Weber Hook-up

[superc_1]

Going to put my used weber on today. I was wondering what do you do with the (1) fuel return lines and (2) the hose that comes out the top of the valve cover that hooks to air cleaner? I have the adapter plate, but is it easy to get the studs out of the old manifold? Anything to look out for? Pictures? Thanks in advance.

Here is what I did:

 

 

Here is the Hitachi set up to compare:

 

 

I don't have any emission stuff on my 73 620 so I am not sure where you would reconnect the breather hose......I am not too sure that a Weber will be helpful in a DEQ inspection.

 

I hope this is helpful.

1) nothing. it may still be venting the gas tank?(not familiar w/ trucks)

2) i put an adapter w/filter on the bottom of the air filter plate and connected it there. essentially the way it is stock.

1. The check-valve that stops fuel flow into the carb is stronger on the Weber than the factory carb. You can choose to not run a fuel return line.

Or, you can buy a 2nd fuel connector and remove the plug that is opposite the fuel hookup line on the carb. Then the fuel runs through the carb and back to the tank. This will continually flow the fuel through your fuel filter and potentially keep it more clean and less likely for blockage in the main line. (I recomend this)

 

2. Hook up that hose to the underside of the air filter plate on the Weber. You'll notice a hole in that bottom plate. Hooking it up there is where you need to get creative.

 

3. I had to remove the valve cover and EGR valve in order to have room to get at the four nuts that hold the factory carb down.
