injectors
what size injectors will the stock lift pump on my 99 Dodge Cummins support? It only has 107,500 miles on it, so the pump should have a lot of life left in it.
|
What kinda of fuel pressure is your lift pump making?
Luke |
Yes i agree with luke makes sure your making good fuel pressure at your pump before you do anything powerwise
|
Reason for this is the stock lift pumps generally only flow enough for stock power levels, at the best. 10PSI at WOT is minimum to ensure VP44 longevity.
|
stock lift pump = stock injectors. put a fass on it and be happy and able to run anything you want.
|
I agree, get rid of that pos stock lift pump before you have to replace your pos stock vp44. then start thinking injectors.
|
get a raptor 100 or 150?
|
I haven't checked the actual pressure from the pump, I would think it still has all it's pressure it's supposed to be pumpin, I don't know what that is though.
By the way guys I REALLY appreciate the help, but watch your abreviations. I'm just a farmer thats decided to juice up his ride so I don't know what WOT and FASS mean !! Bear with me, ok? I'll get there I promise. And to be totally honest I got a bit jealous after my son and I worked on his 93 Dodge 12v then I drove it one day he wasn't here and it runs like a raped ape !!!! I got the bug from my earlier days. |
Wot means wide open throttle and fass is a company that makes an aftermarket lift pump.
|
:rocking:when you get the fuel pump (i got the raptor 150 happy happy with it) get an quadzilla adrinaline box or a edge comp box & rv275 injectors all the venders can hook you up on all those, it will come alive, o ya almost forgot, helps to have better flowing exaust , (just my 2 cents):tu::tu:

What tools are needed to R&R fuel injectors in my 98' 24v
|
Pretty much basic hand tools, metric of course. 10mm, 13mm, wrenches or sockets and ratchet. 7/8" line wrench for the lines, I believe it is 7/8". A medium length pry bar to pop the injectors up. There is a special too to put the fuel tubes out, but I found a good small screwdriver did the trick as well.
This thread has a lot of information in it: https://www.dieselbombers.com/5-9l-2...tallation.html |
good luck, its not that bad at all:tu:
|
Just be patient with it and do it right... Keep EVERYTHING clean it should take about 1-2 hours for the first timer.

Its a 19mm but 7/8'' should work fine :tu: |
Ive used a 7/8'' to get a line off before...
|
I have a 3/4 in door of my truck so I can crack the lines when my pump goes dry from time to time on the track. are we talking different lines, or what? Just trying to make sense of it.
