Lift pump replacement
 

Well... I got to replace my lift pump, and hopefully my VP isn't hosed. Any helpful hints? Maybe what not to do's? I've never did one, do I get it from top side, or underneath? Looks kind of like a bare, maybe not, we'll see...:w2: and I'm going with a factory replacement, how about the quick disconnects on the fuel lines, how they come off???

You can get at it from the top pretty easy. Thats how I got mine out when I put in the FASS 150. There shouldn't be any quick disconnects around the lift pump, just banjo bolts.

So the banjo bolts just screw in to both sides of the lift pump? :humm:

on my 00 i could get at it from the top or also from the bottom by pulling the starter.

Also there are some new lift pumps that have quick disconnects it just depends it this one has been replaced before.

Billy D i would recomend to go ahead and pay the money for something along the lines of a fass or airdog. Espically with the comp. Ive put two pumps on in 62k and this last one was replaced in april is going out now.
for what i spent on these two i could have almost bought a airdogII:argh:

Yep, on both sides. I just went and looked at the one i took off mine.

:humm: first what not to do is going with the factory replacement :scare2:
I would go with an air dog but others prefer fass
they are easy enough to install that I did the air dog 150 on mine in the front yard
do you have a fuel pressure gauge if not perfect time to install one since you are working on the fuel system :tttt::pca1:
lots of write ups on here on air dog installs

And Edge Comp and oem lift pump is NOT a good idea.

Yeah the Edge can do some damage. I babe my truck, I run it on level two:w2: Do ya think it had something to do with eatn my LP? I want a AD150, but my funds are super limited. I might need a VP:dang: I want an AD150:argh: My LP seems to look like it has some kind of quick diconnects

if the lift pump looks like the pic added yes you do have quick disconnects

if it mounts as a vertical unit then you have all banjo fitings

Also I told myself i didn't have the money but now i wish i had put the ADs on in the first place. two lift pumps @ $150 min that comes to $300 and ive seen ADs going for $500 And with the edge trust me you will go through stock lift pumps fast

raptor 150 $399 place an add in git a price quote. I know money is tight but vp's are high. I know you said you were going with factory so sorry for pushing info but i think eveyone agrees

raptor 150 cant go wrong if you are on a budget :tu:

Well Said

I have had 2 CTD's now..the 1st a 99 and I went with a GDP walbro w/big line kit...loved it 17psi constant...problem is you can buy the big line kit but you cant get the walbro with it anymore...big line kit I think is around 150 and you can get a walbro pump on ebay for 100...make sure you get a pressure regulator to restrict the pressure on these walbros....search Glacier Diesel and I am sure he can help you out on piecing it together.

my new truck (to me, see sig) I went with a raptor 100...supports about 500 hp'ish and I love it...install was simple took me about 3 hrs...but I double and tripple check everything...price was 389 plus a friends discount out the door for 355....comes with everything you need....big lines, bango replacement, and adjustable pressure ability...LOVE IT.

What's your Raptor getting for pressure compared to the Walbro?

I would replace all you banjo's if you don't do anything else. A few years ago before I even knew about these diesel forums I replaced my stocker with another stocker and left it the engine bay. Right after I found these forums and immediately ran larger fuel line, moved the stocker back toward the gas tank and added a cheap Pro Comp behind it to do most of the pulling. I put an inline filter in before these 2 pumps also. This was a budget build that cost me about 200 bucks for everything. I also put in a pressure gauge which is worth it's wait in gold. I was getting 28psi at idle and 18 at WOT and 2 years later I could tell one of the pumps were getting tired because I was running 22 at idle and 15 at WOT and just 2 days ago one of the Pro Comp died when I was 2 hours from home. Good thing for the pressure gauge and the second pump. I just went to a parts store and bought a Holley Blue because they do not carry the Blacks, swapped pumps in about 20-30 minutes and I was on my way. This setup lasted 2 years without a problem and the crappy stock Carter is still going.

Raptor 150 and Vulcan Filter to Injection Pump kit and you will be set. :tu:

28 psi at idle for my money is WAY to high...some people run them that high but from my research and reading, it can do more damage to the injection pump then good for it. the plunger doesnt need that much FP and most people say it actually will hurt it...

20psi is PLENTY, dodge/cummins say the threshold is 5psi (below that "could" cause damage)

just my 2 cents.

I'm looking at replacing mine, I'm curious why you cant just loose the stock lift pump and install a carter thats putting out 100gph and 18psi right off the gas tank for $150 ??

:humm:

if your going to spend $399 on a raptor fuel pump, you should probably just get the airdog 150 for $499. Its not much more and you get a whole new fuel system up the the vp. I installed mine in my driveway. And i put an ad in here and bought it from a sponsor :tu:

whats the point in wasting the extra money...these are 2nd gen trucks...they dont need the "EXTRA" ohhh and aweeee filtration of the Airdog or Fass....they are not a common rail that needs that 2 micron filtration and are not as harmed by bad filtered fuel...the stock filter will provide all the filtration you could need...extra cant hurt but to me it's like taking a leak in the wind......

My lift pump is now working most of the time but noticed it didn't kick on correctly.I have been keeping a eye on it since I bought truck in Dec. because of this site! The one on it now is a Air-Tex and the previous owner said he put it on a little over a year ago(It was bought at Advanced Auto with lifetime warranty&now they are refusing to replace it because it has went out twice before)and I am on a very limited budget(because of paying cash for truck)It will start(does not have fuel gauge yet!)now but I'm not driving it because I can not afford new injection pump.Im hoping I caught it in time.Does any1 have a good used 1 for sale or what would be my best bet for now(need something I can afford that will last&work good for 3 months so I can save)that's under $300?Pump is on engine block&How hard is install? Thanks for any helpful replies

I feel that all the advice on the pumps is a bit misleading.
I use Carter pumps (like the OEM, but improved).
One on the frame, pulling thru a 30-micron filter, and
feeding a 10-micron, and the one on the block as backup
feeding the stock filter, with a 2-micron after that.
>20 PSI at idle, 18 PSI at max pedal.
The key is low restriction - replacing the banjos helps marginal
installations and modded (high HP) systems. Same for bigger lines.
BUT, for a stock system, the OEM pump is fine, as long as it is good.
You can take them apart and burnish the gears for some improvement
if they are scored.
Here is a source for the Carters:

They also have the FASS DDRP's for folks who don't believe the above. :)

I replaced the carter yesterday it was a tight spot but not hard to do.They gave me a new air-tech to make up for the carter that was the old style pump.It picked up prime first bump of starter and is running great.Now got to get a fuel pressure gauge and cross my fingers it didn't get my injection pump!:scare2:

I got my lift pump on Advance made it up(thank God because money is tight right now)and gave me the latest Air-Tech available(goes in sideways)and it started first turn.My friend owns the local NAPA store and said that all Air-Tech lift pumps are junk? I will put a FASS or Airdog on when spring comes(And my work situation/$ is better)and farming picks up.Now I'm still getting a slight hesitation at idle.My truck runs fine other than the idle miss at low RPM's any suggestions?
