Mityvac

PRODUCT DESCRIPTION:

FST Pro

The reviewer finds this product essential in
testing returnless fuel delivery systems on
model year 2000 and newer vehicles.
by Sara Scullin, Scott Brown

The Mityvac FST Pro, No. MV5545, helps users diagnose
and pinpoint common fuel system failures, including a
failing fuel pump, faulty pressure regulator, blocked filters, pinched fuel line, contaminated fuel, and fuel tank
vortex. The tester measures fuel system pressure and
flow to accurately pinpoint fuel system failures, and can
help save troubleshooting time by diagnosing a bad fuel
pump and other related drivability problems. The patented
system simulates extreme driving conditions in the shop
to provide an accurate diagnosis. The tool is capable of
testing both return and returnless fuel systems, including
electronic control, and provides clear visualization of fuel
to detect impurities and air bubbles. The kit includes a 3.5"
high-pressure gauge with rubber boot, push-button relief
valve, and hanging hook; 4' long pressure test hose; inline
pressure test hose with 1/4-turn valve; 37 adapters for connecting to most U.S., European, and Asian manufactured
automobiles; a pressure relief hose; custom molded case;
and an operator's manual.

THE REVIEW:

cott Brown, owner of Connie
& Dick's Service Center in
Claremont, California, says
he's been testing fuel delivery systems
for many years using a flow meter -
a test, he's found, many shops do not
bother to perform. "Since most of the
vehicles we see today are returnless,
the [Mityvac FST Pro - Fuel System
Tester, No. MV5545,] makes it quick and
easy to make a professional assessment
as to the performance of the fuel delivery system," Brown says.
The Mityvac FST Pro arrived at
Brown's California shop packaged with
a carry toolbox that can house the entire
kit. Although for quick access, Brown
recommends hanging the assembled unit
from a point approximately 6.5' in the
air, to ensure that the lines are straight,
which makes the unit very accessible for
its next use. Brown noted that the prod-

uct included many of the popular quick
connect fittings required for technicians
to quickly access the fuel delivery system. Additionally, the tool had a bypass
circuit so technicians could measure
the fuel pressure and flow dynamically.
Brown says after just a few connections,
and a quick read of the manual, he was
up and running within 30 minutes.
"Once you understand what testing
you're about to perform, and how to
make a connection to the vehicle, usage
is fairly straightforward." He adds, the
included manual has "a lot of great information," including a fuel flow specifications table for various engine sizes, and
maximum rpm-levels which provide the
service technician with valuable reference data. Brown put the fuel tester to
use on vehicles with drivability related
issues that required him to validate the
fuel pump/delivery system. In using the

Mityvac FST Pro - Fuel System Tester,
No. MV5545, he quickly appreciated the
unit's rugged build, its quality connections, gauges, the gauge bleed-off valve,
and a bypass valve which he said was
"essential in testing the performance of
the returnless fuel delivery system found
on most vehicles built since 2000." In
future iterations of the tool, he noted he
would like to see longer service hoses,
which would make for an easier time
connecting to the fuel system from
under the vehicle. Thanks to its aboveaverage build quality and ease of use,
Brown finds the Mityvac FST Pro - Fuel
System Tester, No. MV5545, helps him
to quickly and easily perform essential
checks on fuel delivery systems present
on today's vehicles.
