Thank you all for the advice. The eBay number takes one to a 4.4f unit.
Apparently I need 1f. I gather that will create 4.4 times less damping.
Makes sense. Still be a bit slow I'd think.
The thing costs pennies. I'll give it a shot.

Here are two thoughts, Simon,

First, you most likely won't be consuming petrol so fast that a five minute
lag in display would cause trouble.

Second, you don't tell us what size cap you got, 1 farad?  5 farads?
or what?  If you got one that was half the size, say 1 farad instead of 2,
the gauge should respond twice as fast, or half as slow -- take your pick.
