here are some things that i'm not sure are relevant but thought i'd mention:

-p.o. had all new viton lines put on because he was running it on bio diesel (not sure if thats whats currently in the tank)
-apparently car sat for 6 months then he drove it for the last two months after sitting.
-when i had the filter off i pumped the hand primer and only a few drops would come out. not sure if that is normall or significant?
-there was a crush washer on the filter but my new one didn't come with one, so its the same one...don't know if thats a problem.

here are the things i'm going to look at tommorow and will report back but, in the meantime, i'm in a hurry to get this thing running so i'd love any advice on other things i should also be looking into.

-check filter/screen in the tank. maybe drain all fuel and refill?
-replace crush washer if i'm supposed to
-disconnnect line going into spin on filter and see if i get spurts of fuel when key is turned but car isn't cranking

if there is anything else to also look into let me know...but thats what i've gleaned from old posts so far. thanks so much!
