HPO Resivor darining

OBS-Addiction97 · May 9, 2014

Went to start my truck today and it wouldn't start. Looked in the hpop res and it was empty so I filled it, truck fired. I just got done changing my LPOP because I had a new one sitting here. Now it's taking a extended time to crank when it sits for more than a few minutes. I really hope this isn't my brand new POS SRP 1.1 causing this with under 3k. Any other ideas before I pull this hpop and burn it?

I had the same issues with my stock pump on my e99 superduty after I resealed the whole pump and replaced the non serviceable plug. I could not build pressure at all and saw my hpop resovoir draining back replaced my pump with a new adrenaline and solved the starting issues. its possible that if you removed the hpop resovoir and didn't replace the oring seal on the bottom that you might have a air leak or bad gasket.

im still new 2 these 7.3 engines and I am learing as I am going. bought a sweet low mileage truck that's becoming a money pit though.

I have a funny feeling that if I put my stock 15* pump back on with over a quarter million miles my problems will disappear. Sad part is a forum member sold me this pump saying it was "brand new" not a pump that already failed and Gary had rebuilt again. Freking amazing.

maybe he was being truthful? its not like these pumps are reliable or anything...

I don't understand how so many people have problems with these pumps and they still are being bought? If I you have the money and the HPOP is your problem order a HB Jr. they haven't been seeing many problems as far as I've heard. if I were you I'd check the plug in the block behind the timing cover and make sure the spring and check ball are ok.

Nothing against dyno proven but the same story was being weaved about the stealth. And as pumps in a stock case go it was the alpha male(srp1.1) but the failures are too high.

Wasn't trying to put them on a pedestal just curious as to why anyone at this point in time would buy an SRP1.1 maybe it's just recently but all I've read are problems with the pumps?

That guy bought his pump from a member who had it repaired and sold on the forum after the fact. Then the thread's showed up and then people who had identical symptoms and shortly after, failures were posting their experiences. Right or wrong.

One shop owner had his fail going out to rescue a broken towrig headed to dpc. He pulled up to unhook the dead towrig and when he hit the key it did the normal no hot start srp1.1 failure. Build icp to around 300 psi and no more. He switched out the pump and the issues went elsewhere too.

Ive been told to send mine in as others have only to recreate the failure again.

Sorry to hear that I have been lucky I went from an adrenaline straight to BTS big oil. Big money but I haven't had a single problem with the dual pump setup. Must be hard for you guys who aren't looking for duals but need bigger than stock oil.

mine works great.
other then duals you arent going to run big injectors with any other pump available.

this turned in to another bash thread with no diagnosing to point to the pump.
every thread I see on goole says the check valve is the usual culprit for a rez draining issue, second is failing to seal it on install.
when it has oil in the rez does it build pressure?

Ive been talking to him and the things that are happening are inline with the other pumps I know of that did fail. Theres no way EVERY truck with an srp1.1 that wont build icp has a bad lpop or a bad injector dumping icp. The op has brand new injectors from pis that would run just fine on a weaker 15° pump.

Theres a lot going on behind the stuff you see that is posted on the forum mj. People are being careful about accusing the pumps so keep that in mind.

Why is every srp "failure" thread exhibiting the same symptoms? Theres two certainties in these threads: the first is the symptoms are all the same second you, mj, come in here to lay down for Gary and have no ***kin clue that people have talked behind the forum posts and its probably better that people are filtering a bit.

Its a bad situation and unless you KNOW the pumps ARENT bad you should probably mind your p's and q's.

What year is the truck? 94-95 had a diff pump than 96-97. If you put a 96 pump in a earlier model you will have your same symptoms.

TyCorr you are almost the last person I would ask for HPOP help.

i dont see anywhere in this thread where the OP said 'it dont build pressure' (which is the main SYMPTOM of a dead pump)
he said 'the rez is empty'

what does the troubleshooting say for an empty rez? not 'blame HPOP'. that is TyCorr's addition to the issue.
troubleshoot the issue and not some weird agenda.
I would be worried that the empty rez killed the hpop by dry cranking

I dont 'lay down for Gary'. I have never spoken to Gary in my life and I owe him nothing at all. chances are his fineprint has my pump out of warrantee before I even got it installed.

After replacing my lpop. Had trouble with same thing long cranks. I took lpop apart and filled with grease and problem solved. Two years later and starts on first crank. How long has truck ran since lpop.

Is res refilling if you crank when its low? If its draining while sitting, easy to figure out if its the pump or not.

Procedure is this: pull drivers side hpop line from the head and zip tie it so the open end is ABOVE the res. Let it sit over night. If res is still full you have bad injector o ring somewhere on drivers bank. If res is still drained/low, reconnect drivers line and repeat procedure with passenger side line. If res doesnt drains down, bad o ring on passenger side. If res still drains then pump is internally leaking down. To confirm disconnect both lines, tie them up with open ends above res and check in the morning.

If it is not injector o rings, then it is either pump or something in the front cover.

Hope this helps narrow it down.

Thanks for all the replys. I haven't had a chance to mess with my truck in a few days. Ill have a look at in tomorrow.

Thats fine dikkweed. Id be the last person to give you advice. Ive helped tons of people and even had it be something that and IDE said wasnt the problem actually be the problem.

My comments were more aimed at the op hence my comments about you. That went right over your head obviously.

If you dont have an agenda then why are you the person trying to convince everyone the pumps arent causing issues.

Back to the same old bs as the other thread.

Whatever, you "help" someone and Ill be impressed.

You'd have to crank the truck until the batteries died and even then it wouldnt ruin the pump. The pump would still have oil in it. Who would crank it that much anyway if it wasnt firing right off? Pretty obvious ya boob.

TyCorr · May 11, 2014

And also mj, so as not to rely on your reading comprehension which is completely non-***king-existent, show me where I blamed the pump in here. Since I havent and thats what you are accusing me of, I wanna see how you weaved it. Its bs, we both know that, but I want to see how you fabricated it.

You better be careful if youre gonna start making shti up involving me just to try to make yourself or a part look better.

Ill repeat, when you do actually take on the act of helpung diagnose the issue ill be impressed but so far all youve done is try to convince him it can NOT be his pump. Whether it is or not.
