I'm getting ready to install a new fuel plate on my truck, and have a few questions.

My truck has the plastic AFC boost line and I'd like replace it with a metal line. Has anybody done this, and what did you use? Soft copper and brass compression fittings might look hokey, but it would sure work nice. What size fittings are necessary?

What's the deal with the break off screw? Why install a new one? Can't you just replace the screw with a standard screw?

I'm not sure about the line but the screws I just socket head cap screws. You only need to use the break off screws if you want to make it look untampered with.

 

I usually replace all four screws with allan heads after opening the AFC for the first time.
Guess if you want an all steel line just buy one for a '98.
The older style plastic one has worked fine for me the last 200k

 

Are you using standard or button cap screws? What size and length thread?

The idea behind the metal line is that the chances of it leaking are minute. I'd be afraid of cracking the plastic line, but if it hasn't been a problem for you infidel, I guess it shouldn't be a problem for me.

 

Standard top, sorry on the sizes, I took them down to my local has everything hardware store and bought a handful long ago without even looking at the sizes.
Do know there are two different lengths though.
If you want to make it a true one tool job also replace the bolt down below that holds the lower shutdown solenoid bracket. This bolt has to be loosened in order to swing the solenoid bracket out of the way.

 

Here are the sizes, based on info I have written down.
Get yourself Socket head cap screws. Got mine at the local hardware. Top ones are M6 x 16mm, (18mm will work). Bottom ones are M6 x 25mm long. Torque plate bolts are M6 x 12mm long.
