Dahl owners, change your filters
Just a reminder to change your filters if you aren't running a vacuum gauge. My Dahl 100 creates about a 2 inch of mercury vacuum at idle with a clean filter. I looked at it the other day because I could hear air cavitating in the pump and it was pulling something like 22. Yikes. Changed the filter, eliminated the cavitation sound (might have been drawing air at the fittings/clamps), and now I am back to 2.
Don't forget to burp it either!

If pre-pump filtration was stock on these rigs, the biggest advice on the forum would be the after-pump fuel filter... or "Post-Pump Purifier".
In answer to your question, the vacuum gauge pre-filter and fuel pressure gauge post-filter would give interesting information... but it's not idle where the issue is.
