LOL, I don't dare drive my car anywhere with it operating like this. I guess I could if I have my 3mm Allen wrench with me but I really don't like changing the mixture just to get the thing started and then tweaking it again to keep it running right. Anyway, I ordered a different fuel pressure testing kit from Amazon (
https://www.amazon.com/gp/product/B008FJXA3M) this one has comments on it from DeLorean owners saying that it works for measuring both values. When it gets here I'll take some pressure measurements like Dave suggested and then, if nothing is awry, likely pull the FD and send it in for replacement.
