Hi Dale,
Wow, thanks for sending along all this information on the Griggs tanks.
Truthfully, I'm not as up on the Seneca world as I need to be and didn't know about the Grigg tanks.
So you're now in the position to sacrifice 180 # for one more hour of flight time.
Do you need that kind of range for your normal mission?
Or is this for the occasional long XC?
Please keep me in the loop on your progress.
Thanks
Steve

Our shop has received the aux tanks from Griggs. We are currently awaiting install.
Griggs was were very responsive in the admin / questions phase - even weekends and after hours, timely in delivery, and honest about all the costs. No complaints so far.
We received the attached files in the purchase process. So no install or flight information yet. Filled, the tanks amount to ~180lbs, or about a person. (Install weight not known yet) This would seemingly provide one more hour of flight time at normal cruise fuel flow.
The attached factory-provided install pictures are somewhat difficult to view because they are rotated 90° L&R, but they provide at least some idea.

Hi Dale;
Sorry someone hasn't gotten to you sooner-I was hoping someone with actual experience would weigh in.
I do not have operational experience so the only help I can be is to refer you to www.griggsaircraft.com.
That's company that manufacturers and sells the tanks.
If you've found more information, I would appreciate it if you can find the time to post it here.
153 gallons is quite a fuel load.
Best,
Steve

Griggs 30gal Aux Tanks was created by Dale Egan
We recently purchased the Griggs aux tanks for our 1977 Seneca II and are having them installed this spring.
The plane currently has the existing factory 'extended range' tanks of 123 gallon total. These additional nacelle tanks would make approximately 153 gallons, it appears.
Does anyone have flight ops experience with these aux tanks?
