I'm trying something similar but with the AmsOil dual filter w/bypass. However I'm having bit of a problem of where to mount it. Their instructions say it shouldn't have more than four feet of line to/from the block and there just isn't a good place within that distance to mount it well. It seems to me that mounting under the door on the frame rail could cause problems with priming when changing filters (the lines thus draining) since there would be a lot of oil line to fill before it builds pressure. Unless, of course, one prefills the entire system with every filter change, which would be a big hassle. What are your thoughts? With your dual filter set up, how long does it take to prime everything on start-up? Would you be willing to show where you tend to mount it?
@leroydiesel5647
@leroydiesel5647 День назад
Just prefill the oil filters if you are worried. Mine mount close to the lift pump, I don't have a picture as on my truck that space is taken by an oil cooler.

@@leroydiesel5647 I know that Leroy I was referring to the electrical box idea to hide your gas hook up there at your chimney. That’s what I was referring to at the side of your house.

That’s what I was referring to the electrical box hook up like you did, perfect they sell generators that run on natural gas as well.

We have HVO100 here in Bavaria. It is synthetic Diesel made from waste vegetable oil. It has insane Cetane numbers and produces less than half the amount of soot. I am running a fairly modern tractor engine (with DEF) with this fuel and I love it. We are working inside a riding hall and despite the bad ventilation, there is no noticeable effect from the emissions. I am never going back to the old diesels and the regular fuel.

Hurricanes suck because it knocks out everything infrastructure wise and it was 108° index today without air conditioning. Anyway I'm hoping to have power later this evening or maybe tomorrow we're having another lightning storm here so the workers probably had to delay what they were doing in the video.
