LP - What are the odds?

LP - What are the odds?
I recently purchased a used '01 CTD Ram 2500 w/65,000 miles on it. The original owner said he never had a LP or VP replaced on the pump. Only one upgrade of something he couldn't remember under warranty. I don't have a fuel pressure gauge on the truck now but plan on putting one on in the next month. The truck drives and runs great and there are no codes. What are the odds that the LP is still working fine? Reading all the posts here makes it sound like they fail pretty regularly.

i will be on my 3rd in 10months, i got some great odds if its 1 in 10G.
I'd get a FP gauge only way to tell its not an investment its a must have like a gas gauge

Hmm.....I'm not so sure about those 1 in 10,000 odds. Regardless of how the truck runs and the absence of codes, you should test the LP pressure asap.....The truck can run fine and not set any codes even with 0 psi at the LP.

BUT, that said I still check my LP pressure at each oil change with a portable Briar Hopper FP gauge.

Main point is this... you know that the pumps in the year model of your truck has a high probability of going out, I'd make sure it's not already out and check often until you get a permanent guage mounted...may save you the $$ in the long run...

Fuel pressure gauges are not that expensive, and it is necessary to monitor the LP pressures. Consider it a cost of buying the truck, and get one in. If you can do it yourself you save some money, if not pay to have it installed. It will quite possibly save you a lot of money in the long run.

My 02 has almost 40,000 miles. The origional lift pump started going out at 38,500, the one I replaced it with went bad amost out of the box. The 2nd replacement seems to be fine in the 1500 miles its seen. If I was buying a used 2nd gen truck, i'd find a way to check the fuel pressure before I even bought the truck.

What are the odds? With a 100% failure rate within 100,000 chances are very good your pump is dead and you are running off your IP which will cost you $1,200 easy.
Order a FP guage tonight.

Ok.....I am scared now. Just ordered a FP gauge from diesel manor along with a boost gauge and A-pillar pod set up. Guess we'll see what she reads once I get it hooked up. How long can an IP last with a dead LP?
Per all the other posts I have read here I plan on just using a needle valve w/o the isolator. Is that pretty much what most of you are all running? It sounds like the isolators don't hold up anyway and you end up with fuel in the cab and you don't know it.

GUESS IT HAS TO BE THE GAUGE. I HAVE A MECANICAL GAUGE THAT WAS ORIGINALLY HOOKED UP THRU AN "ISOLATER" (I THINK IT'S CALLED) . WHEN I FIRST TOOK IT OUT OF THE LOOP I HAD NO FLUTTER FOR MONTHS.
DO I HAVE TO PUT AN ISOLATER BACK IN SYSTEM TO QUIET THE GAUGE DOWN OR SHOULD I GO ELECTRIC ?

Mine was smooth for about 15 minutes after changing my lift pump 9/04, been fluttering ever since & I tolerate it . You can install a needle valve on the guage line to dampen the pulses.
