01 Hard to start "at times"

[Cummins12V98]

I would not think so but it was a hot item at one time. Do you have the stock module in the tank ?

no idea.

Well a replacement VP-44 is only a little over 1K, so no big deal to spend 150 bucks for a fuel gauge!

so I already have a replacement fuel pump and filter system. What will a pressure gauge do for me other than clutter up my dash or pillar?

 

[Cummins12V98]

Yup, mine was 14 years old before I added a pressure gauge, still on oem ve pump.

The guy I bought my 98 12V from bought a 01 and he kept laughing at me when I told him to replace his lift pump. His VP made it to nearly 400k.

It will tell you if you loose fuel pressure to the VP-44. Lost of fuel pressure to the VP-44 is one of the major causes for failures, as fuel lubes and cools the pump. Others are heat(kills the electronics in the pump) and those that came with a brass bore(like my 2001.5).

Yeah for him. Mine made it to 52K.

What SnoKing said = "No 24V should be driven around the block without one."
LMAOROF. But, IMHO I'd have to agree. One the first things I did (bought 5/01) was install gauges; fuel psi, trans temp, egt/boost combo in tri-a-pillar mount (probably 7/01). Cheap insurance...
Anyhow, and on topic, check everything possible and potentially related "it-is CHEAP", much more so than "throwing new parts" to see what fixes it... just saying

This is why a pressure gauge should be the #1 gauge. I would have burnt up my pump without one. It has been preached on the TDR for a very long time.

Only upgrade I have done is new Bosch 275’s.

What are those going for nowadays? I ran a set of those in my 2000 RAM 2500 Quad Cab Sport....

EGT, boost, transmission out line, and fuel pressure.

I have a set on order from DAP for $379, and $149 for the tubes.

BTW, I had two transmission sensors with a switch at the meter. I sensor in the pan was worthless, as it would have notified one that they had just destroyed their transmission after the fact.

 

[Cummins12V98]

Yeah for him. Mine made it to 52K.

He used AMZ/OIL fuel conditioner!

Seems like I paid around $375 for the set.

Nice truck!

Sounds around what I paid. My son did the swap and he said all I needed were the injectors. Maybe washers? Don't remember. He has done injector swap many times on 24 V's.

Injectors were swapped over a year ago.

I am not arguing the reasoning for the FP Gauge, simply will deal with it if I ever need to.

Genuine New Bosch 275 RV injectors are nearly impossible to find lately. At least they were when I purchased a set back in July. A set of 6 cost me $510 with no core charge. A new set of 6 crossover tubes cost $251.70. At the time, Geno's Garage was the only place I could find who had them in stock and they only had 7 of each. The current cost of these injectors has risen to $588 but the crossover tube's price remains the same.

Fuel pressure gauge is a preventive thing.

Fuel pressure gauge is a preventive thing.

I understand, but what happens when an AirDog dies? Does it slowly deliver less pressure or???

 

[Cummins12V98]

DK Diesel is where I bought mine for $375 I believe. They show out of stock now at $395

I did the flip on and off the ignition thingy. I am guessing this means all is well???

Isn't the AD the one with the bypass check ball near the pump. If so it at least use to have a plastic ball with a spring and has been known to wear causing the fuel to siphon back from the engine to the tank causing hard starts. Or am I all wet and thinking of a different system.
