Does tis OTC fuel injection kit come with the Application Manual 6550MAN-13?

Mine did, it tells you which adapters to use also. Nice tool, just need to buy the adapters and they seem to only come in a set.

I have a 1988 F150, would it work on it ?

This item works with all vehicles, if you purchase the right adapter

How effective is this tool on a v6 engine?

This tool doesn't care if it is a V6 or a V8. It's job is to deliver cleaner to the injectors. With the right cleaner, it will do a superb job.

Are there any retail outlets and sell the OTC chemicals? I don't want to pay the high shipping costs.

Hi,Just so you know on amazon the shipping costs are irrelavant they are simply the cost of the product some sellers are offering this particular product with free shipping cost example amazon $133.77 with free shipping another seller offer $119.99+$10.90 shipping almost the same the shipping cost is part of the price just depends on how the seller decides to make the offering just wanted you to know. To answer your question OTC is not really a product any retail store carries I honestly can't name one retail store that carry the OTC brand.Thanks
