As a new FJ40 owner I took my truck to a mechanic to get the Weber 38/38 carb tuned that the PO had installed. He did a great job with the tune, but a couple months later I noticed I had trouble revving the engine and later determined it was a fuel leak at the fuel inlet on the carb. The mechanic had removed the original pressed in fuel inlet barb because he said it was cracked and he installed a hose union with some sealant. The sealant on the union failed and thus the fuel leak. My question is can I replace the pressed in fuel inlet barb or do I need to thread the carb to replace the inlet barb? I can not find a press in inlet barb to purchase so that may be a no go anyway.

Not sure what that is. Got a pic?

But anyhow, a while back, there was someone here talking about removing the pressed in barb fitting and tapping the carb. I always wanted to do it to my Weber so I could run a hard line to it. But I changed carbs before I did. Whoever it was, I remember them saying it was tricky tapping it and you had to be careful. It may have Weber Sarge, but not sure.

Hmmm. Is that really a 38/38? It doesn’t look like the 38/38s I’ve seen. I didn’t realize Weber made any carb that fit an FJ40 manifold without an adapter, but what do I know. I’m sitting back to learn on this one.

it is a 38/38 based on the manual I was given. It does have an adaptor plate on the intake. When I had the carb tuned the adaptor plate had to be machined flat to eliminate a whistle.

Ah! I was thinking that was a phenolic insulator (between the arrows) that the PCV hose was going into. Looking closer, is that the adapter? Or rather the typical Weber two adapter plates?
