the_twig_187 Posted February 11, 2015 Share Posted February 11, 2015 I have never done this repair personally but have seen it done on youtube (diesel tech Ron). I have a truck in right now that has a fuel leak coming from the gasket on the supply tube plate and I was considering selling the "blue spring" fuel update at the same time because I will be in there already. was this a TSB back then? is there anything written about it by ford? a how to install manual in the box? does anyone have any words of advice or tips or trick on doing this? thanks always Chris Quote Link to comment Share on other sites More sharing options...
Alex Bruene Posted February 11, 2015 Share Posted February 11, 2015 If you order the fuel pressure regualtor seal kit (9T517?) it comes with the keyhole gasket, spring and plunger. No tricks necessary. Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted February 11, 2015 Share Posted February 11, 2015 No TSB or SSM but it's a known fact the regulator will boost fuel pressure at idle around 10-15 psi. The health of the HFCM will determine if its able to keep up with wot fuel consumption. I try to upsell the kit any time I am in one for injectors, coolers or any other major repair. I would definitely sell one for a keyhole gasket leaking Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted February 11, 2015 Share Posted February 11, 2015 There are different kits available depending on what engine an application you are working on. 6.0L F-Series, 6.0L Econoline, 4.5L LCF. The different kits contain different housing covers and minor hardware differences. All unnecessary.The only kit you need for any of these engines 6E7Z-9C165-B which contains the spring, regulator valve, seat insert, air bleed orifice, the o-rings and four bolts. You do not need to replace the cover unless of course you damaged it somehow. Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted February 12, 2015 Share Posted February 12, 2015 This is what I use in class and my book with a different PN, I wonder what the difference is- the casting? I bought this several years ago and it was an IH 1843065C98 rebagged. You can read the IH number through the packaging. It was pricey, like $80 IIRC.

Matt Saunoras Posted February 12, 2015 Share Posted February 12, 2015 Brad pointed out in a previous post on how to ID the new cover in the AG kit vs the original cover. There's a small difference in the way it's cast. Quote Link to comment Share on other sites More sharing options...
tonybullitt Posted February 12, 2015 Share Posted February 12, 2015 Do any of you guys remember removing the fuel pressure regulator and stretching the spring to get fuel pressure up. I had done it on alot of them before the blue spring kit came out. 1 Quote Link to comment Share on other sites More sharing options...
tonybullitt Posted February 12, 2015 Share Posted February 12, 2015 When the blue spring came out I had compared the blue spring to my stretched spring and it was the same length. Quote Link to comment Share on other sites More sharing options...
tonybullitt Posted February 12, 2015 Share Posted February 12, 2015 I started stretching fuel pressure springs after going to that 1 day classroom class. I think it was called 6.0 diesel roundtable. Do any of you remember that class? Quote Link to comment Share on other sites More sharing options...

the_twig_187 Posted February 12, 2015 Author Share Posted February 12, 2015 I always like to torque bolt that are sealing a fluid passage point especially. cant find any info in the WSM for a torque spec on the four T-27 plate bolts. it just says remove the bolt then at the end of the procedure it says "reverse the procedure to install" is there a torque spec? or just snug them and recheck for leaks when completed?

Bruce Amacker Posted February 12, 2015 Share Posted February 12, 2015 It's not unusual for torque specs to be missing in shop manuals, I see it regularly. There are generic torque charts for both metric and standard threads, I have them printed and hanging on the wall at the shop for times like this. I've also written the common lug nut torques on them. As for the length of the spring, it has little to do with the relief pressure. It's more to do with pressure than length. Stretching the spring will increase the pressure and therefore fuel pressure though. Quote Link to comment Share on other sites More sharing options...
the_twig_187 Posted February 12, 2015 Author Share Posted February 12, 2015 well I decided to just snug up the t-27 bolts with my 1/4 inch ratchet and no more leaks. the only thing I had a little trouble with was the cold side plastic CAC tube. no matter what I did I couldn't get the plastic tube off either the charge air cooler or the manifold elbow. I ended up removing the four 8mm bolts from the elbow and just positioning the upper half of the tube to the side so I had full access to the pressure regulator cover plate. other than that it was very simple and straight forward. thanks for the help guys Chris Quote Link to comment Share on other sites More sharing options...
Matt Saunoras Posted February 12, 2015 Share Posted February 12, 2015 That black plastic piece of crap is a pain in the ass. A heat gun will be your friend for the cac connection. As for the elbow I just leave it on and rotate it up off the fan stator. Quote Link to comment Share on other sites More sharing options...

You can even use a hand held propane torch 8 or 10 inches away from the opening to warm the plastic tube up. Quote Link to comment Share on other sites More sharing options...

Stretching the spring will increase the pressure and therefore fuel pressure though. Before the updated blue spring replacing the regulator spring would not gain any pressure with out stretching.Did you notice the blue spring is longer and a heavier spring?
