Autometer electronic fuel gauge

[Vaman]

Well I finally got my fuel gauge and installed it on the outlet test port of the fuel filter assembly. Something isn't right. I'm only seeing about 2 to 3 pounds when the lift pump first fires up (pre-start) and just a little over a pound running down the road. Anyone else using this gauge? Any suggestions? I'll probably run to the hardware store shortly and slap a mechanical gauge on it to compare the two. Thanks in advance.

Ten bucks says your lift pump is shot...

I have that guage in my truck and see 11-12psi on startup and around 9-10psi goin' down the road. Never gotten lower than 5psi at wide open for 30-45 second burst.

Vaman, where did you buy your gauge from and did you need any additional parts? Also did you use the center-most port off the fuel filter housing?

Thanks!

I got it from Summit and no additional parts were needed. The transducer/sender comes with an 1/8 pipe connection which is very convenient if you have the fuel filter assembly with the test ports. I'm not real happy right now... I've either got a bad pressure gauge or a bad lift pump.

Sorry to hear about the low pressure readings. Same on both ports? Any chance your fuel filter's dirty? Hope it's an easy fix Vaman.

So far I've just checked the outlet port so it's possible I'm getting an excessive drop across the filter. I checked the service manual and the specs look like a minumum of 10 pounds inlet and a max 5 pound filter drop. I'll get a test gauge and do a cross check. I haven't had any performance problems so if it turns out that the lift pump is dying, I'd say everyone out there should probably have a fuel pressure gauge (probably a good idea regardless). Anyhow, I'll post the results when I get an answer. Is anyone else getting tired of fuel system posts on this forum? #ad

YES!!!! I think everyone is POed (or should be) about the cheap $h*t Carter electric fuel pumps on the 24v CTDs as well as the stupid factory mounting location of said pumps. #ad
