I thought I would be "Mister Smarty Pants" and read up on the engine mount 1.5" fuel pressure gauges and try to find an accurate quality unit for carb applications. Well, I found a 0-15 psi MOROSO type to place in-line a few inches from the carb. The first one worked for about 40 minutes and then failed to indicate correct pressure (stuck at 2 psi permanently).
I confimed I still have a stable 6 psi with other test gauges and confirmed my filter is OK with no trash in the line. The MOROSO unit seemed nice, it used an internal damping feature without liquid fill to keep the needle steady (yeah now its steady at 2 psi !
.
Called the manufacturer and you guessed it, 90 day warranty sorry bud !
Then, I put in an even cheaper unit but its needle jumps +/-2 psi during operation from pressure pulses, which is really useless. I dont want to use a liquid filled gauge since the fill fluid temp will vary the indicated pressure on the gauge, unless someone knows of a good one.
My question is who makes a quality 1.5" fuel pressure gauge that is engineered to "fit and forget", this is proving harder to find than I imagined. Do I have to source an expensive industrial gauge ?
Tell me what fuel pressure gauge you have used with years (not minutes) of good performance. I dont mind spending the money if its a lifetime quality gauge.
Thanks for your replies.
