Upgrade hpop on not

[jjaggard]

I have an early 99 f350 with stock injectors and turbo. I have ford ais intake and 4" mbrp exhaust. Would it Benefit me to upgrade from stock 15 to t500 terminator? Or even an adrenaline? I use for daily driving but also pull a 30' 7500lb trailer for camping? Has a hard time up hills and keeping it at 70 on highway. Any help on this matter would be greatly appreciated

You need to test your HPOP to see what condition its in. Dont just blindly replace it.

I'd check your fuel pressure first and replace the FPR. $70 is better than $700 and i bet thats where you find some of your lost power. After that, look for boost leaks and up pipe leaks

And even before spending the $700 on a HPOP I would save a bit more and just throw a set of stage 1 or AC code injectors...

but as was said before, check the ICP pressures and duty cycles, pump may be fine.

ok, but wouldn't a hpop upgrade help protect his engine regardless, maybe just do it not quite to the ones mentioned but to a superduty 2000-2003? less expensive route and provide better lube for that baby? have not done it yet to mine either but not towing quite that much yet and still considering it for a upgrade.

would also recommend either a program or a chip for the towing bro, world of diff as i have 4in tubo back and open air intake was only mods before, so sounds like we are in the same field.

If he doesnt need one he doesnt need one. A 15* HPOP will feed stock AB injectors fine, so long as its not worn out.

Without ICP levels and duty cycles we dont know.

hpop has nothin to do with lubrication

Wow thanks. I wasn't expecting so many responces so quick. Last post I did was a month ago and still no responces. So this is great thanks. I have no access to scanner, but I have to build a fuel pressure gauge will get back with fuel pressure this weekend. Any other test I could do would help thanks. Also if anyone has any ideas on my last post about truck sputtering only when warm. That would also be appreciated.

Take a look at AutoEnginuity. Its going to cost around $350 but it will save you hours and hours of heartache and head scratching. I wouldnt diagnose a 7.3 without one (or an equivalent).

The one thing it cant do is indicate fuel pressure. Get yourself a gauge. Honestly, if the truck has over 100k miles, I'd replace the FPR ($70). Do NOT shim it. Do not put a BB in the thing - replace it.

MEH....

I have put over 250-280k on everyone of my 6 powerstrokes over the years...

Never once replaced a FPR spring. Not once.

Its not a part I worry about, if your making 50-60psi or better leave it alone. If your making 50 or so I would shim it... but thats just me, a guy who drives the piss out of these trucks.
