Which one do I have???

This may sound like a stupid question, but I want to order a fuel injection performance kit for my 1995 F150 with the 4.9l in it. When I am looking for it, it shows two different ones to pick from, stating that one is for if you have mass air flow and the other is w/o mass air flow. How do I know which one I have???
Any help would be greatly appreciated...

I called my local parts store to see if I needed a Mass air flow sensor for my emmisions problem and they looked it up to find that I did not have one on this truck. Hope this helps, gr

OK. What is a "fuel injection performance kit" and what makes you think you need it? If this is a "cold air intake" then stop now, because your truck already has a cold air intake, and adding this kit will remove the "cold air" part from your intake function.

The mass air sensor should be mounted between the air box and the throttle body. Mine has a single large tube coming off the air box and then splits to two hoses.

To tell if you have a mass airflow system or not you open up the hood, put the rod in place so that the hood will stay open without you having to hold it open then look for a mass airflow sensor. If there is no mass airflow sensor then don't get the kit for that calls for "mass air flow".

Simple as that...

If you don't know what you have and don't know how to figure out what you have, performing any sort of modification sounds like a bad idea.

I believe you do have mass air but first check under the hood. There should be a silver sensor between the air box and intake tube. Thats ur mass air sensor. If there isnt one, then you dont have mass air.
