Blown hpop line... Again
Hey guys so y'all might remember me blowing a line about two months ago or so. It happened again.
This time though, it was the pressure that blew the line. What pressure will I be seeing on the line going from the hpop to the head?? The one I had made should have been good to 3000psi... I thought our trucks only put out around 2900-3000 wot...
Stock hpop by the way.

Not sure about a stock pump but my terminator will regularly run 3300. It would be best to have some live data on what your trucks putting out. Also I think I would find a hose rated for at least 4k. I would rather have a little extra than always pushing the limits

I'll post a picture of the blown line when I get a chance. Also, does the line have to be steel braided?? The guy at Napa said his line wouldn't be a permanent solution because it was a rubber hose.

The first replacement (blown today) was a stainless braided for 3000. The one I got today is rubber up to 6000. But the guy at Napa said this 6000rubber hose wasn't going to hold up in the heated environment of the engine bay.

Hydro hose have two different ratting. You have a continuous psi rating and a burst rating.
If 3000psi was the burst rating then the continuous is around 1800-2000psi.
When having lines built you want to do a minimum of 4000psi continuous and have them done at a hydro shop. Not the guy at the local auto parts store.
Look at it this way. A tire rated for 65psi will probably hold 80psi but when you start working it how long will it last ?

Well it's looking like I'm going to have to shell out the big bucks... No hydraulic shop in town has anything steel braided rated for anything over 3k.. Since I plan on doing the t500 at some point in the future, I'm not thinking those are going to work. Oh well. I tried to go cheap and look where it got me.
