What's INTERNATIONAL list for the spec?

 

thankyou for all the feed back i think im just going to order a new spring from gillette diesel

 

OK, you guys got my attention. Since I ALREADY HAD a FUEL PRESSURE GAUGE INSTALLED I thought I would try the "BB" and verify the results.

My 2003 6.0 fuel pressure was running below what I thought was acceptable. Measured via the IDP adaptor line with a liquid filled 'permenantly installed' under hood gauge I was running about 48 PSIG at idle and 45 PSIG at WOT (in park).

I installed the BB and the results are as follows:
65 PSIG at idle
63 PSIG at WOT
I am very happy with the BB Mod. I can't say every truck will get the same results but it worked for me. I didnt stretch the spring and couldn't see paying $20 to Gillete for a spring.

So the conclusion is after 118K miles on my 03 "IT WORKED"

 

What's the International spec for fuel pressure?

 

Please don't consider me an expert, I get all my intell from these forums but everything I READ says International spec. is 70 PSIG. Ford spec is 55 PSIG "I Think".

 

Off the top of my head it's in the neighborhood of 70, I can't remember now and all my manuals are at work.

I try an make it a habit of not memorizing things I can look up - everytime you learn something new it pushes some old stuff out of your brain!

 

Yep..I'm pushing out tons of stuff. Thanks for the info. If you get around to digging it out it would be much appreciated.

 

nevermind

 

It's not like the injectors are going to run out of fuel at 55psi. It's that the pump can't always supply 55psi and it drops. 55 is fine as long as you can keep it constant. Shimming seems like a waste of time to me.

 

What is the BB mod?? does it cause any problems?? and what do you gain from it?
