mostly fuel stuff

Not much going on on the fox body project.
Honestly haven't had much time to enjoy driving it. Family/work gets in the way of wrenching and cruising.
I have been working on the fuel system for the last few months because of the lean pops on startup before it's up to temp.

I rolled the dice on a cheap set of ev1 24lb injectors. At the same time I got a injector tester. So the injectors all ended up being fine but the tester lasted 2 tests and then made me think the injectors were bad.  That discouraged me for 2 weeks but then I put the injectors straight to a 12v source and they all clicked just fine causing me to go back and check the tester. a multi meter showed it wasn't pushing more than 4volts on any of the tests. 
When I went to install those I noticed a great deal of oil in the upper intake. Pcv can be a problem on foxes so I installed a cheap catch can between the pcv and the intake. That's been dry so far so I need to investigate further.
i finally broke down and put the fuel pressure tester on the shrader valve and ran some tests.
No vacuum was 40lbs so the pump is good but with vacuum I only saw 32lbs and that is my lean condition.
So I bought and adjustable fuel pressure regulator from rockauto because it's the same you'd get from LMR just $10 cheaper. After I installed that and set it it hangs around 38lbs with vacuum.
I reset the timing and added a few degrees probably around 14 initial and did a base idle reset. Honestly it's surging more than it used at start up, but I'll tune it out with over time. 
I also got a nice tigged 2L coolant over flow tank that doesn't fit anywhere so back to the 20oz cylinder with the peanut butter jar backup. I just got tired of coolant smell all the time, cause the plastic tank never sealed well.
