Marshall Instruments LB00100 Fuel Pressure Gauge

Seem to temperature sensitive

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.

Great fuel psi gauge for under the hood. No issues and is quality.

Made in USA!!!!! Quality product for a great price. Used this on my 4.8 LS and very accurate

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.
