Yeah,

I just got a reply back from their technical dept saying this:

With any Dodge Diesel, we do require the snubber valve to be used.


Thank you

It doesn't indicate this on the "gauge" page of their website, otherwise I would have ordered it... so now I'm out the shipping charge to get it separately. They do however tell you in their Installation instructions that come with the gauge.

Yes get the snubbed or use a needle valve as the pulses from the lift pump will burn out the electrical gauge real fast. Some have had a gauge go dead in as little as a week from not running a snubber/needle valve.

If you have a mechanical gauge it won't ruin anything but it's real annoying to read. Air in the line helps as well. It helps dampen the pulses

Ok, I'll be the devil's advocate.

Please explain how the absence of fuel pressure gauge leads to ip or whatever malfunction. If the pressure is too low, you'll notice there's something wrong with the engine. I've run my 1st gen at 0 psi for several hundred miles over steep grades when the lift pump quit. It didn't break anything, it's been 3000 miles ago.

And I don't use a snubber with my digital glowshift, the instruction that came with it did not even suggest a snubber. It works just fine, if only all the contacts would just stay put. Had it for more than 2 years. Now that they sell a snubber, they say it's required? Please . . .

If there's anything wrong with the glowshift, it's the connector contacts - they become erratic after a while. And of course it's hard to read in bright sunlight.

Pressure gauge can indicate problems like fuel or air leaks or a pump on it's way out. It's not wise run that low of a psi. Diesel is what lubricates pump internals. I think that is why my pump seized.

The local pump shop does claim that a VE will pull it's own fuel and really shouldn't ever hurt itself. They also added that is without a lift pump in the way to keep it from pulling it's own fuel. They can fail open or closed and if they are working but not well enough then the Ip has difficulty pulling fuel past the lift pump.

Rick 12v CTD

The ve will pull it's own fuel, but I'm guessing only to a certain point where the power level exceeds the pumps ability to pull. I would never run it down to 0 psi. If you choose to and nothing has broken, all the power to you. But just because it hasn't failed for you, doesn't mean it won't and hasn't for others.

And on the snubber thing, do a search on this, or any diesel forum on electric gauges failing for lack of a snubber. It's a fact. Maybe glowshift makes a product that is superior, I don't know. I would snub any electric gauge that has an electric needle sweep. If it was digital, maybe not but if for no other reason do it for the sake of running a gauge that's easier to read and isn't so erratic.

Thiss

With the 3 and 1 I need the snubber, but do I need anything else? Glow shift support said they do not have banjo bolts or the like, do I need to source this?

93-12Smoke

You can get that from Genos Garage

NJTman

Genos has the combination snubber / banjo

No that is just the banjo or at least that's all they sent me.

ClassA4x4

That says 1.5 thread. I know my glowshift is plugged into a 1/8 npt banjo which is also plugged into a 1/8 npt port on the intake. Maybe a 1.5 is close enough to 1/8?

93-12Smoke

That banjo is metric on the end that goes in the head then 1/8npt on the sending unit end.

I just got my gauge kit, and man that was fast shipping..


Anyone have any tips for running the wiring ? I'd like to "disappear" but depending on where I put the gauge, it will ultimately show. I'll buy a loom for it, but was looking for ideas on how to make it look as professionally installed as possible. Drill a hole in the dash, if I'm sticking it up top? I cant really fit it well on my steering column, as I already have a tach / pod there


Thanks !

Pillar mount? I installed mine on the column since i already had other gauges on the pillar.

NJTman

The 3 in 1 gauge is a "60 mm" unit. The pillar mounts are 52mm I believe.

Either way, where do you run your wires ? How does it look ?

93-12Smoke

Drilled holes in the factory trim so the wires come out of it and into the pillar pod. It hides the hoes. If i would just order the paint to the pod to match the trim it would look clean.
