T 248 code is a speed senor at flywheel, and as for your tech rebuilding regulator, it will act up again,How much time did he take to rebuild regulator plus cost of rebuild kit. it may of just been cheaper to just replace it. we use the same regulater as we use on the clarks regulator, linde s are to high price and not a noticable difference in running. also to after any changes to fuel system , it is a good idea to hook up to laptop and hook up to pathfinder with engine cord and calibrate fuel.Flywheel could have a chipped tooth. T 235 has to do with direction. Hook up a lap top and calibrate pedal sensors

I know T is for traction, my Linde book is at work ill have a look tomorrow unless anybody else knows the codes.

Thanks guys, My tech was able to rebuild the regulator and the chattering has stopped. The fuel is flowing but now the truck seems to be in limp mode. It is showing code T248 and T235.

If it is this gas shut off valve then they have been modified, ring Linde with the truck serial number & get the latest part number.

Had to change one last month on a H40, comes as one big lump ready to bolt straight on & there surprisingly cheap as well.

The Impco filter kits for these units are really cheap to.

If this solinoid is blue in color with a domed component piped next to it and two wires attached to it, this is the electric fuel shut off. If this is the case, the engine should have stopped running after approx 60 sec. and you are need to look at an LPG leak at the valve.

Hi

This solenoid is it blue in colour with a connector plug with 2 wires in?
