Does anyone have any info. on the fuel system on a 7FGU25 serial 79508? It idles rough and cuts out when you give it the gas and then comes out of it if you hold the gas pedal all the way down. Smells rich at idle. unable to adjust the carb. enough to get a good idle. Is there a map sensor on this engine, looks like maybe one mounted by the carb.? Thanks. Keep those trucks a rollin. s.tjones at yahoo dot com

Did you drain the regulator? The Asian regulators have a drain on the right hand side that is a 12mm plug.
yes you can have a regulator defect or it have a vaporizer you can check it is oke ,
possible the engine have to much LPG for working so you set the vaporizer settings right.
LP, did tune up, think it's a fuel issue.
is it a gasoline truck or an LPG truck?
Probably need to adjust regulator. You will need a handheld to properly adjust levels.
