So I built it based off the work of some Chevy guy on a Chevy forum if all things. So please forgive me for that. Took me about 1/2 an hour to build cus I had all the parts laying around. So before anyone says.... " wow that's going to blow up" ... I only used 25lbs of pressure with no clamps on my tubing and it was fine. I tapped everything and didn't use t tape. I DID glue the pvc together. I used the low oil presure sender for fill and the oil pressure sender for presure guage, but you can use anywhere that accesses the block journals and don't need a guage. When I hooked it up I filled primer with 2L oil and only filled my compressor to 25lbs just to be safe. I then hand cranked the engine over slowly and within seconds you could feel the whole engine loosen up and rotate freely. Eventually I got a bit of oil out the rocker. I did watch the clear tubing carelyfully incase it ran dry. You don't want to push air in.
So I shut the premier off and removed the oil filter and put a bit of hose and a bolt to plug the crank case breather vent and put the rocker cover back on and filled with 5l oil until it showed in the dip stick. I then removed the dip stick and put 25 lbs pressure into the dip tube with a rubber tiped blow gun and pressurized the crank case while turning the engine over clockwise? Anyway it was the rotation when it runs To prime the oil pump. That took a bit and would recomend doing that with the starter motor, but oil did barf out the filter hole. Once you fill the filter 75% of your system is primed, but more importantly the pump is primed and the bearing journals are primed. I would still turn it over a bit with glow plugs out just to get the rest of the air out of the system before starting it up. If you packed the oil pump gears before assembly with vasoline it's suppose to make a good tight seal and prime fast. I didn't! But sounds like an easy great idea. So I explained it in detail to avoid confusion which makes it Sound like a lot of effort, but actually it's not hard nor time consuming at all and you get another large rarely used tool you can store for decades. Wahoo.
I used:
4 inch pvc pipe about 18"
2 x 4 inch end caps
1 male air line coupler to top of tank
Some bolt on top you have a tap for for filling
1/4 npt pipe extension male male on bottom
1/4 inch ball valve
2 x npt brass barbed fitting
3 ft clear tubing
Gear clamp and bungee to suspend it
I was going to add 2 90 degree brass barbed fittings and a length of clear tubing to indicate how full the thing was, but I ran out of parts. Would be handy. I sort of measured by weight. Clean the thing inside like meticulously cus it's going straight to your bearings. No filter. I ran the thing for a while and watched for any junk just to wash the tubing before I hooked it up.
Edit. In hind sight a small inline fuel filter would have been cheap insurance against dirt.
