Car Forum / Dodge / Dodge Trucks / October 2006Fuel PSI or Rail Pressure gauge
I am contemplating having a recommended mechanic put gauges in my truck (2004 Ram 2500, CTD (305/555), 4x4). I mentioned to him that I wanted 1) Fuel Pressure, 2) Tranny Temp and 3) Pryometer. He mentioned that a Rail Pressure gauge would be a better choice than a fuel pressure gauge since the lift pump issue was resolved after 2002. After the semi-heated discussion between Nate and Max, I am left wondering exactly what set of "facts" to believe. So, I'll throw it out there for the pros in a.a.d.t. to opine about. Should I go with a fuel psi gauge or a rail pressure gauge? Craig C.

Mike when did they move the pump to the tank? I'd be watching the fuel pressure before it gets to the rail . I've only seen or heard of a couple of problems with the in tank pump also haven't heard of many problems now with the earlier lift pumps now that they've been improved.

Just out of curiosity ... why would one want to monitor boost? Craig C. SignatureFacts [fakts] -noun: The pesky things that get in the way of religious doctrine. > Should I go with a fuel psi gauge or a rail pressure gauge? Let's take a step back... what's the reason for gauges? Are you modifying the truck, keeping it stock but planning on towing heavy, or just want to know what's going on under the hood? > > Should I go with a fuel psi gauge or a rail pressure gauge? > > Let's take a step back... what's the reason for gauges? Are you > modifying the truck, keeping it stock but planning on towing heavy, > or just want to know what's going on under the hood? I plan to keep everything stock. I do pull lake toys, although what I currently pull is not heavy (< 5000 lbs). A travel trailer is in the future, but I have no idea what I want or how much it will weigh. Really, my reason in wanting the gauges is simply to monitor "things" before they become huge issues. i.e. the fuel pressure discussion of recent and past made me believe that I needed to monitor it so that I can head off any major headaches (replacement of the injector pump). Did I misunderstand? My truck does *not* have the lift pump issues? Tranny temp and pyro are really for towing, I know. Those will be used more and more as time goes on. I guess I assumed, perhaps ignorantly, that a fuel pressure gauge is necessary. At this point, assuming my truck does not have lift pump problems, I'm really just looking to "fill" the third gauge hole. 1) Tranny Temp, 2) Pyro and 3) ??. Craig C.

No you didn't. But the failures of lift pumps on you truck are pretty much a non issue. But, a fuel gauge is one way to tell if the pump is going out or if your filter is dirty. > My truck does *not* have the lift pump issues? > [quoted text clipped - 3 lines] > I guess I assumed, perhaps ignorantly, that a fuel pressure gauge is > necessary.

Imho I'd go with the fuel pressure and a boost gauge if you can. If not the fuel pressure. Roy > Craig C. Bump. Tom, or anyone else ... Rail pressure gives me more useful/practical information for a stock setup? Or ... ? Again, just looking to fill the 3rd gauge hole with the most practical gauge ... Mike mentioned a turbo boost gauge, but I can't think of why that is something that should be watched ... like a pyro and tranny temp.

Craig: A boost gauge is useful to help drive for fuel economy and also to monitor the turbo's output. If you can drive and keep your boost pressure <10psi you will be driving for max economy. Should your boost plumbing or intercooler develop a leak, the boost gauge will show a loss of pressure compared to what the nomral boost pressure should be. The boost gauge would be more useful than a fuel pressure gauge IMHO... different strokes I guess......

All this time I thought a boost gauge was simply so one could watch the needle go back and forth ... :-) Craig C. > Makes sense. Thanks Mike.

I'm up to 60 :) >> Makes sense. Thanks Mike.

I'm up to 60 :) Haven't seen any pic's of your toy recently. Please post a couple.

If you can drive and keep your boost pressure <10psi [quoted text clipped - 3 lines] > be more useful than a fuel pressure gauge IMHO... different strokes I > guess...... You know, after thinking about it, you bring up a good point. I have noticed over the past year a strange noise that comes from what I *think* is my turbo. It use to only do it when it was cold outside, but now it does it all of the time. When I accelerate faster than usual, RPM's at say 2500+, the turbo stops whining and starts whistling. When I say whistle ... I mean it sounds like a human whistling. Other than the possibility of a happy person stuck under my hood, could I have a pin hole somewhere that cuases this? Or ... is this simply a "normal" sound?

Or ... is this simply a "normal" sound? Could be normal but you probably have a loose clamp. Roy > Craig C. > Could be normal but you probably have a loose clamp. Something that would be a little easier to detect if he had a boost gauge! :^) |
