      February 27, 2018 at 2:09 pm Is it possible to use the following line for an oil drain line?? The blue oil line that drains oil back from a Walker airsep. It is supposed to be capped off when an evironvent CCV kits is install. Does it drain back to oil pan or crank case? I plan on installing the Envirovent kit.

    • Broken Throttle because of misalignment

      December 11, 2018 at 4:36 pm The broken throttle that was overtightened is also misaligned. The new cable was attached by a bolt and locknut. This placed the cable in a bind because of the angles. Any suggestions for a proper repair? The throttle is ordered from you and is properly installed. I need help with attaching the cable with correct hardware. Thanks, Retired Diesel Instructor

      July 14, 2018 at 9:48 am I have a 1/2 id fuel hose from the tank to primary filter on a dual Racor system. All hose is trident 1/2 id. What fittings would I need to install one of the squeeze bulb kits? The kit would have to tie in with hose. Like the design and appreciate the advice.

      July 15, 2018 at 6:40 am The fittings are 1/2″npt. The only thing that is 3/8″ is the tubing and squeeze bulb but you’ll be bypassing that for normal running via the valve positions. But you can run the engine via the 3/8″ loop for testing purposes, etc. without issue..
