The bubbles appear while on diesel too, though at a much decreased rate.

The overflow lines get wet when they're leaky, I've seen it before... they're pressurized, not under vacuum, right?

I was talking about the hard fuel lines from the IP to the injectors. If those were compromised, they'd also spray, right? A la drip test.

Hmm.. The hand pump works great, but I guess it could be leaking... in fact, I got diesel on my glove when priming the system... though that's normal, now isn't it?

It's so frustrating, I want to run the loop, but if I can't find this leak, I'll run a return line. Will an air leak like this sap power?

Oh, answer me this...
If there's air in the final (clear) fuel line TO the IP, will the air get run through the combustion process, or will it carry on through the overflow lines? I've always been under the impression that it'd go through the injectors and thus 'self prime' to a degree... if this is an incorrect assumption, things are different. Anyone know? Thanks!
