It's actually 7 3/4 when you include the fill tube. I think the 70-minute fuel duration holds up well regardless.

Bob, we have been figuring 9 minutes to a gallon on our SRf3. So is everyone racing an SFR3 getting 10 minutes to a gallon like the older SRF ?

"Your mileage will vary" seems to apply with SRF3. My GEN2 got a fairly good average 10 minutes to the gallon (more at Lime Rock, less at The Glen). I've heard of GEN3's getting better than 10 minutes to the gallon. Mine came in around nine-ish.

The good news is that the fuel pump pickup sucks it all out, right to the bottom. (Unlike the majority of GEN2's with the external pump and box.)

Bob, Last race JD stated the car felt out of fuel on the cool off lap. Well... during setup for next race, we pulled fuel NO fuel. Yikes just bubbled in the clear hose!
