Liquid filled vs. non liquid filled guages
I have had problems in the past with non liquid filled guages due to the vibration. Waterproofing is also a challenge. For my SHO conversion, i bought 2 Autometer Z series guages.
P# 2612 fuel pressure
P# 2614 boost
Knowing ahead here, that the E1 and the H1 SC they vibrate. Last year, i ran an Autometer non liquid filled fuel pressure guage and it didnt last 3 weeks. The vibration from the compression/triple pipes/timing combo killed it. When i removed the guage, it showed 28 psi fuel pressure unhooked! We have a Summit Racing close to us and i called them, looking for a 2 1/16" liquid filled boost and fuel pressure guage and they could not find one, even through other brands.
Here is the closest thing they came up with:
Autometer 2 1/16" digital:
P# 6359 boost
P# 6363 fuel pressure
Total $382.90 plus tax!
Maybe someone can enlighten me here.
Are the digital guages accurate?
easy to read in the sun?
The last thing i want is another guage failure.

I have liquid filled on the GPR and digital on the SHO by far i like the liquid filled they are very accurate, The digital tend to sway back and forth about a pound.

Thanks Jim. Hard to find 2 1/16" in liquid filled, but the 2 5/8" are easier i believe. Not sure the guy at Summit Racing found what i was looking for.
