2 quick ea81 questions


Recommended Posts

New owner here, looking for some help.

 

1. Does the ignition control module need thermal paste? Mine from autozone came with some; however, it doesn't really look like the bottom plate on the module rests against the brake plate in any solid manner.

 

2. I've heard talk of a secondary fuel filter, or vapor separator, in the engine compartment. I've traced the fuel line all the way from the firewall to the carby, but can't find a filter (other than the one under the chassis by the fuel pump). Did all ea81s have this secondary filter?

Thermal compound wouldn't hurt anything even if it's not used on a flat surface. Manufacturer probably added it to all their product whether it's needed or not.

 

I've had at least 15 EA81 cars over the years in my family from '82 to '86 models and they all had a vapor separator in them. I could send a pic of the one in our Brat if you like.

Where does the vapor separator go? To the canister?

 

The tube to the right of the picture is input, comes from the firewall, the tube on the left is output straight to the carb, the tube coming out of the top splits off down below the separator. One of these tubes then leads back into the firewall under the spare tyre, and the other to the carb, from which I can only assume to the canister, but am not able to tell without taking off the air cleaner. It's getting dark so if you need I can find out for sure in the morning.

So the only line I could find going back to the fuel tank comes out of the canister. I teed the vapor separator into it, and managed to fill the canister with gas. Think I did something wrong there...
