HPOP is only moving 150psi.

 

If the HPOP is only making 150psi, then its an IPR issue, Injector issue or HPO pump issue.

Whats the duty cycle?

Buzz test?

 

dunno. Guy at the shop I sent it to told me that. he's gonna have more info/pricing tomorrow AM.

 

Dont let him replace parts without checking back...

 

Duty cycle was 65.
he did the buzz test.

he wants $1500 to do it.
$750 for the pump
$35 for the gasket
$260 for the IPR.
he said "we always repalce the IPR when we replace the pump"

 

Before he replaces anything I would clean the IPR...

If that doesnt work then we will go from there.

If you need a new pump, and thats a big if... $750 bucks is getting bent over... As is $260 for an IPR... The gasket is reusable, I have the same gasket from 5 different motors.

Here is an upgraded pump that is 15-20% larger then the factory pump, for less then that...

Stealth Industries LLC. Stealth Pumps

There is IMHO the best pump on the market... Will power up to 300cc injectors without issue.

Way more then you need, but its also only $150 more then your guy is trying to bend you over for. It also has a lifetime warranty.

 

that's pretty much where I am at.
I already cleaned the IPR prior to sending to the shop.
the truck is a DD for the most part, so I doubt I need larger pump... probably be fine with a reman'd one.

I just don't have the diagnostic tools to see what was going on. But I'm not afraid to get my hands dirty...

... Here is another pump... RiffRaff diesel has both the bosch pump...

Or the modded TE pump... I'm not a fan of the TE company, but the price is pretty damn good... and at least your buying it from Clay.

Riffraff Diesel: Terminator T500 HPOP

 

You dont... It still could be an injector issue. Without doing a leak down test, and isolating the HPOP from the rails you just dont know for sure....

I know I am overloading you with links and such, but all this stuff is in the master sticky at the top of this page.

Its good to get your hands dirty, and as scary as these 7.3's seem, there pretty damn easy to figure out with the right tools.
