Hello and Welcome to Justanswer,

My name is XXXXX XXXXX I am here to try and assist your with your question.

Do you know the calibration number, its on a small white sticker on the driver door or the cab.

Expert:  Ron replied 5 years ago.

Are you sure of this number. That isnt a valid number for the 1988


Here is what I have listed.


Customer: replied 5 years ago.

That is what it says. 8-76A-R10

The VIN is 1FTHF26H4JPB01917

There is also a smaller number that is E-8AE-6E061-Fordage

Expert:  Ron replied 5 years ago.
This one should be the correct one.

Customer: replied 5 years ago.
That looks way too simple. There is a group of 4 colored lines that go over where the CPRV thing is on the passenger side of the engine and a shaped hose with two 90 degree bends in it that have been cut by the previous owner. I can try to use this diagram but I think this truck has a whole bunch more hoses than this picture.
Expert:  Ron replied 5 years ago.

This is all They list.
Customer: replied 5 years ago.
I will go out and see if I can match this to what is under the hood. IfI can I will come back and accept the answer

Ok, let me know.

How do I get a refund? Before I paid it said I could get a refund if the answer did not help me. It did not help me and my only choice is to ask another question. I do not have another question. I think the website lied to me about the refund. Is this website based in the United States?
