does my truck have blue spring mod

[jdb820]

dumb question here, can someone tell me how to check and see if my truck has already had the upgraded spring put in it? is the up graded one blue and the stock one not? like i said dumb question.

Correct old one is not blue. Just undo the side of the fuel filter canister ( top filter )

I was reading an article from Ford where they recomended to their techs when they do an upgrade to put a blue dot on the cover. It may or may not have one, only real way to tell as previeously stated is remove the cover and look at spring color.

Just thought I should mention it.

Why not just monitor fuel pressure?

Really the blue spring is a solution to not having enough FP in the regulator, if you are monitoring it, via monitor or gauge, and you've got the pressure you need. There is nothing to tear apart, unless you have a condition to correct.

Colo, I don't have the fuel pressure gauge for my dash boss yet. Going to get one very soon. I have no plans on gettin the blue spring until I get a gauge to see what my stock pressure is first. I agree with you, may not even need one. I was just wondering since my truck was bought used. I have noticed my 05 6.0 is not as peppy from a stop as my father n laws 05. His takes off strong and hard and mine is sluggish for a second. I have no problem cold starting, no jerking, or smoking so didn't think it's a injector problem. I am just wondering if after I get a fp gauge I will find low pressure could bet problem

If there was any proof weather the truck as it or not, you could have seen it on maintenance documents. My bet you wouldn't know, unless you tore it apart at this point.

Glad to see you are intending to monitor it.
