Sorry about the blur, the camera doesn't like to capture light very well.

Yes sir! I did the rest of the wiring earlier this afternoon when it was 28 out. I just went out and mounted the sender to the fuel rail before I shot those pics. It just started snowing as you can see.

So far it does what it is supposed to.

I have it set to alert me of fuel pressure goes below 23.5psi or over 62.5psi (I'm gonna lower that one I think). It also dims when the parking lights or headlights are on. And the switch I installed on the gauge pod works good so that I can turn the gauge off if it is aggravating me. :D

I like it!

[OT] This is one of those posts I had to reload about 30 times to reply - I know using old Netscape - AHHH I hate Netscape but I hate IE MORE [/rant]

Anyway, I had a Sun Tach on my Lemans years ago that was just too bright, and picked a resistor to put in line with the dimmer input. Got it so it was just perfect with the rest of the guages. Maybe that would help? You may be able to hang a pot on the dimmer feed and adjust the brightness for that one guage the way you like as well. I could calc what size pot to buy (like $1.00) if I knew the voltage and current on the dimmer line to the gauge (with gauge hooked) at each end of travel of the stock dimmer pot.

PeteL,

Thanks, but it already does dim. It is a dim/no-dim though, no variable. There is a terminal on the back of the gauge that you attach a 12V feed to. The feed is spliced into a brown wire under the dash which is the parking light circuit. It is active whenever the parking lights on. :)

Dakota digital sells a dimmer that is supposed to work, but that is one more thing to have to mount somewhere.

Yup, that fancy **** is sitting on a $0.35 pot. You could hide anywhere and set the way you like. Bet the main dimmer would run the lot, but not sure. LED will dim to an extent!

Also those fancy smancy new GE panels will dim, I took my clock radio apart and dropped the brightness about 50% and it's clear as a bell. Somebody want's to save $0.05 on a resistor!

EDIT: OK, read that again, is there a two wire hook up for that control on the guage? That control is an X$ **** on a standard pot. All we need to know is the resistance across the terminals on that pot (end terminals - one of which is unused)and if it's a linear taper or log taper (if'n we want to be fancy). That mod will cost under a dollar easy.

I like how it matches the rest of your digital gauges. Very cool!

Oh, how buried in snow are you? It's coming down here BIGTIME.

About 1/3" right now, it started only about an hour ago.

Scorp

What does the setup look like at the fuel rail ?

Can we get some pics when you get a chance ?

Sure no problem. Might have to wait till morning. There is too much metal in the area and the flash will wash out the detail.

I made a big mistake in my last post, the sender is 1/8" NPT, not 1/4" NPT like I thought. I somehow got confused early on and ran with it.

From the fuel rail is a female to female -4AN swivel. Into that goes a 90 degree -4AN to 1/8" NPT fitting. On that is a brass female to female 1/8" NPT fitting, which is joined to the sender. The sender is sort of sitting right in front of the #2 distributor terminal.

It is empty. :) Far down the road a nitrous pressure gauge, but perhaps a tranny temp gauge for now.

I have the Harlan unit, and am told it will blind me at eye level. :) I think that baby is going into the air vents.

Hmm....

Gauge: $80.00
Sender: $24.00
Gauge Pod: $25.00
Swivel Coupling: $7.00
Elbow Convertor: $13.00
Brass Coupling: $1.50
Switches (Optional): $5.00

So about $155 give or take a few. I already had wire and terminals for everything.

Now that I know how and where everything should be wired and hooked up, it would probably take me about 2 hours at the most to install one of these from start to finish. That includes drilling the gauge pod for the switches, and soldering everything inside it.

Fuel pressure gauge on a stock L98. Pretty cool there Riceboy. :D :D :D

BTW, I might need to buy your spare Super Ram gasket kit, I may bolt the heads and intake on the 383 Monday if I can't get the lift to do the Dana44/dual exhaust swap.
