    Does anyone have a good method for checking the fuel pressure on a TBI system? My TPI engine has a Schrader valve on one of the fuel rails that makes it easy to check the pressure. But the TBI's don't have that nice little feature. [​IMG] Actron sells an adapter, with a gauge, but it's $75!!!! [​IMG] You can see it here: <a target="_blank" href=http://www.actron.com/cgi-bin/web_store.cgi?page=cp7817.htm>http://www.actron.com/cgi-bin/web_store.cgi?page=cp7817.htm</a>

    Got any ideas about buying (or fabbing) just the adapter?
