ladies and germs, i will be doing my install tomorrow as its cold and snowy out but i have everything prepped ready to bolt up and run.edited as i found all my old hardware and a new oem lift pump. so i installed per instructions from GDP.

I have no idea... but COOL!

Just one filter?I would put a f/w sep before the fuel boss, like a Balfwin BF1212 or Fleetguard FS1000.

after house sells ill be doing something like this and adding secondary lift pump. i just dont have funds right now

- - - Updated - - -

so i ran into teathing problems, the install was tedious but straight forward. However ive run into a snag and am currently working with rich to solve the no prime/no pressure issue.

I will say that he has been a very standup guy to work with and he has made a life customer out of me! i give him 10 thumbs up!

i will update when truck is running.

Can you just pull the fuel from the stock canister? That way you have a filter before the pump. Just a thought.

I wouldn't, that's a pressure designed filter. Filter bases and fittings are cheap.

I notice some people when they install after market fuel pumps they install a fuel sump I know there are pros/cons to everything. But would that be a good idea to install a fuel sump or to plumb it the way the company suggests to? Hope what I am asking makes sense. Ok one more question if you had the funds would just buy one to upgrade or would you wait until the stock pump went out?

Upgrade ASAP. If you wait till your stock one goes out, you have already damaged the VP4, maybe not detrimentally, but not worth a $10000 dollar chance.

But what if you do not have a VP44 my truck is an 05?

Sorry, I can't see sigs on my phone. If you have a newer common rail your in pretty good shape, the cp3 won't burn up quite like the VP will, however I would still recommend an upgrade asap and maybe a cp3 from a dirtymax or a bag o parts. (Cp3 upgrade not lift pump.) The common rails have a huge upgrade variable based on what you intend to do with the truck as an end result.

Unless your at least 800hp a sump is not needed, even then I am not sure it's 100% necessary. I will probably do something around the 100K mile mark, that will be over 3000 hours on the OEM pump.

Hey Thanks for the advice. So instead of a lift pump like a fuel boss just upgrade the CP3 that's what you are saying right? My end result with my truck is to use it to haul and a daily driver I am not going to be racing or sled pulling. I cannot afford to pay and play

Don't worry about a modified CP3.

So would you just go with a fuel boss or DTT fuel pump then or wait until its about to crap out? The only reason I am asking these questions is I want to stay ahead of the curve I have 95,000 miles on my ride and I do not want any big expensive problems down the road. allot of good comments or responses

I haven't decided if I am going to go mechanical or electrical yet. Lots of people get 150K or more out of their OEM lift pump, but I am more in the preventative mind.

Yeah, I was not saying to replace the cp3 unless you plan to upgrade power quite a bit. In cant hurt to replace the lift pump regardless.

I'm at 220K and pretty sure it's the third lift pump on my truck, but still feel like I'm driving around on a time bomb with it, hence my preventative measure with my fuel boss. Richard did mention that one of the causes for pump failure is fuel starvation and he mentioned that a restriction before the pump such as an aftermarket filter system could cause premature pump failure. That might turn some of you off from the fuel boss. I'm not sure how much strain a f/w and separate filter might put on the fuel boss. If anyone has done this, I'd like to know.

The 2nd gen fuel pump is a much more prone to failure unit than the 3rd gen in-tank setup, but they still don't last forever. If I couldn't put a filter before the fuel boss I wouldn't get it. Personally one of the big reasons I want to change lift pumps is to get a pre-pump f/w sep installed.

My buddy got a smoking deal on an early 04 from a co-worker because it has a dead lift pump. 1st one lasted 195k on the block and he went to oreilly and picked up another carter. I would put a fuel pressure gauge on it and not mess with it until it goes out.

That had been my train of thought - if it ain't broke..., but went ahead anyway.

So after 2 days of working on the truck due to a possible pump and crud in a check valve, i am now running only on the fuel boss for testing and purging. Long story short, i had to run a completely new supply line from the tank as i was not getting pressure. the first new pump seemed to be out of spec and wouldnt prime/pressurize. So after taking half the plumbing apart and inspecting the check valve i found a chunk of crud keeping it open and the fuel boss was hydraulically opening it up further creating a loop to where it wouldnt pressurize. So after cleaning it the system works as advertised! At idle i run ~15psi anything above 1800rpm im @ ~18psi.i tried to bring it down on setting 5 and it wouldnt go past 14psi.I was able to find all the original hardware plus the brand new OEM style lift pump i got back in the day when i replaced the vp but went with the raptor that eventually died. I currently have my system plumbed the way GDP has it in the instructions with the OEM lift pump inline after the check valve to preprime the system and hold as a temp backup in case a belt breaks of catastrophic pump failure.Things i learned from this instal.take your time, and when running the hoses, do one line at a time in sections and "piece" it together. you only have one shot to get lengths right and i had 5' left over (if you plumb to oem steel line from tank).be smart about line placement in engine. i zip tied mine up and out of the way to avoid pitman arm and steering shaft rub.heat the ends of the hoses with a blow dryer, they will push onto the pushlock brass fittings easier. (i put hose clamps on all mine anyways).ensure no lines are kinked, restricting flow.ensure bypass valve is oriented to flow toward the tank on the pressure line from fuel boss (you will destroy your filter lid) <-- this didnt happen to me.ensure check valve is oriented toward inlet of oem lift pump and that it functions properly before install.if for any reason the fuel boss doesnt prime and create pressure within a minute or less you may have crud in the check valve keeping it open making a low pressure loop feeding itself and you wont get the good pressure.belt slack basically i have mine to where you pull the belt to itself gently and it is as wide of a space as the small pulley. looser is better!and most of all,Working with rich at glacier diesel has been for lack of better words, excellent! He next day aired a new pump to me to eliminate the original pump if it has issues and he was very happy to work with me to get this right. He has made a life customer out of me. I have never had such great experience with a business much less the owner as i have working with Rich.I give Rich and his business 5 stars!
