is there any user out there who has ran a 350 2bbl on their 22r? mines coming in the mail next week and im trying to get everything ready for the swap but ive got a few questions. first what vaccume lines will i need for the new carb, second how should i run my throttle cable, and third will there be enough clearance to shut my hood with the new carb plus the 1 inch adapter and the air cleaner? any pics would be greatly appreciated, the thing im most worried about is the throttle cable. i dont know if theres some kind of kit to make it work or not. this is my first real mod and i want everything to go as smooth as possible. thx ^^

 

well thanks for all the help....ive got the carb all hooked up...ive drained the gas tank, replaced the rubber in the fuel lines, new fuel filter, throttle cable, choke cable, egr block plates are bolted on..everything should be good but for some reason im not getting fuel to the carb. the fuel filter near the gas tank isnt filling up either. signs say fuel pump but i think it may have something to do with the bag of crap i yanked out (egr). im going to get a new pump today. can anyone post a pic of their desmogged 22r, something that shows the fuel and vaccume lines so ill know what i did wrong... im kinda stuck here and its driving me crazy.

 

On my 22r there is a double fuel line that comes down from the mechanical fuel pump under the intake and comes out just under the passenger side of the intake, 1 line sticking out straight to the passenger side, this goes to a return to the tank. The other part of the double line that goes back diagonally toward the corner of the engine bay needs to connect to the main fuel supply line. The first time I got mine fired up after redoing all those lines I didn't hook up the return line and ended up with a puddle of gas all over the floor so make sure that one is hooked up too. The other thing is that if your fuel line was completely empty it can take a while for the pump to prime it For mine I kept it going by pouring gas from a little cup a little bit at a time into the carb just to keep it going for a bit. It took longer than I expected.

As far as the vacuum lines, what all do you have left to figure out?

 

Fuel filter near gas tank not filling is the only thing you should be focused on right now then..
hot wire the current pump (speaker wire if you hafta) just get 12 volts to the connections there and see if it turns on or not. may not need to replace the pump. also make sure you have the return line and feed lines in the right spots... easy to swap.

 

fuel pump is mechanical, im pretty sure the lines are all in the right place...can it run without the charcoal canister? i think its the pump, im replacing it 2morrow so ill know then. ill post results when im done. what i could really use is some kind of diagram showing the 3 lines coming from the tank to the pump. also what do i do with the metal line that leads to the charcoal canister since the canisters gone.

 

cap off the extra line.

 

i replaced the pump and still nothing...

 

ok this might seem dumb but.....

so your getting no fule past through the pump into the carb? right?

this is what I did when I had a bone dry system and it seemed to work for me

unplug the coil (no spark) and keep turning it over with the line undone (might want to have someone around to help) then ..(this part sucks... lol) suck on the fuel line to help fill all of the lines and to prime the system funnyup: get it.... lofl lol )

I felt it start to bubble a bit.... then started getting fuel after a while

hope this helps ....

it took me a min. to get fuel also . I even thought my pump might have gone out also .. but it was just not primed

good luck

 

Same here. Like I said in my first response, it took longer than I thought it would to get the gas primed. I'd suggest you pour some gas in a spray can cap or something and maybe have a friend work the gas pedal and pump it while keeping it running with a teaspoon or so of gas at a time, maybe even for a minute or something. I forget how long it took exactly but it took a bit and I was also starting to doubt my fuel pump. Now it works fine.

 

gas isnt even getting into the filter at the tank tho. in order rear to front what are the 3 lines? mainly which one supplies fuel to the pump??

 

Then manually siphon it to prime it through the filter. Remove the supply line from the double rail under the intake and attach it to a double barb connector and put a clear hose on that so you can see the gas flow. Then make sure you are uphill with the siphon hose so you don't end up with gas rushing toward your mouth. This is a good general procedure to follow for siphoning, always use a clear hose, and keep uphill of the container you are siphoning from until you are ready to let it flow into the new container. Saves you from nasty tasting gas in your mouth or even worse, gas burps... You don't want to experience that.

 

yeah gas burps are the worst!!!

 

it should be primed by now. i have 2 clear fuel filters, one at the tank and one btween the pump and carb. the one at the tank is full and i can see the one btween the pump and carb getting fuel but its not filling. i have to keep adding gas to the carb to get it to start and to keep it running im squirting gas into the carb. shouldnt the filter by the carb be filling?

 

You are pumping the throttle too? I'm not trying to leave you hanging. I just can't figure what the issue would be. I'd throttle it more and do a bit more of the same. Before you said you can see it getting gas to the filters I was starting to wonder if you had done recent head work, timing, or cam work so that somehow you could be missing the eccentric lobe bolted on the end of the camshaft that pushes the fuel pump arm, but now it sounds like thats not the case as it would not pump any fuel whatsoever. You still might try the clear hose and siphon idea and make sure you get steady flow that way. Otherwise I am at a loss for the moment.

 

idfk wat it is either....im getting fed up with the bs. if any1 can think of sumthing just post, ill be checking the thread over and over till its fixed. thx for the help

 

Beings you replaced the fuel lines, are they connected correctly, 3 lines on the tank, supply, return, vent, the supply should be the one that comes out of the sending unit cover.
The mechanical pump also has 3 lines, I don't have one to look at to tell which is the supply for you, so possibly you don't have the pump supply connected correctly to the tank supply so it can't pull any fuel. If you plugged off the other lines and capped things off, did you replace the gas cap with a vented cap? the tank needs to be vented or the pump will not pull fuel, or at least only a bit until the tank has such a vacuum that it won't allow any flow.
If connections are correct then possibly a bad diaphram in the pump.

 

the lines are hooked up right and the fuel pumps brand new. im getting fuel now, the first filter is full but the one bteen the carb and pump wont fill. i can see gas entering the filter but its not filling. the tank is vented also. im stuck...

 

I don't think you will see the front filter fill completely, beings all the fuel lines are new, new filters, new pump, connections correct, then I would focus on the carb itself, sounds like possibly the accelerator pump in the carb is not working, bad diaphram in the acc pump, or lever is not correctly seated. moving the throttle linkage by hand with the engine off and looking down the carb throat, you should see a healthy stream of fuel coming from the shooter nozzle if the pump is good.

 

the carb is brand new also, it doesnt seem like theres enough fuel getting to the carb, almost like a partialy blocked fuel line. fuel just drizzles into the filter infront of the carb a few drops at a time

 

But that doesn't tell me if fuel is actually filling the float bowl and the accelerator pump is actually spraying fuel when the throttle linkage is opened.
A fuel pressure test gauge on the carb side of the pump would be a good starting point to see what the actual pressure is while cranking the engine.
