I want to hear from people that have actually had problems with o-ring failures with the injectors after installing this spring. I know it gives 100psi, just want to see if anyone has had actual problems?????
How long have you had yours in? I had my GDS spring in for probably 2,500 miles and I installed a fuel pressure gauge and it was at 100psi at idle. Put the stock on in and at wot I'm at 40. So I am right in the middle. I know what the injectors are rated for and was wondering if anyone has had actual problems with high psi or what? ThanksI'm using the GDS spring...to my knowledge it's working fine.
I believe my fuel pressure is high like yours, but I haven't measured it. I've got a pressure gauge....just haven't gotten the time to do it.
I have heard that too. I was wondering if everybody was just hearing this or if there are actually people out there that have had failing o-rings from the pressure being over 75psi???i have always been told that the stock injectors o rings will start to fail with fuel pressure over 75psi but dont know for sure i just used the ford spring and mine is around 70
45 psig is the minimum spec based on the need to cushion the piston movement - because of its speed it has quite a bit of inertia. That is from Ford. I don't believe that they would design a minimum mechanical spec that did not fill the injector (and therefore not meet the combustion needs). You can ask for proof and I can not give it to you on this one. It is just sound mechanical engineering and I am assuming that it was done correctly. There is certainly a minimum time span to fill the injector based on a minimum pressure, but 45 psig isn't it I don;t believe. For me my experience is enough to satisfy my curiosity on these specs ..... I have run WOT at 45 psig (before my spring upgrade) and there was simply no "injector missing".I like to learn so even if there is no difference between the 45 or 75 PSI going to the injector you can't tell me that there is no difference in the time it would take to fill the injector.
Sooo, do you have one in your fuel regulator or? I guess you should of sold them yourself because they have sold over 5,000 of them.I didnt realize these spring were for the 6.0 when I made them for Gillette Diesel. I make all of there springs for them. Whoops. They make a hell of a profit off these spring since I make the for like 10 cents a piece.
