Hook up Fuel Pressure Gauge
#16
suggestions on a nice [electrical] fuel gauge for $40?
I just bought a $20 mechanical gauge from harbor freight (more or less as a temp permenant to keep tabs on my pressure regulator modification) but have yet to install it. the plumbing parts cost close to $40.... so i'm in $60 total. I might as well go electric and keep the sucker perm. monuted in the cab along side my other gauges.

I used a brass compression fitting to replace the Shrader valve on the fuel bowl. From this fitting, I installed a 1/16" nylon hose normally used for oil pressure gauges. I ran the hose to the firewall, where I installed an L-shaped bracket to hold a needle valve to eliminate the pulsations of the factory fuel pump. The hose provides fuel under pressure to the needle valve. On the other side of the needle valve I installed an electric fuel pressure gauge sending unit. From the sender, electric wires provide fuel pressure reading to a gauge in the cabin.
After installing the setup, I closed-off the needle valve and started the engine. Then, I very slowly opened the valve to the point where the fuel pressure is steady and void of the hammer-effect pulsations so common with a mechanical fuel pump like the OBS's.
A specialized "snubber" device also can be used in place of the needle valve to eliminate the fuel pressure pulsations. Although snubber devices are not adjustable, some folks have luck using them.
While the fuel pressure gauge can be used without a needle valve or snubber, doing so usually makes the gauge very difficult to read due to the rapid needle fluctuations, and often the life of the gauge is significantly shortened by the stress of the hammer effects.
Of course, folks who install an electric fuel pump don't have to worry about fuel pressure pulsations, because electric pumps generally don't produce a "hammer" effect,
