Nice little gauge. Seems to read pretty accurate. - accurate enough for an inline fuel gauge. Looks good, too. Quality is surprisingly good. Good value. 1/4 the price of AutoMeter.

After being attached to the Fitech EFI fuel inlet for 2 months, it still reads within 1 or 2 psi @ 58 psi.UPDATE 3/9/19The gauge has been attached right at the EFI inlet since my original purchase and is still working perfectly.UPDATE 5/10/23Still going strong after 5 years and 23,000 miles under the hood of a '67 Firebird.UPDATE 10/15/246 years and still good. Going to order another one of these for a different vehicle.I tried a different (cheaper) brand that lasted 2 days before it developed a major leak. Lesson learned.

Went bad and sprung a leak within 3 days of use. Unfortunately, it's outside of the return window because of waiting for other parts to finish getting vehicle running. Lucky we didn't burn the truck down and it happened while fine tuning the new fuel injection. I bet it has 10 start and runs for a total of about 2 hours.
