CUCV Fuel Filter Base and Fuel Sensor Switch 008

My 1968 M1008A1 CUCV was getting hard to start at times or it would start and very shortly afterwards shut down for no apparent reason. After doing a search on the SteelSoldiers website I found the source of this problem to be a leaking "Fuel Sensor Switch" which is housed inside the filter base underneath of the fuel filter. I purchased a new filter base from and Ebay seller at a substantial cost thinking it would arrive complete and ready to bolt onto the firewall of my truck; unfortunately it did not come with the fuel sensor switch. Having purchased a new switch from "Owens Export" a while back I commenced the installation process only to break the new switch in the process. Once I figured out the problem I decided to share my findings with other members of SteelSoldiers - if I did this I am sure others will too! Apparently there were two different filter bases or "blocks" as some people call them and one of the differences is the diameter of the opening where the fuel sensor switch is housed. This indicates to me that there must be a different part number or part for the newer filter base when it comes to replacing the fuel sensor switch. Hopefully by watching this video it will prevent another person from destroying a replacement sensor switch which obviously was not made for one of the fuel filter bases.

NOTE: The newer "replacement" fuel filter bases have eliminated the need for the Fuel Sensor Switch so there is no need to place one in the "hole" where one would normally go. The use for the Fuel Sensor Switch was initially for the STE/ICE test set which is a multi-function meter requiring electrical feedback from sending units like the Fuel Sensor Switch. Since there were so many problems with sensor switch leaks, the replacement fuel blocks were "internally blocked" for the sensor switch and that is why these little white things do NOT fit into the newer fuel blocks. If you intend to use the older fuel filter base you can,and probably will wind up replacing the fuel sensor switch at least once while owning your CUCV.

@1984tls I see these on Ebay all the time - pretty cheap too. You may have the one with the fuel sensor that causes problems when the sensor goes bad. I bought new filter base a while back that did away with the fuel sensor and have not had probelms since. One thing I do need to do is install an electric fuel pump in-line because I have problem with the fuel draining back to the tank when I don't start my truck for long periods of time.
