Engine/Transmission (1998.5 - 2002) "New style" Quad fuel pressure sender

[Spunkys Ram]

Well, I got my 'new' FP sender for my Adrenaline and couldn't wait to install it... so I did. Guess what?



The Pulse reads 18psi WITH THE ENGINE NOT RUNNING. #@$%! I switched the wires around on the sender (ground-signal/vice-versa) and no change. It reads 30 psi with the engine running. I know I have more then 12 psi. I am starting to get a little frustruated with the Adrenaline/Pulse. I know it's new, but... ... :{



SOMEONE PLEASE HELP!!!!

 

[Wyomingcowboy]

good luck... . quad has jerked a bunch of folks around with their FP senders/units.

Sorry I am no help... . but I feel your pain!

 

[Spunkys Ram]

I know Quad will get a right. I'm pretty confident I did everything right. I'm just looking for some help.

You have adjustments on the Pulse for fuel psi, adjust it down to 0.

 

[Spunkys Ram]

Tried that, only went down to 12 psi. Any other ideas?

 

[Cummins724]

I have a 0-100psi sensor that I hooked up in my brothers 98. 5 & it does the same thing. No matter how far you adjust it, it shows 12psi with the key off although it is fairly accurate when running. I bet you got the wrong sensor.

 

[Spunkys Ram]

I got my sensor straight from Quad, so I hope it's not wrong.

 

[DirtyDodge]

Mine will be here tomorrow, I'll post the results after it is installed.

I have the sensor that came with my beta box & it reads very accurate, but jumps around alot at wot. It reads 6psi when the truck is shut off. I still have my mechanical gauge to keep a extra eye on it. I never trust digital gauges.

I'll be waiting...

I need a recommendation on how to install this. I have the FASS hard plummed to my VP44 through a "T" aN fitting to run a mechanical fuel pressure gauge. Will I have to splice into the line with another fitting? Is there another spot on the FASS where I can pickup the fuel pressure? Don't mean to hijack this thread, just want to install it so I can post my results.



Thanks,

Derek

I just got one of these & installed my mechanical gauge inline. Fuel Pressure Tee 1/2 Pushlock

There are problems with some of the sending units, they read all over the place. Mine goes from 0-18 and back. With my Fass I clamped a pipe clamp around sending unit with a wire that runs to ground. make sure its tight. Jeremy told me they are testing a new version right now.

I got the following from Quad and I am sure they will get it figured out.

I most certainly under your frustration. Its frustrating on my end as
well, believe me I would love to be Able to sell to all you guys that so
desperately want the sending unit, if only I had them. The units on our
website we a limited supply and ran out quick, I do apologize. I am
told more are/have been on order but the eta is disclosed for some
reason. I would be most happy to provide you with the specification on
the unit, and if you need to purchase the banjo fitting and Genuine
Cummins washers for the fitting I would be happy to sell them to you,
cost is 10. 00 + ship. The sending unit we utilize is a 0-40psi
resistive type fuel pressure sender, oil sender will work but longevity
may be a concern. Ohm range is 240-33ohms. Keep in mind that the
closer to a 0-40psi unit that you can find the more accurate it will be,
if you use a 80psi for example it will most likely read slightly too
high. Stewart Warner or ISSPRO are viable options, worth looking into.
Please understand we will try to do anything we can, we just don't want
to sell you guys junk sending units, and why this has been drug out so
long. Please contact us anytime with your feedback or questions.

With all due respect to Quad, and their excellent products, I find it difficult to comprehend that with so MANY commonly available fuel pressure senders, they would choose one so unique or oddball, that a quick and easy substitute is so hard to locate and provide...

I 2nd that Gary. For a company that relies on repeat and customer recommended business they appear to be in no hurry to right their wrong.

For the moment am going with the glass half full at this point. I had asked in another thread if anyone had sourced one using there spec's. Since nobody came through maybe not as easy as it seems. I have all the faith in the world people here would have found a source if there was one I have not tried yet though.

"Their spec" is exactly the issue, as I understand it!



Supposedly, they designed the Adrenaline/Pulse AROUND the resistance spec of an unusual and uncommon fuel sender - and when THAT source evaporated, there are no readily available senders that provide the proper resistance range to properly function with the original design circuitry of their control head. SO, they either have to FIND a suitable alternative sender that matches the original one they designed around - or else redesign their control unit to accommodate whatever substitute sender they might settle on.



To me, until this SNAFU is corrected, the glass is definitely half EMPTY!

I can't argue your point Gary because I agree. Having said that though the resistance type sensor you would think is an easy, inexpensive and you would normally think reliable. It is not unusual for design and real life not to line up as we would like. I kinda adhere to the KISS principle and the resistive sensor would match that philosophy. As a retired Engineer I have been there done that and it is frustrating. It seems to me they did an excellent job with everything but the sensor in the design and only time will tell for sure. I have a feeling a lot more design effort went into the Aderenaline/pulse than "the simple FP sensor" and was surprised when it did not work as designed!!! For now will still keep the glass half full and see if they recover from this little glitch as I fully expect them to and watch my existing FP gauge.
