LP Idiot Light or Press. Gauge?
 

At 61k I am really worried about my LP. I don't have gauges and found a place on the east coast that sells a kit with a bajo fitting, pressure sending unit and light that will come on if the feed pressure to the VP-44 falls low for $50.00. Obviously a gauge is better but I have only found the type that would send fuel into the cab. Does anyone have advice on either approach? Or better yet a link to a dealer. I can't afford full gauges (and have no mods yet). I don't want my LP to be silently killing the IP and my 70K powertrain go out. :o [verymad] [yuk]

TIA!

:cool:

gauge!

if fuel in the cab is a concern, mount it outside? i have fuel running to the inside and am not concerned, but to each their own.

I have an electric Autometer FP gauge.

Gauge
 

No Choice but a Gauge,, I paid $75.00 for a gauge Complete,, Good Investment.

Whaaaaaaaaaaaaaat???? I will take one! Can you give a number? Also was it a kit??? I plan on getting the pillar here:

Your welcome

If you buy the gauge from Geno's they will throw in an in dash mounting kit for free. It mounts in the cubby hole by the radio. I think the kit is $7.50 to buy alone.

Yeah, I wouldn't waste money on a idiot light. You need to know what the pressure is running. Look around at the vendors under the links tab.

Mr Gilles, they are fine inside as long as they don't do like my 2 Isspro's did, start leaking. They leaked diesel all in my truck along the floor,dash, & under dash areas. I do not think it is a good idea to have mechanical fuel guages in the truck. I think Geno's sells a Westach(spelling) electric guage that works very well. It is important to mount the sending unit on the fender or somewhere it won't be vibrated to death. Don't mount it directly through one of the banjo holes. It will just get shook to death.

I have fixed numerous leaky fp guages from 4 different mfr's and EVERY time it was because the ferrule was not properly installed....10 minute fix. FWIW if you run a snubber valve you can shut it off in the event of serious failure....which I have yet to see.


Oh I agree guage, mechanical guage, all the way

Despite the resounding "mechanical only" philosophy on this forum, I went electric with Dakota Digital (previous drag racing experiences and tech inspections said "no fuel in passenger compartment"). Nice gauges, and they match the display in the dash/radio. Their website is http://www.dakotadigital.com

High Country, in both of my IssPros, the seals in the guages failed. It had nothing to do with the line or anything. It was guage failure. I like mechanical guages when they are practical, but for any kind of fuel pressureguage, I think an electric or digital is just as good & accurate, with less head aches. It is just hard to teach mechanical dogs electrical tricks. Right On!! [laugh]

Bighead, there are no seals inside mechanical pressure guages. Inside a mechanical pressure guage is a device called a Bourdon Tube and it expands/coontract with increasing/decreasing pressure and is connected to the indicator that move up/down the dial.

Its hard to belive you had 2 bourdon tubes fail with the small pressures produced by the fuel systems on these trucks. What ranges were these guages? 0-15 psi?

I also find it hard to believe. I've used hundreds of pressure gauges in all kinds of different applications, up to 10,000 psi and have never had one leak internally in forty plus years.

My observation has been the same as High Country's, 100% of the fuel leaks I've dealt with were due to over tightening of compression fittings distorting the ferrule so it leaks.

I purchased a ISSPRO fuel pressure kit from Genos Garage - It came with a
2" Isspro 30psi fuel pressure gauge (includes isolator and 8' tubing kit)
The isolator with keep the fuel outside the cab. Just installed it but it seems to work well. Just another option.
