Huh. It goes up to maybe 90% of the total sweep and then no continuity. I'll dig around and see if I can find the specs for it. Either way it isn't reliable.

Started right up, of course, and the gauge is showing 5.7l, which is about what I dumped in. I'll contact the seller and see what they will do. Thanks for the spot-on advice.

What's the left vs right side?

Replaced fuel pump last August after identical symptoms.

OBC test 6 shows 0.0 left, 27.0 right and 27.0 total.

Looking over the excellent post from Andrewwynn:

About to pull both tank covers and see if I have leaks in the siphon hoses. Anything else I should be looking for? I hope the Delphi pump I bough last year isn't failing already.

What did the fuel gauge on the dash say? Did the low fuel light come on?

No light, gauge showed a little over a quarter tank. OBC showed 27l, clearly all wrong.
