Technical Low Fuel Pressure Gauge

The comparison should be between the Dicks 0-5 and the 0-15 posted earlier in this thread, you'll find that makes more sense.

 

How about showing us the pictures?

 

Marshall gauge for me. Have used both filled and unfilled.

 

I have what the OP was asking for but he never pm'd me so maybe changed his mind.

 

I’m sorry Seb, I somehow missed your earlier post. I will pm you now.

 

Did you end up with a gauge? Just found one here, but Seb was 1st.

 

I've been using the old air or oil pressure gauges they work well and check pretty accurate

 

Here's an idea. Run one initially, 1st cpl weeks maybe. Now take it off, give the innards a drop of 3 in 1 oil, seal it up and put it away. Fuel pressure is a set and forget. If you have to up and down all the time there's a problem. Now it's a tool and not something that may vibe apart and become wrong, or worse, leak with potentially firey consequence. Once you've sorted that out you can easily discern stuck floats and such that may bring issues.

 

why would a 0 to 100# gauge be less acurate than a 0 to5# gauge? I see no difference.

 

Any instrument that has a larger scale is inherently going to have more error in the measurements at certain points in the scale.

A 0-5 gauge also gives much better resolution when reading say 3.5 psi than a 0-100 gauge, because it's effectively zoomed in.

 

I have found that replacing the liquid in liquid filled gauges with DOT 5 brake fluid results in less needle vibration.
