Now here's an answer to the fuel problem

The Peel P50, the world’s smallest road-legal car, is a little gem. (And if you ever watch BBC’s “Top Gear” on BBC America, it was the hero of a great show where Jeremy Clarkson dragged and drove it around the BBC HQ’s offices — it even fitted in the elevator!)
Its most recent appearance was at the funeral of its inventor, Cyril Cannell. The Peel P50 was the first in a series of experimental microcars built in the 1960s at his fibreglass firm Peel Engineering Company.
Seventy P50s were produced between 1963 and 1964, not many remain, but this one was bought by Peel’s Manx Transport Heritage Museum after a public appeal in 2005 and it stood guard as its creator was laid to rest.
