Ive got a blue fuel pressure spring kit here waiting to go on the truck. My plan was to install it today but I was wondering if I should be afraid to install it without knowing what my fuel pressure before and after was? As far as I know I have no fuel pressure concerns and I do plan on buying a isspro fuel pressure gauge but that's another $150 I cant put out right now.

 

I would still do it but you're really taking a pretty big risk not knowing what your benchmark pressure is right now...

Get the gauge asap.

 

Well I just got back from buying the M12X1.5 to 1/8NPT fitting and I also picked up a 2.5" 100 PSI gauge all for $15. My plan before I install the blue spring is to install the fitting and gauge into the housing. At least this way I can see my fuel pressure at a idle before I install the blue spring. I would really like to see the difference at WOT throttle before and after installing the blue spring but oh well. At least this way when I buy the isspro fuel pressure gauge I want i cant just remove the gauge from the housing and screw in the sending unit for the isspro gauge.

 

The only thread I've read where the press. was too high after the blue spring was when it was installed wrong.

I have the blue spring and never checked the fuel press but I also reringed the injectors at the same time

all you realy need to watch out for is fuel delution of the oil

 

The ford/international fuel pressure regulator update is not a performance upgrade, it is an OEM update, you do not need a fuel gauge to do the update.

 

F100... Would youmind telling me what you paid for the Blue Spring kit?
I just dropped by the dealer and they want $120 Cdn for the spring kit. I'm sure it was only $70-80 last year when I checked. Guess I should have gotten it then.

 

Try an International dealer with the no cover number. It should be around $30.

Fuel pressure regulator kit: 3C3Z-9T517-AG 1843065C98 or 1854267c94 (no cover)

 

Ford part # for the kit w/ no cover (should be much cheaper):
6E7Z-9C165-B

 

Thanks Guys,

I will give those #'s a try. But this is Canada and most likely the dealer cant or wont get those parts.
3C3Z-9T517-AG is the one they want $120 for.
Heading into town today. See what I come up with.

 

Can you mail order it?

www.partsguyed.com is a good place. But I don't know, you might pay more in customs than you save in the price of the part.

 

Not only is the customs bill sickening they hold stuff for a month most of the time.

 

All you guys from Canada I paid $27 at the local international dealer for the kit. I used part number 1854267C94.....there's two ford part numbers floating around on the forum for the kit with the housing and without the housing...out of curiosity I checked the price at ford and the guy at the counter couldnt do anything with either part number. He said they are both USA numbers and a none stocking item. He then asked for a year and make and said he would try to find what I was looking for. He found the kit without the housing for around $90...I asked for the part number but he only gave me the first 4 digits and I could tell he didnt want to give me the whole number. So i just said no thanks and went to international. International here in BC didnt have it in stock and it took 2 days to bring one in from Alberta.

 

Tagged so I can find this tomorrow.

Thanks,

 

Is there a guide in the tech folder for changing the spring? I've looked all over and haven't found it yet but that could be a good thing meaning there is so much info in there to use
