You have any pics of the hoses that hook up to the PCV, crankcase filter, and air cleaner. I'm trying to figure out where my crankcase filter hose hooks up. I have an elbow on my passenger side valve cover but can't figure out how to connect it to the air cleaner. My PCV is in the oil filler/breather on the driver's side and it has a hose hooked to the base of the carb. Any pics would be helpful, thanks.

Best pic I have of the pcb inlet on the back/base of my old carb. See the little hole there? More pics at my supermotors account under motor rebuild. Cheers.

Drawing of Vacuum hoses 1979 400/C6/AC

I figured I would try and make this something that an "average" person could understand. Dealing with the California smog police and the cost of failing a smog test is the pits.

I have a 1979 F-250 4x4 and a 1979 Bronco, both with a 400/C6/with AC. I followed the vacuum hoses on both of them and they were the same. I made a sketch of one, because the vehicles are at different locations and I wanted to be able to confirm that they were indeed the same. Here are my sketches with some added notes. Sorry for the line down the middle, my scanner has a bug in it. I hope they help....

I want to confirm one thing on the Motorcraft 2150. The EGR is connected to the port on the back side of the carb, on the driver's side. My question is, what type of vacuum does this pull? I hooked up a vac gauge, and I didnt get any vacuum. I would guess that ths would be ported, and would have vacuum increase as the engine rev's higher.

I assume that this is the correct port, but what other port could I hook it to?

Time to revive this thread. Anyone in CA have a concours correct fully smog legal eng

Time to revive this thread. Who and I know that there are a few out there in CA who have a fully restored smog legal or all original engine bay. What would it take to have you post a detailed picture spread of what's what on your smog laden baby? Pictures are worth volumes and it is sometimes easier to just copy what's blatantly in front of you especially if you are diagram illiterate like me. I have a CA F250 2wd 460/c6 combo A/C Holley 4bbl stock carb. PO died and so in law tired to revive my baby. Could not get the original carb to work so he swapped in a no smog edelbrock carb. Barely starts and has most lines disconnected so i would love to SEE what goes where. Any help would be sweet. I have the Clymer repair manual and it sucks.

LOL.. I am so freaking close. I have 2 vacuum lines that I don't know where they go, then I will have a complete Ca smog legal full on 77 F250. I have searched and searched. I found where one goes, then I just found another one today...Have NO idea where it goes, and the other one is coming off the back of the carb. It was capped off. I just rebuilt my carb and found it when I got the carb off. If I could get my camera that far down on the back, I could take a picture. The other one I just found today is really long and thick. It attaches to the purge canister, but there is no where for it to go on the upper side.

I will try and get pictures. This thread has helped a lot to make sure I have everything in its correct place.

Try RockAuto and LMC for the vacuum delay valves and the ported vacuum switches.

Thank you.... I actually found most of the EGR load control valve and most of the vacuum delay valves. I'll post the information for anyone else who need them. Seems like they have most hard to find parts. Talk to Sid... he was very helpful:

So I just got rid of this the only line hooked up was to the gas tank. Can I seal off the gas tank or even better can I get a 33 gallon upgrade with no emissions hole?

If anyone wants a good book to help you really understand how your emission system works, this is a great resource. Pick em up off of EBay or Amazon, real cheap.

I have read through this forum and it's been a wealth of information but I still have some questions that I couldn't find answers for. Since the previous owner removed everything emissions and trashed it all I've been picking everything I can find out of the junkyard. Picture is my emissions sticker that I have a couple of questions about.

1. It looks like I should have two charcoal canisters and not the normal of one that I've seen, can anyone confirm this?

2. Four port VCV located on top of the thermostat housing, what color/temp should this be?

3. Two port VCV located on the side of the thermostat housing, what color/temp should this be? I believe it should be green.

4. Dashed lines on emissions sticker, I'm thinking that these items were "optional"? I'm I correct on this or off in left field?

5. What is A and B pointing out other than a connection?

Thanks for the help.
