It's something im interested in doing, I'll check out my local parts stores for the hose. I guess im questioning because I dont really feel a need to do the service at the moment but I have a feeling it'll be one of those "why didnt I do this sooner?" moments after.

This is quick cleaning so of course you will feel instant results but a good in tank fuel treatment like Gumout will do just as wellover a tank full of fuel. Trouble is within a few 100 miles the injectors are dirty again anyway...................the real trouble is LEAKING VALVE SEALS. If your injectors get dirty quickly then its time for valve seals.

i cant find the newer hoses part number. finding the can is easy but where do i get the hoses?
actually i cant find ANY of this stuff except one site that sells the cans in bulk for $400. i did find the hose adapters for around $130 for each piece. i was gonna bring the car and get this done professionally but if i can do this on the cheap for like $75ish then im all for it.
where are you guys finding this? even google searching the 3m part numbers are hard to find

you pull the fuel pump fuse so the fuel pump will not operate while the cleaning process is occurring.........the FI cleaner contains fuel to run the car at an idle speed as well as the concentrated cleaners.......when done with the cleaning replace the fuse so the pump will operate normally
That's very cool........

What?
How can oil getting by the valve seals have any affect on a fuel injector that's upstream of any oil?
Bad valve seals suck oil in from the valve covers and that oil gets ingested directly into the cylinder. That oil doesn't travel against the flow of high velocity air going into the head from the intake where the fuel injector does.
The cause of dirty injectors is a very old and deteriorating fuel filter........

Yea......That 3M method is certainly better than any in-tank additive because of dilution from the gas. That's why I use a full can of SeaFoam in just 1/8th tank of gas. But I do that regularly like every 3 months. I buy cans of SeaFoam pretty much every time I'm in the parts store just to have.
I wish that damn line wasn't so expensive......as well as the 3M stuff......I'd do the 3M cleaning. But as mentioned, injectors need to be cleaned all the time to really have clean injectors all the time. I figure 4 cans of SeaFoam per year is what I do to keep the entire fuel system clean......gas tank, fuel pump, all the lines and the injectors are cleaned.
But knowing me ill probably buy the line just to have it and ill do the 3M cleaning at some point. My girlfriend has a 2011 Vette too so we can both use it.

Nope, its not the fuel. Leaking valves(all leak some oil) ARE the cause of dirty fouled fuel injectors. Fuel injectors don't get dirty while you are driving. They get fouled with oil from the valve seals AFTER you shut the engine off HOT. The hot oil vapors collect on the injectors and cause carbon fouling and other nasty deposits.

Oh we'll, never heard of that. I had bad valve seals for over a year on my 427ci, like all of them. So bad that when we took the heads off some of the valve guides just fell out. It was a poorly done head job to begin with too.....never had a problem with my injectors.. But I guess I can see how vapors could rise up into the chambers.....
Fuel is a very powerful cleaner though.
