We have this New 600 in our shop and I hooked up all the gauges. (Auto Meter Cobalts) I road tested the truck down the road and back. (MAN DOES IT GET HOT QUICK! LIKE 1400! HAD TO BACK OUT OF IT! WHATS THE DEAL WITH THAT???!!! The old Rams were not like that!) Pyrometer and Boost work great....from what i saw of the boost...maxed the gauge out. Fuel pressure didn’t move much. Maybe saw 2-3 psi. I have it tapped into the banjo bolt that would be in about the same spot as the VP44 unit. Is this a return and why I am not seeing pressure? It is the line coming from the filter housing...and another line going to the rail. I assume that the pressure is not that high due to the rubber hose and pinch clamps. Any suggestions would be helpful. Thank God its a banjo bolt...I can swap it to almost anywhere.

The truck has injectors, TS 600 Ramifier, intake, and custom dual 3" exhaust.

Thanks!

The bottom of the filter housing is the place to tap, these trucks only have about 8 psi at idle with those mods I am supprised you did not see 0 psi pressure as an EZ will draw down to 1 psi on its own on my truck. You will need to look at upgradeing your low pressure pump soon.

You can also follow the line from the bottom of the filter over to the cp3 and use that location. Its easier to get to there and I got the same reading as the bottom of the filter.

Crabman does this give you post filter pressure readings? I had my 99 setup for post pressure readings and it was nice to know that it was the filter getting dirty or the lift pump was taking a dump.

If I got low pressure readings I would change the filter and then I would know if it was the lift pump or just the filter.

I'm not one to run a fuel filter more than 10k miles, but it still is subject to dirty fuel. It only takes one tank of the nasty stuff to plug a filter.

I went with the line from the bottom of the filter to the pump (Tapped the Banjo at the pump). I am getting about 7-9 PSI now. Seems a little low but the truck has 1200mi on it! What is the stock on these trucks suppost to be? Thanks!

It is nice to get the post filter reading so you can keep tabs on your filter condition. In this cas they are both post filter. The line referred to is the fuel line from the filter to the cp3. The cp3 end is a little easier to get to and work on as far as the installation goes. I am not aware of an advantage outside of this insofar as choosing the filter or cp3 location.

It all depends on wether or not you are using an isolator or a braided stainless line. If you are using the stainless line you get less incab noise using the filter housing versus the pump fitting. I talked to Rod at Wildcat about this and I used their stainless line and attached it to the pump first, it did not take me long to move the location to the filter housing. I am glad I moved the location.

Would the top of the filter, using Geno's tapped cap, be post filter?

I think I am just going to tap the top of my filter housing versus spending the money on Genos cover. It looks nice but its a bit pricey. I need to look at a fuel flow schematic to be sure if the gauge would be pre or post filter then.

Diesel-Dan

We installed the FASS and it made a world of differance in fuel pressure. I got 17 PSI of pressure at idle and could not get the needle to move past 15-16 WOT....but the EGT's are still 1700 degrees if you stay in it! Will the ATS manifold help with this prob? Or is there any turbo housing that we can look into? The one on the truck seems a bit small.

I believe that the top of the filter is prefilter pressure. I would just use a tapped banjo bolt an go from the bottom of the housing, as the only thing you need is the banjo and a gauge setup.

I used Geno's fuel pressure line which screws on to the shrader valves. Its located so I can move it from the shrader valve right after the lift pump to the shrader valve near the injector pump, that way I can tell if I have a dirty filter in less than a minute. I normaly leave it on th shrader valve near the injector pump. Works good. 13psi at idle 10psi @ wot.

Bringing this to the top again for confirmation. From the comments here and from talking with Rod, do I understand correctly that in order to connect to the clean side of the fuel filter, the following is true?

1. A single Banjo on the under side of the fuel filter cannister is replaced.

2. the Banjo's that geno's sells for the 2nd gen 24V engines will work. Only one tapped banjo (with 3935171 gaskets) is required.

2. The Genos fuel filter cap is actually the dirty side of the filter

thanks guys. oh, and this is for the 3rd gens.

BADBOWTIE

The info you have listed is correct. I hope that the people using the lid that Genos sells understand that they are seeing prefilter pressures.
