Unleash Optimal Performance with Marshall Instruments LB00100 Fuel Pressure Gauge Review

Looking for a reliable car pressure gauge that delivers accurate readings every time? Look no further than this Automotive pressure gauge. It's easy to use and provides clear, precise readings that make it easy to monitor your car's performance. The gauge is well-made and durable, so you can trust it to last for years to come. The only downside is that it may be too large for some users, making it hard to store in smaller vehicles.

I installed it on a Caterpillar engine to check the fuel pressure at the injection pump. Fits perfectly and always gives me an accurate reading.

After being hooked up to a Fitech EFI fuel inlet for 2 months it still reads within 1 or 2psi at 58psi. UPDATE 3/9/19 The gauge has been attached directly to the EFI intake since my original purchase and it still works great.
