Fuel system question.

[cobra-bit]

I’m currently running a BBK 255lph fuel pump with a t-rex pusher, #42 injectors and stock lines and rails with a supercharged car.

Up to what rwhp mark would I need to upgrade my current fuel system including lines?

Thanks,

Your can take that setup to 500rwhp somewhat safely, just have to watch it.

I’ve heard so many different stories but what you’re telling me is the same thing my shop is telling me, I just wanted to confirm.

….Jason, I’ll just email you direct whenever I have a question that needs to be validated. :thumbsup: thanks again for your help.

I've heard lots of stories/opinions on this one too. Anything past 500rwhp, I'd be looking at lines, rails, etc. Just my 2 cents.

X2 - I believe rails are the weakest link.

so at 500rwhp how long would the stock block hold up for?

It's all in the tune and how many RPM's you spin. It could last a week or years.

Exactly what I was going to say.
