Help me I'm stuck! I'm trying to install the ITP in-tank mod and the instructions tell me to bleed the fuel system pressure through a schrader valve. I have an '03 and thought I didn't have the schrader. The shop manual does not give a good enough description of it's location for me to find. I do have it does anybody know where it's at or if I really need to bleed the pressure down to disconnect my fuel tank lines? I'm stuck until I can figure this out. Do I really need to bleed the pressure?

 

They are probably talking about a pre-1999 old body style with the mechanical fuel pump. They have a schreader valve.

 

If I'm not wrong, you can relieve fuel system pressure by just opening the drain on the back of the fuel filter, assuming you still have the stock fuel filter.

 

her is the directions you should be useing

when its all put together..fill the ITP filter with fuel. before you put it on..just like you should with the oil filter..only with oil..lol.cycle the key 2 or 3 times..then fire her up...it will take a few miles to hear a diff...

 

That's what I thought too, except my 2003 shop manual is telling me different. I'm going to drain the bowl and run with it.
I am using them. I even printed out a color copy (ITP sent me black and white) so I could see better. The tank removal instruction are just a copy out of the Ford service manual, which is what I have. It tells me to bleed pressure and refers to a section in the service manual that tells me to do it via the schraeder valve.

I'll go with draining the bowl and let you know how it goes.

Thanks everybody for the quick replies! I may make it home before dinner!

 

Let us know if you need help. I'm just watching my Colts beat your Chargers... hopefully

 

Oops......

 

NOT... Now it's time to watch the Cowboys whup some @$$. ( KNOCKING ON WOOD!! )

 

Let me know if you need help for sure, I've got nothing to do until next season! Congrats and yes my foot tastes good!

 

Thanks for all the support. Sorry about the Cowboys (okay, maybe not so much) and I was rooting for the Colts. The Chargers don't have a chance against the Patriots and I want to see them lose (I'm a Dolphins fan)!

I drained the bowl just to be on the safe side even though I was working from the tank to the fuel pump suction. I assumed it helped since no fuel went spraying during the install.

The mod is great! Fitment, parts quality and quantity were spot on. The engine is quieter now. I used to hear the rattle everywhere up front but now it's only coming from the bottom. The injectors don't sound nearly as angry now. I loved being the loudes engine in the parking lot, but if it will help my injectors last a little longer then the sacrifice will be worth it.

The only problem I ran into was that nothing had been disconnected in 5 1/2 years and 154K miles so saying that all the fittings were stubborn to remove would be a huge understatement! Also I don't know what Ford was thinking by putting a locking fuel fitting to the suction of the fuel pump. There is no room to put a line release tool in there to pop it off, you have to buy a new pump! So to facilitate the new fuel line I just carved off the old fuel line and double clamped the new line on. Other than that and my truck being stubborn (install took 9 hours total) everything went perfectly!

Even though I don't notice any SOTP improvement I did notice that getting onto the freeway now (merging into traffic in Southern California can be tricky with over 20ft of truck) I leave a larger black cloud on the on-ramp than I remember.

 

Hey Brian, There is a little hint about the fuel pump fitting (tank side) twist the fitting, and remove the little clip with pair of needle nose pliers, and it comes right off. you do have to loosen the FP bracket a to give you a little wiggle room.


Glad you got it done, You will like the benefits more and more as time goes on.

 

I was thinking about doing that. I was going to use a pair of dikes (that's diagonal pliers for those of you with dirty minds), clip that ring and remove the fitting. The only problem is that I told my wife I was going to be done by 3pm and I didn't even run into this problem until after 5 pm. Knowing that a storm was brewing in the house with the wife, and the fact the sun was going down and light was getting scarce, I went with what I thought would be the quickest and safest solution. If I would have started to remove the connection and failed (but had damaged it beyond use), I would either be there even longer or not be able to come to work this morning. Both of those options were bad ideas. So I knew I could cut the old line off and push the new line on. Since I was supposed to double clamp it to the pump intake I just double clamped it to the fitting on the intake.

Next is an extra tranny cooler, cackle cure and headlight harness upgrade. My 4R100 hasn't been rebuilt yet (154K) and, knock on wood, still has some life left in it. I was reading that a 10F drop in tranny operating temperature doubles the fluid life.

 

Brandon -

I am going to be doing an in tank mod this week. Is this the type of fitting you were talking about?

 

that would be the one..

 

Thanks Brandon
