Alright, I finally found the 18ga orange wired fusible link. I pierced it on both sides of the fusible link, used a multi-meter with audible continuity tester...and that fusible link tested as fine.
So, what else needs to be tested?
And since I am swapping pumps anyway, if the old one is indeed dead, I could care less.
Here is a question my roommate posed...can we pull out the old pump, hook it up to the battery positive and to a ground and test if it still functions? If so, then I know if the old pump is dead or good. If it is dead, I will just drop in the new 255lph walbro and dyno tomorrow as planned.
