Hey everybody, I hope you can give me some honest input here.

I want to install some type of an aftermarket fuel system on my 2006 Dodge CTD CR but I DON'T want to drop the tank and install a different pickup etc.
I have that on my 1996 Dodge CTD 12 valve and experience "cavitation problems" if I let the tank get much below 1/4 tank.

I am aware of the Jeep Liberty in-tank "fuel canister" option, but my question is; "Are any of you running any type of an aftermarket fuel system WITHOUT having dropped your tank and with the stock "in-tank" fuel pump still there?"

If so, have you had any problems with that set-up?

What type of fuel and rail pressures do you see with it?

Thanks alot.

I'm running a early Air Dog FP80 and using the stock pick up. I just unplugged the old stock line and connected the fitting that came with the Air Dog. I'm also running a inline bypass regulator set at 25psi and it doesn't move much.

 

his 06 has the pump in the tank I think he will have lots of problems trying to suck fuel through the factory pump. John if you dont want to drop tank pull the bed off. loosen the bed mounts on the passenger side and remove on drivers side and the slowly jack the bed up far enough to get to the puckup assembly.

 

Over looked that. The tank will have to be dropped or the bed lifted. If you drop the tank be sure to support it in the same places it's strapped to the frame while fitting the tube. If the tank is sitting flat on the ground you'll most likely cut the pick up tube too short. The tank sags a bit where the pick up tube is when in the frame.

 

I run a holley blue between tank and cp3 and left the stock lp in the tank with no problems. I can hold 14psi at the cp3 on wot runs using the tnt/r and it holds 21psi at idle.

 

I appreciate all your replies! I apologize that I forgot to tell you guys I do have a 2006 with the "stock in-tank pump." Thanks Robert!

TORQUE BEAST:

Thanks for your input Sir. You are one of two guys so far that have told me this could be done. Thank you for that. Can I ask you how long have you been running your current set-up? The reason I ask is because the consensus by almost everyone I talked to is that I could not put a pump "in between" the tank and CP-3 with an 06' that has the stock "in-tank" pump for the reasons cited by Robert.

But if you have that type set-up in your 05' and it is working, I think I may give it a try. What type of fuel pressure did you see with your truck with the stock set-up? I see about 10lbs at idle and the F.P. rarely gets below 8lbs under normal driving. Sorry for all the questions, but thanks alot in advance for any input or advice you have. Currently I have a Walboro 392 which was almost given to me by a good friend who had to go to a much bigger system on his 06' due to performance upgrades. I was thinking of just using that pump like you have with your Holley.

I have had it on there for around 10k and it is working great. I had 9lbs at idle with just the stock intank setup but with I could drop it down to 2 lbs on wot throttle runs with the 4.2 beta. All I did was install the holley inline and tied into the power source for the intank pump and used a relay so the holley turns on at the same time the stock pump turns on. I now have 20-21psi at idle and with the tnt/r on #9 wot I can drop it to 14psi. Putting the pump inline helps take stress off the stock pump so it should run for a long time and I was told that if the stock pump failed you can still draw fuel through it with the inline pump. There are a few people on here that have done the same thing. When I researched it I talked to a few that have been running this same setup for over 2 years with no issues. The only thing you may have to do with your walbro is add a regulator to control pressure. Just keep the piece of tubing you cut out just in case your walbro dies you can put it back in so you can get home.

Thanks alot for all your information! I appreciate it very much. Heck, I ran a Holley Red on my 2002 Dodge CTD and may just go with a Blue like you did.
I had real good luck with that Holley Red as it was almost three years old when I sold the truck.

John, I dont have a 06 but I will try to run the line from the stock output to the input of my walbro. I have been wanting to try it to have a more useful fuel capacity. I also hate watching my FP gauge drop out during heavy braking and launches. I really believe that using the stocker as a pusher to feed the walbro would provide enough fuel for a decent level of performance.

Thanks for your input. Yes, I agree with you and I plan on doing something similar to what you and TORQUE BEAST have recommended here. Right now I am not planning on going real drastic with the power level on my 06' as I have my 96' Dodge CTD 12 valve for that. So, IMO, I think a set-up as you guys have described will work alright for my needs. Like you guys said, I just want to get that F.P. up some more from where it is now.

Thanks alot.

If you decide to go with the holley blue you won't need the regulator and the nice thing about the holley it only takes $15 to rebuilt if needed. Also if you use the holley blue make sure you take the bottom off and remove the screen inside. It will make the pump last alot longer.

 

I have a Holley Blue knock-off in my garage waiting to be installed inline with the factory in-tank pump. Plan on doing the relay triggered by the stock pump. There are several people doing it like this, and I think someone has a Raptor setup like this.

Thanks for all your input!

Yes, I had done everything you posted above with my Holley red when it was on my old (now sold) 2002 Dodge CTD. I know there are Members that don't care for the Holley's, but honestly, I have had excellent luck with them on my trucks.

Hows it going John, i also run a Holley Blue in line with my factory in tank pump and it works well. Been like that for over a year and 10k+ pressures went from about 7-8 to around 21psi or so, i did 501.xx at denton with this set up also with my reg. ol PPE. Good Luck, i dont blame you on not wanting to drop the tank! Ryan

Ryan:

Hey buddy, thanks alot for your input too! I appreciate it very much.

Yeah, I am almost positive now after your post that I am going to go the route both you and TORQUE BEAST have with the Holley Blue. I can get them at a good price through my Manager friend (Greg) at our local "Advanced Auto Parts" here. He gives all our diesel guys a one-year warranty on them and has stood fully behind anyone that has had problems.

BTW,....CONGRATULATIONS on your new dyno numbers Ryan!
