I have finally gotten my old npi manifold off of my 1997 T-bird. My existing coolant tube runs down the middle then turns to the passenger side head as it exits. The Mustang websites seem to say their tube turns to the driver's side head. Does that mean that the pi coolant tube cannot be used without a modification? Will I be cutting it off near the firewall in order to re-attach driver side tube with the passenger side? I'm also thinking of leaving my stock pump nipple as-is and running some curved or pre-bent coolant hose to a suitable cut point on the pi tube.What is the best hose to use if a brand or type can be specified? Also, are Felpro and Victor Reinz pi gaskets as good as Ford's? My local Ford dealer wants over $50 a set, so it will most likely be one of the other two at half the cost. How is the wiring harness gotten out of the way? I moved it around to get the manifold off, but it would be best to really get it out of the way completely when I put it all back together. Also, if the injector o-rings come out round bodied instead of compressed, could they be re-used? Tell me what has worked for you guys, and what hasn't! thanks for facts , edman

the pi intke gasket get it from jason here at fordpartscounter in the forum for about 20 or 30 bucks shipped.

if using rubber hose you'll run the risk of the hose start hardened up over time and it become brittle. i'll get a pic for you in a day or 2 on how mine is set up. basically cut up the stock tube and and the pi tube and connect it with a short heater tube hose and clamp it.

the wiring harness you just need to lift it up couple inch and the intake can be slide off from side.

injector oring can be reuse if not compressed. just make sure no rip or tear and lube it up with some engine oil before reinstalling.

the proper way is to take off the water pump and tap the old nipple out and insert the PI coolant tube nipple, followed by the PI coolant tube which goes up and toward the drivers side to clear the PI intake, it than runs along the head than down and left, and than up and toward the passenger side head with the same connection point as your current tube....

the problem with this is that it doesn't have a bung for the heater sensor for auto climate control equiped birds.....

some people bend the stock hard line to work (most people crack it while attempting to bend it)
some people run the PI tube and relocate the sensor with a T fitting
some run solid rubber heater hose with a union to the heater core and the stock NPI nipple
some run hybrid stock and PI tubes (I've heard many combos with this one)
.....stock nipple/plastic heater hose 90* fitting hammered on with a splice of hose than the PI tube than the npi tube
.....PI nipple, PI tube cut and flared behind the passenger side head spliced to the NPI tube with heater hose
.....PI nipple, PI tube with the sensor cut off of the NPI tube and brazed to the PI tube
.....people get really innovative with these things..... find what works for you....

Good information. I was just about to start a thread about this when I read this post. Does anyone have more information on this option?

I did the PI coolant tube, rubber hose from driver side to passenger side, a TEE with the sensor for my semi auto temp control, and the original heater hose to the top of the TEE since it is exactly where the other coolant tube would be.

If you don't have SATC, then an ELL would work well in place of the TEE.

anyone at a reputable shop with some TIG skills should be able to braze what you need.... pressure test to at least 20lbs

Total cost involved pi swap.

I went to my local Ford dealer's parts counter and , the coolant tube was $93, the nipple was $10, and the two o-rings were $13 a piece! I guess I will have to buy mail order after all! And it looks like I will be driving my Chevy back-up car a lot longer than I planned! So for all you guys that know where the best deals are, I want to know ( suddenly )!!

all my parts and everything cost a total of 270 bucks. I just cut the new coolant line, and added in a silicone hose( hoses that are on the police cars) as the bend. Took a couple tries test fitting it, but it fits like a glove. For the rear hose I got a 90 deg bend, and some heater hose and connected it. 5k miles and no problems.

Anyone have a picture of how the tube connects to the back of the engine. A before and after with the stock tube and the PI one would be helpful.

Ok I finally came to the realization tonight of how the stock tube connects to the rest of the cooling system . It wasn't clear to me from the pictures I've seen. I didn't understand that you could even see the connection with the intake still on the car.
