Weber carb K490 in a 2.8L

[Faceted]

Hello. I have a 1986 2.8L and am struggling to hook it up correctly. I put some hose clamps on what will be the fuel line in since it's going from hard line to soft but not much past that. Finally there was a orange piece (circled) that I broke off accidentally, any info on this? Maybe I could glue it back on?

 

Can anyone show me how to route the vacuum hoses for a weber k490 carb? I'm sure the jeep will start this year... month, I've let it sit too long.

I think the orange piece is a sort of vaccum switch. I may have one in can send you if you really want to replace it

I agree, looks like a vacuum harness of some sort. I’m really not familiar with the 2.8 but I have run a few Weber carbs in the old 258 engines. Not sure how much fuel pressure you are providing, but the Weber likes a fairly low pressure (somewhere around 3.5-4psi iirc).

Sure enough my spare engine has one. I'll pull if off and you can just pay shipping

Awesome, thanks. Please let me know what the nut size is for that fitting if you would.
