bend before the heat exchanger. I used a pair of 1/2 inch compression fittings going into a 1/2NPT "T" fitting. The "T" replaces the 90* bend and leaves one port toward the front of the motor. I bought a reducer bushing and installed my temp sender for the transmission there. Has been working fine for a couple of years now. This location will give you a better idea of your transmission temps than any plug in the transmission case.



The right side of the two fittings on the VP in your picture is the inlet into the VP. That is where to install the adapter fitting you have. However, do not mount the sender directly on the motor... it won't last. A good quality grease gun hose makes a good extension. I used fuel line fittings and a couple of feet of 50 lb burst strength fuel line on mine. Even a modified fuel system will only hit around 30 and a stock system only 18 top. I think that is a safe margin.



The big fitting on the back of the head is the best one for the boost gauge. If I remember right, there is water behind the smaller one. I had no trouble getting the big fitting out of my truck. If you can't get the fitting out, I would remove the air horn that is just above the heat grid on the intake and drill and tap it. If you use the large fitting on the side of the head, make sure your new fittings do not go into the manifold far enough to affect the air flow past them. I understand that area of the head is kind of restrictive anyway and you don't want to make it worse!



Your discription of where to mount the pyro is good. I found information on here recommending an exact location. You might try a search. It is about in the center of the rear port and an inch from the flange.



Hope our information helps.

For your pyro look here. http://www.tstproducts.com/pdffiles/instpy25b.pdf

The plug all the way in the rear is the water jacket, use the one closest to the filter, it's right next to the map sensor, you will need several step-down adapters depending on the gauge, on my Autometer it has small plastic hose like most oil pressure gauges. You can put the pyro sender on either the #3 or #4 side of the manifold right before the turbo flange, there is a divider in the middle, don't drill there!!! Dunno on the transmission

Thanks for the help!



I have the reducers for the boost sender. It's just I wanted to make 100% sure I was trying to remove the correct plug before I messed anything up. I'm sure it will come off with a breaker bar and some force.



I'm going to pull the turbo off to drill for the pyro. I was going to drill it with a magnet near by and use grease, but I was told that's it's pretty easy to remove the turbo, and that I shouldn't risk it.



I got a grease gun hose for the fuel pressure sender. I was told to run the modified banjo fitting on the exit line of the filter housing instead of on the pump. I don't know if it really makes a difference?



Sounds good for the transmission. I did the same thing to my Jeep. I was thinking Banks instructions to put it in the transmission would give me a more accurate reading. Which line is the one carrying hot ATF to the heat exhanger?

The line coming out of the front of the trans is the hot line... the one on the rear is the return.
