Grabbing $100 80k mile MW pump locally tomorrow.
And yes, I have been doing a little soul searching on the alternative fuel. I have several friends who have been doing this for a long time in 12 valves and this vintage Mercedes with great results. I don't think I'm ready to give up yet as I really believe my current issues are caused by a bad batch of veg oil. If I can't get it right with fuel I have more confidence in, I'll probably throw in the towel.
This is a $500 kinda rusty car. Big reason I bought it was to experiment with this stuff. I knew things like this were a risk, but I also enjoy the learning process (even if it does ultimately mean I'm better off running pump fuel.)

It depends on where you T ed in the pressure gauge. If you did that between the lift pump and the Spin on Filter if the filter is plugged the pressure will be high.
In order to take the filter out of the picture you need to put the gauge between the Spin on Filter and the Fuel Injection Pump Housing or install a new filter right before the test.
