so i found an aap that is sold individually but will it fit? i found it here would it fit and 84 p/u? http://www.jegs.com/webapp/wcs/store...10002_11640_-1

 

if my memory serves .. the aap is a "triangle shape" only 3 holes . the acceleration pump is 4 hole and square .

edit .. found a pic for you .

 

I swapped out my aap and still having problems with cold start do I need to swap out the acceleration pump next?

 

Swapped out accelerator pump today so I will fire her up in the morning and see what happens

 

just fired it up hit it 2 pumps and it fired up and stalled hit it 1 pump and it fired back up. When it gets cold in a couple of days that will be the test? I replaced the the pump diaphram.I know the old one was 24 yrs. old but it looked o.k. to me but there might be more to it than meets the eye?

 

After swapping out the aap and the accelerator pump diaphrams it is cranking great but it has been every day.and in warm weather it is fixna get cold and it will sit next week while at work that will be the real test. I should of swapped them out years ago.

 

was it hard to swap them out? am i just swapping the diaphrams? im confused...

 

also if i pump it even once b4 starting it...it takes even longer. seems almost like its flooded after one pump...

 

They are just diaphrams with a spring easy to change. They didn't seem to have any holes in them but I can tell a differance. I bought a carb rebuild kit from autozone and have been using parts off it. I use to have to pump it ten times then it still didn't wan't to crank

 

i bought a rebuild kit to from auto zone but i was just unsure about it. yea if i go out and try and start my truck it cranks and cranks for like 30 seconds until it catches and fires up, then runs like a dream except when i floor it it boggs down then speeds up.

 

you think if i replaced those things it would help? how long would you say it took you?

 

Not long just study the diagram on this page of the aap and accelerator pump or the rebuild kit should have come with one also. both of them are on the front take your time and it will be easy. Let me know the status.

 

Do you let it warm up for a few minutes then pop the gas and it idles down. If I take off in mine and its cold it would bog. Is it o.k. when its warmed up?

 

yea it only bogs when its cold...and has a really hard time starting cold...but after it warms up its fine, starts fine and barely bogs.

 

Yes swap out the two and you will be pleased. it still may or maynot bog when its cold but if you want it to last forever I wouldn't drive it cold. I just went out and tried the 83 it is 38 degrees and I gave it 2 pumps and it fired up like I shot some cocaine in it.

 

haha ok i plan on doin that on monday...i will keep you posted thanks for your help.

 

i ran in to a problem...how did you get to the 3 screws on the aap? its like 4 inches of space..any special screwdriver or something? HELP

 

I have a screwdriver with the pac of innerchangable ends that go in it. I just got the one that fit the screw and clamped some small needle- nose vise-grips on it and made a sideways screwdriver. Like I said its a be patient with it job. I found my cure when I did the accelerator pump on the other side but its a good idea to do both

 

oh i see... i didn't even think of that. good idea i will try that tomorrow. thanks

 

well i swapped out my aap yesterday was very time consuming...but this morning,i just turned the key (w/o pumping the pedal) and it fired up real quick..then died....then i pumped it once and it fired up again and stayed running...is this just normal with carbs? also i couldn't tell if it was gas or water coming out of my exhaust..is that normal too?
