Replacing the vacuum line
Hello,
I have a 1993 f-150 5.0. It will miss when I'm accelerating around 40-45mph. It doesn't happen all the time but it has gotten more often. Since February the parts that have been replaced are: IAC valve, MAP sensor, distributor body, plugs and wires, fuel filter, and coil. Still, it misses. My next best guess is the vacuum hoses. However, while trying to price out what I would need I got totally confused and it seems that some pieces aren't even sold anymore. Has anyone done this and do you have advice for what I need to buy and what I don't need to replace? I'd like to replace all the vacuum line but does that mean I have to replace all the attachments? Help is very much appreciated.
Thanks,
Jedidiah

Forget about replacing it with the same plastic stuff. I did all mine with rubber vacuum line. I keep about 5 feet of each size. Measured twice and cut once.

Get roughly 24 ft of 4mm line, you will need to find two 3-way vacuum T's (or a single 4-way). Just like replacing plug wires, unhook old, run and cut new, move on to next hose.
These are silicone hoses and will outlast your truck for sure, 10X quality of the auto store rubber lines.

Hey so I finally got the money to buy what I need and I thought I was ready to purchase the vacuum hose but I just went out and measured one of nipples where the hose will attach and it looks like it was close to a quarter of an inch or 6mm. I'll trust you if you really think I need 4mm but I wanted to make sure before I bought a whole bunch of the wrong stuff.
