Fuel pump? Fuel pump wiring? Fuel filter?.... That's where I would start

I just replaced the fuel pressure sensor still same issue. I can hear the pump prime but it's not what I'm used to hearing. Now has a high pitch when it primes

[solo5057]

sounds like your fuel pump is bad, or weak.

When was the last time you changed the fuel filter?

Non submersible hose? Definitely wrong clamps to be using.

Trans oil cooler lines. Those clamps came with the kit. Which clamp should I be using? I'm a few mins from putting everything back together

STAINLESS FUEL LINE INJECTION HOSE CLAMP

Looke like you got it figured out but you need high pressure hose clamps and tubing / hose designed for fuel injection applications. See pic for clamps you can get them over the counter at pretty much any parts place, but in your case it looks like the hose let you down.

Thanks fellas going to get these clamps now

You need to use SAE30R10 submersible fuel hose. That is probably the reason it blew.

I'll purchase those and install when I upgrade the fuel system. Thanks for the advice
