Review on High-Performance Marshall Instruments LBB00015 Fuel Pressure Gauge in Sleek Black Design by Alex Taylor

Good buy, there are high and low blocks on the Aeromotive EFI for the carburetor duel pressure regulator (the high level is under the braided cords in the picture) and they are great at that, no. It has not leaked at all and looks amazing. Money saved, but the quality sensor has remained. They fluctuate after riding due to fluid expansion/contraction and high engine compartment heat. It is equipped with a manual pressure release if you need to take measurements after launch. Personally, I make my adjustments after it warms up to operating temperature. I will bleed the pressure if there is one and then adjust the fuel pressure. Some pressure adjustments are usually required after the initial setup unless there is a mechanical cause like a new fuel pump or similar. I just check mine regularly to make sure everything is in good condition. I still haven't spilled a drop of liquid, I'm very happy with them and I recommend them to everyone.
