I just ordered the sensors and will replace them, Thanks, Ozzie

Thanks, I really appreciate the advice and will check those sensors.

Any way to slience buzzer short of disconnecting wiring harness? It buzzes constantly even though everything seems to be ok.

Good morning Andy, I saw this old post of yours and was wondering if you can help me diagnose my fuel pump. I have s 1986 M923A1 855 ci Cummins non turbo and it lost power a few weeks ago. I've replaced fuel filter, cleaned fuel tank and even put an electric fuel pump to supply the fuel pump and...

I ran the knurled knob in and hooked up to a 5 gallon can of diesel and installed an electric pump. It runs lousy and will not rev up. Sounds like running on 2 or 3 cyl. Knob in or out makes no difference. I have fuel flow all the way back to return lines to tank.

I ran the knob in but have not hooked my fuel back up to test. Will find out this weekend. Thanks for all your help.

Will try the hose next. I'm not sure about the knurled knob on the front of the fsov. Sorry for the ignorance, but I'm brand new to the 5 tons. Thanks and will post findings.

On my truck, I bought it about 5 months ago and did all the normal maint which included fuel filter. It was a disaster and ran much better after the maint. After about 6-8 hours of running over 8 weeks, it started running lousy and then died and won't restart. White smoke coming out of exhaust...

Have you figured out your fuel problem? My truck (1986 M923A1 with non turbo 855 ci cummins) is doing the same thing you described. I removed the tank to clean and temporarily installed an electric fuel pump to a 5 gallon can and did not help at all. Having a horrible time finding someone who...

Really enjoyed your article and I am considering this update myself. Have you tried everything since installed and I was wondering how it is all working? I'm new to the 5 tons and have my first M923A1 and I am having a great time playing with and working on my truck. Have had no major issues...

Where did you get your top? I tried lots of different popacom's but found nothing. Thanks

You were dead on. Fuel system was the culprit. Thanks again

I'm fixin to try the Dexron III fluid myself. Modulator cable seems good.

Thanks, will get that checked today. Appreciate the help.

Anybody having any problems with M923A1 stalling and not revving up until engine has run a full 20 - 30 minutes. If I take off too early, the engine slows down and acts like it's only running on a few cyl. It will not move. After 30 min or so, seesm to run great. Drove it for 2 hours getting it...

Sorry, new stuff to me. We all got to learn.

I have an M923A1 and I'm wanting to figure a way to prevent someone from driving off with my truck. I installed a starter interupter on my F-250 but not sure what to do with this 24 volt system. Thanks, Ozzie

How much is the kit?
