I need some help with 5200 carb

neil_home · Jul 29, 2008

I am putting together a 79 2.3 with the 5200 carb and I have no idea what all the connections are for. Is there anyplace I can get that information? I also have an earlier 5200 that doesn't have as many connections. There seem to be two gas inlets a few vacuum lines and some electrical connections. I want this basic. As basic as possible. One gas connection and the choke (electric) but what do I do with the rest?

One other thing what is the small outlet on the in side of the manual fuel pump for?

Agian if there is something I don't have to connect, thats better.Basic

Go to a local library and go to the technical section and they should have a whole set of Mitchells manuals.

You should be able to track down a exploded view of the carb. You wont be able to check out the manual but you should be able to photocopy the page.

Other option is to go buy a Haynes manual. I personally think the Haynes manuals are better than a Chiltons.

I have a MOTOR manual from 77 and it has an exploded view of the carb in it. It doesnt say what connects where thought. And I couldn't find anything about the fuel pump extra fitting. Do you think the other manuals will have better discriptions? I can check next week when I get back to work. I work in the sub basement of the library at Uconn. Not for the library.

I will see if I still have my Haynes manual for my 79 carb turbo Capri. It had a whole section on the carb.

Any chance you can post a pic of the carb and add arrows to the parts your trying to ID?

I got some pictures. I only did the carb with the electric choke. The first picture that will come up is of the pump. Just hit next to go to the carb pictures. There are two. It took me a while to do the arrows and text. Now I feel like a bigger idiot. I don't know where this stuff on the car parts go and I can't mark up a picture to ask.

Thanks, Neil

All I could find

First pic: Looks like a vacuum or atmosphere reference for fuel pump. Is this a carb turbo model?

Second pic: one on left IIRC is vent for fuel bowl or its the vacuum hookup for anti-dieseling solenoid. Arrow on right is the fuel filter inlet.

Third pic:

1) Not sure.

2) Electric choke plugin

3) Vacuum port.

Found some online manual info you can browse through, might help.

Another good place to ask is Four Eyed Pride. They specialize in 1979-1986 Mustangs.

Thanks for the info. No it is a 79 bobcat staion wagon 2.3 L 4 speed motor. Stock. I am removing anything I don't need to make it run. I have a 2100 I could put on it but I think I like the idea of the progressive 2 barrel. I want some gas mileage. Is going in a 63 Falcon. I have a turbo car I am going to strip and some day upgrade this to a turbo 5 speed.

I think I responded to you over on foureyedpride, but if I didn't, here are your answers:

Picture 1: this is where a fuel return line would attach and go back to your tank. To eliminate this, use a later (1984-1986) 2.3L fuel pump. They don't use a return line.

Picture 2: On the left is the bowl vent line hookup. Cap that off. On the right is a rusty fuel filter. Line from pump attaches here.

Picture 3: #1 is choke pulldown. Attach a line from there directly to manifold vacuum. #2 is the choke connection. Connect to the rear of the alternator or a good switched 12V source. #3 is for EGR control. If you're not running EGR, cap it off at the carb.

Hope this helps. If you need more 5200 info, I've got plenty. It's what I'm using on my 86 Capri right now. I also have 3 or 4 spares lurking around in different calibrations.

Thank you and yes you did. I have abandoned the carb for a short time. I injured myself and cant get to the garage (a terrible fate). But have been thinking about it. I have some more questions if you don't mind.

Shouldn't a vent be left open? And what is the regulator looking thing by the vent?
Next the choke pull down vacuum seemed like it might have gone to a thing on the manifold that looks like a temp vacuum switch. I would guess that this opens the choke when there is no vacuum like full throttle? And if the electric choke has power all the time what opens it normally, unless full throttle vacuum? There will be no EGR. I will also have to find a fuel pump, but would rather find a solution as to this is suppose to be a temp solution while I finish my other car and prep the efi turbo 5 speed for this one.

Thanks again. I wish I had something to compare it to but I only have my 30 year old memories of my 76 capri. And I have a problem with remembering things from last week.

The bowl vent can be plugged off. It's basically a vent for the vapor in the fuel bowl. The line that would attach to it connects into your PCV system through a bowl vent switch (probably long gone on your car). Capping it doesn't affect the performance of the vehicle, it just allows the fuel vapor from the bowl to escape back into the air cleaner instead (you'll get a very slight gasoline odor at times). As for the choke pulldown vacuum line, each calibration is different, but most I have come across have that going direct to a manifold vacuum source. The purpose of that is so that immediately after the vehicle is started, the pulldown pulls the choke open slighly so the engine doesn't flood out. The electric choke should only get power when the key is in the "run" position, which is why it is generally connected to the rear of the alternator (only generates power when the car is running). Once the electric choke is hot, it won't close from low vacuum due to hard acceleration.
