fuel pressure.

[Kurt Henzler]

if you have 305/555 motor and want to monitor the lift pump and its pressure, what are my options. is there only one kind of set and connection or are there different ways to hook it up. i would like to do this , but do not know what to buy.

thanks for the help

Geno's sells a Billet Fuel Filter Cap to replace the stock plastic one.

It has a 1/8" tapped hole for a fuel pressure sending unit.

I haven't ordered it yet, but plan to.

DiPricol Fuel Pressure Gauge Pics.

Kurt...

I have my DiPricol fuel pressure gauge set up post filter off the CP3 pump with an isolator. All you'll need is the fuel pressure gauge kit (gauge and install kit combined) and your choice of mount... . I have the SRT/10 A-Pillar mount. Here's a link to some pics if you want to check them out. You may also want to use the search feature and read past posts concerning this topic.

Mine is set up post filter right at the line going into the CP3 pump, using a banjo bolt. Been working fine that way for over 35k miles, no leaks no problems. No hassle with having to disconnect it, like you would have with the fuel filter cap. Pics in my readers rigs. Oh, also have it going through the isolator mounted on the firewall lip.



Gauge is in a-pillar.

i have the billet filter cap. i am not too worried about filter changes. it only takes 5 seconds to disconnect the line from the top of the cap.



pressure runs between 5 to 8 psi . seems to be temperature related. lower when cold.



pressure reading might be different from the banjo bolt at the pump. has anybody checked this out?

Nope, LRC, you get the same readings I am getting. Always has been that way since installed. And you're right, it is temp related.

does eveybody agree that a isolator is used. do our lift pumps show weak pressure before they fail? or do they just quit

I want to use an electric sender and thought I would tap in a the CP3 with a bango bolt but am not sure if I should put the sender right in the banjo or use one of these



On that page it doesn't make sense to me to use the hose then they say you need the sender and engine to vibrate together??

I am confused.

In the Geno's catalog, it says the banjo bolt fits the 98. 5 through 02.

Mine is an 04. That's why I thought I would need the tapped fuel filter cap.

I would prefer to use the banjo bolt if it will work on my engine.

I have not called in my order yet, so could you clear this up for me.

 

[lil red cummins]

there is a banjo bolt for the 04's. lightmanE300 just installed one on his.



i did not go with the isolator, however i do have a needle valve shutoff right on the filter cover. it is opened just enough to allow the gauge to read pressure. if anything should go wrong, i can quickly close the valve.



haven't used an isolator in 35 years. never had any problem yet.

Hey Greg, where did you get your banjo bolt from?

Matt... .

The banjo bolt came with the DiPricol fuel pressure gauge install kit that was purchased along with the gauge. The guy that performed my install also said the banjo bolts were also individually ($3 or $4 each maybe) available from Geno's Garage. To my knowledge, there's no difference in the banjo bolts used on a 2nd GEN 24V and the 3rd GEN HPCR engine..... maybe a previous owner of a 2nd GEN 24V that had a fuel pressure gauge can chime in and let us know for sure.

Thanks Greg.

 

[Jengle]

Same here. My banjo bolt came as part of the gauge installation package.

 

[GRudy]

Is this right? Only 5 - 8 psi? Sounds awful low. My 2nd gen with the new lift pump is putting out 14 psi. before the filter.

 

[lil red cummins]

thats all i see. truck runs fine. haven't had the box over 6,6 since new turbo install. no problems with running out of fuel. as much smoke as you want!

Well, the 5-8 that we are seeing is post filter. According to an article by J. Donnelly in one of the previous TDR magazines, we have a different pump than the older gens, and this one is only rated at 10psi max with no load. So, 5-8 is about right for a post filter reading. Apparently this is enough, since it is what a stock truck is supplied with.
