Heated fuel lines revisited

[zpiloto]

I did a search and notice that heated fuel lines has been discussed on this site but couldn't tell if anyone try it. When I looked in the top 10 only one mentioned having heated fuel lines. I saw over a 3% increase in FE when I installed them. Is anyone using them or is my gain unusuall?

What's your setup and all that? Is this scangauge verified or just tank to tank?

I'm running 3/8" copper tubing along the top of the radiator hose wrapped with aluminum foil. Water temperature runs between 190-205. Yes it was runs with the scangauge.

Not bad, I'll have to add this to my testing list for when the superMID shows up. Got any pictures?

[zpiloto]

No, I don't have the technology for that yet. Soon though.

can you describe how you ran your test? do you still have the data? it may be worth writing up an experiment summary. i'd be interested to know the details.

Here’s the data taken from the Scan Gauge. I did 3 runs on my usual 41 mile test loop. It was an A-B-A run. Temps mid 60’s winds south at 10-15 warm engine.

Actually with a sample that small it doesn't prove anything.
