Fuel Injectors Replacement
Got a question ... I purchased gas somewhere with rust sediment in in.
As a result it went thru the filter and into the injectors, started missing
bad and gave a code 3040 ( missing on cyc.#4 ) I flushed the tank,
fuel lines and replaced filter. I would like to replace the injectors but as
yet have never had the honors of doing so. The question is - is there any
clips or keepers that hold the injector in place...or does the fuel rail only
do this?

Thanks for you replies. Have any of you guys replaced an injector?
Are the injectors held in place by the fuel rail? Are there clips also?
I can't seem to find an illustration of ford (3.0) injector replacement.

You don't say what year your truck is, but looking at the Haynes it doesn't look too difficult for a 3.slow. If you'll give me the year and it falls in the years my Haynes covers I'll type the directions up.

The reason I withheld that information is because my fuel problem is on
my '01 Taurus 3.0 Vulcan engine. I also have a '02 Mazda B3000 that is
virtually the same engine and parts. I have crossed the injector part #s
and they are the same. So information on either one would be great!
I just hope ford don't drop out the Vulcan 3.0 engine in the future.
Thanks,
Tom

The only thing holding the injectors into a Vulcan is the rubber O-ring at the tip, and the fuel rail. If you remove the old ones, the 'hats' will probably break. They get brittle as they age. You *can* replace just the hats if you want, but you have to find the right part number.
If your filters were working, you should have no rust sediment in the injectors. There is a sock on the fuel pump pickup, and the replaceable filter should have taken all the rust particles out. I'd be checking other things before the injectors.

The fuel filter was a motorcraft about a year old. I have good reason to
believe the contaminated gas from a refill at a local station. I'm going to drop the tank & flush it out...I see no other choice at this point......for sure the
filter didn't do it's job!! I see "airplane " hose clamps on the fill hose to gas
tank.....would be my luck the sock isn't on the fuel pump. I purchased
this car when it was 1 year old. Thanks for the great information and any
thing else you can think of would be most appreciated.

If you are going to drop the tank and pull the fool pump, be very carful with the fuel line. They also get very brittle with age. And, feature attraction, Ford will NOT sell you the approx 3 foot section from the fuel pump to the filter... at least they didn't. It is hard to justify a $300+ part (from tank to fuel regulator) to get a 3 ft section.

Also, when you say dirty fuel, is it particles or color? There is a guy in Indiana (Indianapolis?) that will clean, inspect, calibrate and test injectors. Speedway, maybe, near the track. THere is also a very small sock in the intake side of some injectors.. (belt, suspenders and... ) that is the last resort filter. It may be possible to remove the injectors, clean this last little sock, and replace them.

I didn't take the tank completely out, I flushed out thru the filler opening in tank.
The frustrating part of this whole deal is that the rust is so "microscopic" that it
passes thru the filter to the injectors. I am in the HVAC business and use a 6
cfm vacuum pump on the fuel rail to pull the rust out of the injectors.....probably the sock
you were talking about(in top of injector). I can then take it out on the road and
it runs like new.........but within 40 miles the rust is there again......3 new fuel filters so
far and it has passed thru them all.( 2- motorcraft , 1- Purolator ) If someone made a
very low micron filter this stuff could trapped there. How could that information be gotten?
