Thank you!!!

M1123- while driving, my Tachometer went dead, then looked down at voltage gauge and it went from green to in the yellow. Any advice where to start to find out what part is bad? All connections are clean and tight.

Thanks for finally answering the question of what Armanda springs!! 👍

Hello!! I changed out the Lift Pump this afternoon and OMG!!! What a difference!! Like going from a 6 cylinder to a BBC!!! I can get up to 65mph so much faster, like a driving a normal vehicle!! Everything went super easy. Took me maybe 2hrs in the 30-degree temps outside. Thanks again for all...

Mogman, THANK YOU very MUCH for all this information, man!!!! I owe you a cold beer!!! lol

Ok, i should be able to see this Lift Pump ROD? and whether or not it's installed correctly, right? Last thing i want to do is break something else, lol....i searched u-tube on humvee Lift Pump installation and nothing coming up. I'd rather be prepared and spare any guessing.

Any simple way of checking the check valves? I'll change out the Lift Pump and try opening the fuel filter drain bleeder and see IF it stalls out, hopefully fuel will bleed out....Thanks again!!!

Ok, gotcha!! That helps a lot man!! Thanks again! My Lift Pump should be here on Thursday. I guess it's still ok to drive if needed as i have been all this time, lol

:oops: oh boy!! I think i'm understanding this now. The IP is supplying the fuel and not the Lift Pump? Gotcha....Thank you so much man!!

I have NOT removed any check valves. She starts every time and runs fine. Doesn't seem to be starving from fuel. Sorry, what is the "IP" ? Thanks for explaining this. I did order a Lift Pump and should be in this week. It seems like a normal Fuel Pump as far as changing it out.....

I never looked at the date, lol.....besides, no one ever answered the question with a fix, and it just happened to me, so i figured i'd share my fix in case someone else does a search like i did and this same thread pops up, this time it will possibly help someone. :D

That's a nice set up. Where did you tie into the fuel line? before the injector pump? Great idea!!!

I'm confused here on the bad "Lift Pump", IF the vehicle is running and driving around, but you bleed the fuel filter drain valve and it shuts off, how is the LIFT PUMP bad? It has been running until i hit the drain valve. Hope that makes sense......

No, you got air in the system. Remove dog house and crack the injector on passenger side of the head have someone crank it while you crack open the injector nut till you see fuel coming out. It should start back up after you do this!

What shocks are these??
