So I've spent a fair bit of time scrolling on the forums looking at how most solved this issue and have a pretty good bearing on where to go but I'm hoping I can get some educated guess' what the culprit could be..
My new to me '84 Bj60 has been an absolute trooper this year, bought it on Vancouver Island when I was trying SO HARD to get something a little more modern and turn key and less of a project than my '74 40 series ... I guess it's new enough
. Anyway, put down about 20k-ish kilometers and she needs some lovin'. Recently I've been having air leak issues, replaced the primer pump with a Bosch unit and thought I had solved it but after a couple weeks it stalled on warm up - after an hour of priming I finally got it going and made it back home.
So it runs fine when the weather is fairly warm, about zero Celsius and up, but soon as it gets -5 or colder I get air leaks until I get it warm enough that it goes away.. Once it's at operating temp the issue is gone for the rest of the day I can leave it off for several hours and get in and go with no dramas. I found one thread that someone was talking about heated fuel filters have an o-ring that can cause leaks but that was 80 series related - note sure if the same can be said for a 3B?
With all that being said, if it goes away after the truck warms up, this would tell me whatever the leak is it's somewhere under the hood? I've read a lot of threads that people found their leaks around the fuel tank but I can't see that being my case. My plan is to get to the fuel filter, check the fuel line off the banjo fitting, and water separator - every time I bleed the air out first thing in the morning the initial spit of fuel looks pretty nasty. I'll be tackling this in the next couple days, hopefully someone with a little more toyota diesel knowledge can diagnose my dilemma from their end of a computer 🤞

I tossed some fluid in and was able to get a little bit of pressure at the bottom end with a couple pumps so I double clutched around the block with no issues besides my double clutch skills, or lack thereof.
