Found fuel problem, now how do I fix it?

i definitely agree w spare about the e-10 being SLOW.... I was more looking at it as the secondary cause rather than the solution

Spare, do you think the acetone would damage his fuel sending unit? might need to make up a temporary delete plate to put on while cleaning. Probably need at least 10 gallons in there.
Definitely test with a vacuum gauge. Simple and effective.
