Hello, in my land there is a saying or saying that says:
Eating and scratching is all starting.

Here we would have to say: I can't stop filing (with the file, I don't know if it translates well)

I have finished the LIM but I do not finish filing the UIM, it is endless.

To rest from filing I entertain myself with the wiring ...

Hello, thanks for the encouragement.
On the one hand I like to work on the car slowly but on the other hand I would like to have it and be able to use it now ...

A question,
Are the hoses going to the injection rail normal? do they have any special characteristics? Or can I change them for a standard one?

Thanks

Well, I answered myself, I bought an 8mm gas tube to replace it

Another question, the MAF of the f-150 4.2l
F81F-12B579-BA

I understand that electrically it has to be valid?

If you change the MAF you will need to tune the ECU to work with it.

For what it's worth, most of us with 3.0 swaps are still using the original 2.5 MAF sensor; it's not a known problem.

Hello, well then I will park the issue of the MAF and improve the admission, which for now I have 2 and they work well for me.

Another thing:
Ford Windscreen Washer Valve 6747269
I think I have them both wrong and I can't find the original
Can they be repaired?
Do I have to change them for a standard non-return valve?

I have cleaned them and blow on both sides and no air comes out, is that normal?
Thank you

On occasion I have used a needle to clear out the washer nozzles.

Hello one question:

I have bought a repair kit for injectors since the rubber rings are very bad and incidentally change the filters.

But the game brings a hat that is put in the mouth of the injector smaller than the original

Does this smaller size matter or will it give more heat to the rubber and is the new one worse?

That's not right. You need to find the correct O-rings. That kind of mistake can burn your car down.

Measure them.

The new rubber O-rings are pretty much always SMALLER than the ones you take off, because they grow and stretch with age.

Hello I am concerned about the issue because it is the first time I touch an injector ...

I have seen in:

A note that says:
Inside: 0.296in = 7.5mm
Exterior:
0.574 = 14.5mm

The injector has a diameter:
7.79mm

My rings have
inside:
7.89mm difficult to measure
Exterior
14.46mm

I have mounted it and although it does not have any holes and does not turn freely, it does turn with little force and I do not know if it is the right thing to do.

How hard is it?

The ones that I have removed were the last rubber and they split so they are not worth measuring

That sounds like a good fit.
The measurements are probably within a reasonable tolerance for a rubber O-ring.

Anytime you open the fuel system, the next time you start the car make sure to take the key to "On" first and check thoroughly for leaks before starting. Then continue to look for leaks after starting until you're confident that everything is tight.
