Hello,
I just picked up an '87 IROC with the 305. I know nothing about TPI system. I do see an obvious fuel leak . Can you tell me what the brass nipple is that I have pictured. It is literally wet with fuel. Should it be connected to something? capped?

Thanks,

John

 

Could be schrader valve , crossover o-rings standard motor sk24 or flat washer under the test port it’s not brass.

Thanks. The fuel is in the center of the schrader valve, so that sounds like the culprit?

 

Yes don’t use one for a tire must be fuel rated. Simple fix

 

The old schrader valve had a broken spring. Replaced with fuel rated version and new cap.

Thanks for your help.
