Bucking and snorting, a Thunderbird rolled up the apron of the Model
Garage, stalled, and slid back a trifle. Stan Hicks, Gus’s assistant,
hurried up to it. “Oh, it’s Mr.
Kenquist,” he said. “See you got another car.”
lantern-jawed driver angled himself out past the windshield corner. “Need a
new fuel pump quick. Got one?”
“Yessir. Are you
sure it’s pump trouble, though? I could check—“
“No time. I know
what I want.”
appealingly at Gus, who had come out to read the pump registers.

why not let us make sure before you pay for a new pump?”
“Give you five
minutes,” agreed Kenquist grudgingly. “No more.”
the pump line at the carburetor, held a can under it, and briefly cranked
over the engine. A scant trickle of gas came out. “Sure isn’t
pumping,” he said. “Could be a plugged gas line.”
“Sooner you put in a fuel pump, sooner I can go.”
began to loosen the coupling between pump and tank. Then, abruptly, it
stopped. Not a drop of gas appeared at the open coupling.
Thoughtfully Stan retightened it.
“Well, what now?”
asked Kenquist. “Would you try your engine again.”
scowling, Kenquist got in the car and turned the starter on briefly—without
result. “Told you I need a new pump.” “Try a bit longer,” urged
Stan. Angrily, Kenquist resumed cranking. Suddenly the engine fired
up. It ran smoothly, but Kenquist got out no more pleased than before.
“It ran this
morning. It runs now. That’s no proof it will keep going.”
“Don’t suppose it
will,” returned Stan. “Let’s see.” He held the throttle rod at a fast
run. The engine first took it well, then began to run rough.

“Maybe that you
need a gas cap,” remarked Stan. “Did you change it?”
“It fell off on a
trip,” said Kenquist, following Stan to the back of the car. “Of
course I got a new one.”
Quietly Stan began
to twist off the tank cap. As it came free, there was a whoosh of inrushing
“They sold you an
un-vented cap,” explained Stan, “one for a car that has a separate vent
tube. This cap has no hole to let air in as gas is pumped out. When
the vacuum inside is the same as your fuel pump’s pull, you get no gas.
“What! It’s acted
up several times, but the engine always started again.”
“Sure. Air slowly
leaks in. You drive a while, and then the vacuum builds up. When I
disconnected the tank line up front, it drew in air. Then the pump could
deliver gas again.”
“Hmmph. Got the
right cap?” asked Kenquist. “I’ll demand a refund on this one.”
Grinning a bit smugly, Stan returned to the shop as Kenquist drove off.
“Isn’t he the one
who wouldn’t change his engine oil?” asked Gus.
“Yeah. He swapped
cars but not dispositions. Sour as ever. All set to buy a fuel pump, but
not a kind word when I fix him up for the price of a gas cap.”
“I heard it all,”
Gus admitted. “Good job. You didn’t even waste time, as I would have,
doing the one thing that wasn’t necessary.”
“What’s that you’d
leave have done?”
“Checked the gas
gauge first,” answered Gus with a grin. “To make sure there was gas to
Darkness lay on the
suburban countryside as Gus drove back from a road call late afternoon.
Rounding a curve, he came on a pair of tail lights stopped ahead. Beside
them a tall man waved an urgent signal. Coming to a halt, Gus
recognized both the sports sedan and its gaunt owner. “Trouble again, Mr.
“Told your young
smart aleck I needed a new fuel pump,” snapped the black-browed man.
“It used to start up again in a while after it quit. Now it won’t even do

along,” said Gus, peering at the dash. “Got plenty of gas, I see. Is this

trouble light and we’ll see what can be done.” “No you don’t,” snapped
Kenquist. “Got a dinner engagement—business dinner. No time to fool
around. You tow me back, keep the car overnight. See you in the morning.”
“If that’s how you want it,” agreed Gus. “But I might be able to fix it
right here—save you a tow charge.”
Lantern jaw set,
Kenquist shook his head. Gus backed the wrecker into position for the tow,
and hauled the Thunderbird in. But neither he nor Stan got around to
checking it then.
“Plenty of gas on
the gauge,” Stan reported the next morning. “But none pumps through. Sure
is no air block now. Nothing’s plugged either. I put air on the tank line,
and could hear it whistle way back in the tank.”

him, then burst into a laugh. “Oh, no! You mean the gauge is stuck and old
beetle-brows simply ran out of gas?”

shadow on the shop floor. “I filled the tank and drove only 150 miles.”
“Suppose we put in
one gallon and try the engine?” suggested Gus.
grumbled Kenquist. “Then install a new fuel pump.”
From a can, Stan
poured one gallon into the tank. After moderate cranking, the engine took
hold with a deep roar.
“Doesn’t seem like
a bad fuel pump,” remarked Gus. “It’s your gas gauge.”
“Fill the tank,”
ordered the lantern-jawed man. “It holds 20 gallons, but you won’t get in

up and out of the filler neck, splattering him before he could shut it off.
The tank was brim full. Without a word Kenquist returned to the shop.
“She took 101/2
gallons, Boss,” reported Stan a minute later. “Full up.”
Gus frowned. “But
that model does have a 20-gallon tank—and the air didn’t gurgle. You’d
better put it on the lift.”
Kenquist stood by as Stan raised the car. Gus walked under it with a
light. The tank showed no trace of leakage. But one side of it was caved

ducked under the lift. “What is it?”
Gus flashed the
light on the collapsed tank. “With that unvented cap, the fuel pump created
quite a vacuum in the tank. That let outside air pressure shove in this
wall, and that’s why the tank holds only 11 gallon.”
“Not enough. Going
to be a nuisance on long trips,” said Kenquist.
“Maybe we can pull
it out,” mused Gus.
“Shall I hook an
air hose to it, Boss?” asked Stan.
“There’s a tool
might do it faster,” mused Gus. “Go get it, Stan. It’s in the store room.”

into frowning silence. In a moment Stan was back with a common “plumber’s
helper”—a big rubber suction cup on a stick.
Wiping the tank
clean, Gus applied a smear of grease around the suction cups, seated it
firmly in the center of the tank, and gave it a sharp pull. With a loud
click the dent snapped out.
“There’s your 20
gallons back,” said Gus, wiping the grease off. “That dent is probably what
jammed your tank float. I think your gas gauge will tell the truth from now
quivered in a ghost of a smile. “Hard thing to get at—the truth—isn’t it,
Mr. Wilson?” he grunted. “Would have been easier for you to sell me a
new fuel pump…But it wouldn’t have solved my problem.”
“Not only that,”
Gus grinned. “But now I’ve got a full-size tank to fill up when you stop in
for gas. I’d rather sell 20 gallons than 10, any day.”
