My fuel pressure has dropped from 7-8 pounds to 4-5 pounds. I believe my lift pump is going. I've already purchased a holley pump and parts to install it before my fuel pressure dropped. I'm unable to install due to surgery on my shoulder. I have the engine mounted pump. Should I try to get dodge to replace it with the intank pump and then when my shoulder is better put the holley pump on? Should I wait till it fails completely and hope I can install the holley pump when it dies completely? Any advice would be appreciated.

P.S I just replaced fuel filter to make it wasn't causing the problem.

Thanks

I would let the dealer install it if its under warranty, and then have the option to upgrade with the holley pump and a big line kit! Then you can still have the OE pump in the tank as a back up! I've seen that somewhere on here.

 

Id return the blue pump and get a walbro pump

 

I wouldn't waste my time with the in-tank pump. Because when (not if) it dies and you go aftermarket anyway you'll then have to drop the tank again to install an aftermarket fuel pickup because you can't pull through a dead pump. Atleast now (without the in-tank pump) you can use the factory pickup with most aftermarket pumps.

 

Dealer probbly won't touch the pump till it dies and yes they will put the in-tank kit in. The holley blue pump is not ment for diesel fuel and some people have had problems with them. I would just go with the Glacier system and you will never have to worry about it again. Don't even have to drop the tank and only a 3-4 hr install.

 

2.5 hours with the walbro kit its great and very easy it install

 

What do you mean "don't even have to drop the tank"?

 

On trucks with the engine mounted lift pump there is no need to drop the tank. The factory pickup is used.

 

The reason I didn't go with Walbro is the cost of 400-450 for everything plus the install. I know...install it and never look back. The other main reason I'm looking at the replacement in-tank pump is because I really really can't install my own until maybe late August due to my shoulder injury. I also can't afford to have the current one fail while I'm on the road. I spoke the dealer today and told him that I wanted the old pickup that they would take out of the tank so I could have it for later when I might upgrade. He didn't think that would be a problem. He told me that I needed to tell them that it stumbled under hard accelleration and they probably wouldn't give me a hard time about replacing it. I just wish Dodge installed a reliable pump to start with.

 

HI Todd

Does your pump have 7 or 8 at idle and then drop to 4 or 5 while driving or does your pump now have 4 or 5 at idle? Mine usually has 7 or 8 while driving but will drop while excellerating.

 

It used to have about 7-8 at idle. This morning is was between 3-4 at idle. I know I could pull it to zero just with hard excelleration. By the time I got to work it was between 4-5 at idle. It was ok at 7-8, because with the 60hp setting on box I would only pull it down to about 4-5 when I really opened the throttle or when towing and got above 2100 rpms.

 

Don't forget to take the box out before you go to the dealer for any diagnostics or work!

My friend, that is an awesome write up - - thanks.

I have not messed with the fuel system except for adding a guage. So, please answer some really dumb questions if you would. Oh, I do not run any boxes - - pure stock.
1) where is the stock pump?
2) what is the problem with the stock setup?

Guess I have not been following any threads on fuel pumps close enough. I am still running at about 8 to 9 at idle and 6 or 7 with the fiver on with the pedal buried on a long hill. Sounds like I am still in good shape, but I guess I better be thinking about it and find out what is important. Thanks.

2003 through 2004.5 have the lift pump on the filter housing, which is on the engine. There have been enough cases of failures to prompt Chrysler to discontinue direct replacements and install an in-fuel tank pump instead when the originals fail. 2005 and newer already have the in-tank pump, so only those would require the fuel tank to be droppped, like the write-up for the home-brewed Walbro set-up outlines. toddbweaver wouldn't have to drop his tank for a Walbro conversion because he has the earlier version.

Punch in "lift pump" in the search box and you will find all the discussions on the filter housing/engine mounted lift pumps.
