installed cali spec fpr spring.

trying to help smooth out my idle, so decided to go ahead a buy the fpr repair kit for a cali spec 7.3. the cali trucks use different injectors, and therefor ford bumped up the fuel pressure a little bit for them. my stock pressure measured 60 psi. after swapping springs, its dead on 80 psi. didnt want to go the bb route and over pressurize anything by accident, and at least this is within ford spec. seems to have helped. the top spring in the pic is the new cali one. seems to be wound a bit tighter and more stiff.

i've heard that doing a high preasure cross over line between the heads also helps smooth out the idle just a thought for you

thanks - i actually will be doing this, but using a different method. instead of buying a cross over line, you can accomplish the same exact thing just by removing the valving springs on the HPOP.

I have more than enough going on with this truck right now so one of these days ill get around to it. the FPR spring took 5 min so thats why i got it. anyway, if you get the HPOP oring kit from dieselorings, or somewhere else - replace orings as usual, and just remove valve springs. this will allow the pressure in both lines to now balance in the pump, intead of buying a cross over line. thanks for the response though.

From ford.. fpr repair kit.. the part number is floating around, my laptop just crashed or id post it. Its not cheap though. Brass plug, spring, and that piece inside the plug came in the package - $48 total , but at least its not putting more pressure on an already worn out spring...
