2.4.1.2 Installation on a Tank with a SAE J1810 5-Bolt Fitting and Focus Tube
If a focus tube is used for a tank with a SAE J1810 5-bolt fitting, determine the depth of the
tank at the location of the tank sensor mounting hole and use a saw with a metal-cutting blade
to trim the focus tube so that it reaches 1” above the tank bottom when mounted. Remove any
burrs from the end of the focus tube after trimming.
Next, place the gasket included with the focus tube over the focus tube (between the focus
tube flange and the tank mounting flange), and then drop the focus tube into the hole so that
the bolt holes on the focus tube, focus tube gasket, and tank fitting all line up (WARNING – the
gasket must be properly aligned; it only fits one way).
Place the gasket included with the TLM100 over the focus tube so that the bolt holes line up
(WARNING – the gasket must be properly aligned; it only fits one way), then place the TLM100
sensor component on top of the TLM100 gasket so that the bolt holes line up.
Insert mounting screws into the bolt holes on the TLM100 sensor component, and thread them
into the tank fitting (the tank fitting may instead have studs installed, so in this case, install the
nuts over the studs), tightening them to a torque of 10-15 in-lbs (1.1-1.7 N·m). Do not use
threadlocking compounds containing methacrylate ester, such as Loctite Red (271), as they
will cause stress cracking of the plastic enclosure.
