oh ok cool thanks. So I have to ask for a brake line and not a fuel line? About the carb, what else do I need? Will I need new gaskets or will they come with the carb? What about installing it? I took the old carb off the engine and was able to put it back on, also put the linkage back together. is it just like that for the new carb or is there something else involved?
Yes, ask for a steel brake line. They will probably take you back behind the counter to a rack full of diffrent size brake lines. You want one that is 3/8ths in diameter and about 3 foot long. Once you get it installed on the car, you can cut the excess length off. If you have already removed your carb and put it back on once, installing a new carb is the exact same process. Remove 2 nuts, fuel line, throttle linkage and a vaccume line. I can swap a carb in like 10 minutes.
If you've removed/reinstalled the old carb, you shouldn't have a problem with putting on a new carb. The hardest part in installing would pretty much be readjusting the carb, which isn't too hard either if you read up on it beforehand. Any questions just come here, there's tons of people who can help you out.
Right Stuff Detailing shows a pre bent line. The Maverick stuff is at the end of the Mustang section http://www.rightstuffdetailing.com/2004_pdf/mustang.pdf But I would just bend one up myself like Jamie said.
readjusting?! dont like the sound of that...sounds hard j/k. Ok I guess I will be able to put it on, but what do you mean by re adjusting and how do you do it? Thanks! Yeah im a go ahead and try benging the line myself, shouldnt be too hard.
There are only 2 adjustments to make on a 6 cylinder carb. The first is the idle mixture. It is a screw in the base of the carb. You probably won't have to mess with that unless it runs so rich at idle that it makes your eyes burn/water standing behind the car at idle. The other adjustment is the idle speed. There is a screw with a spring under it right under where the throttle linkage hooks up. To adjust this, get somebody in the car to hold the brakes and put the car in drive. Turn the screw out until the engine slows down enough that it starts to run rough. Then turn it back in until it smooths out. My car idles between 600 - 700 RPM.
take the old gas line with you and get one to match. as Jamie said "get it longer than you need" . you will have to cut one end off anyway...frank...
what do I cut it with? For the idle speed the car has to be on right? Can you show me a picture of the carb? Ive seen two of those screws with springs, how do I know which is which? Looking from the front of the car, the one on the left side is the idle mixture and the one on the back of the carb is the idle speed right? Thanks alot for the help!! hold on, the reason the car wont turn on all the time is probably the carb right??
A tubing cutter is best, but if you really really had to a hack saw will work, just make sure all the filings are blown out before you use the line.
I'd take a pic of mine, but it would probably be farily worthless to you since your '70 likely has a Carter YF, and the '74 engine in my '72 has a Carter RBS. I have also removed and done a few things to my carb in the name of gas mileage that would probably only confuse you. Say you are looking at the carb standing on the passenger side of the engine bay. The screw that goes into the base of the carb closer to the front is the mixture screw. The one closest to the rear of the carb and right by where the throttle linkage hooks up is the idle speed adjustment. The car needs to be running and in drive to set the idle speed. Like I said, have someone start the car, set the parking brake, and hold the normal brake and put it in gear while you adjust the idle speed. Like Dave said, a tubeing cutter is best to cut the tube. But I have also used my dremel tool with a fiberglass reinforced cut off wheel...
update-- I just go the new carb!! havent installed it yet but I have a question: Is the choke suppose to be open at all times? I mean the choke plate thing at the top of the carb where you screw in the wing nut for the air cleaner. thanks!
It should be open about 3/8 of an inch when it's cold (maybe less, there is a setting) and once the engine warms up it'll open.
so right now it stays closed. I havent put it on the car yet. So when its on the car and it warms up it will open by itself?
