I have a walbro in tank already, a second one ready to drop in to make it two walbros, one to run off a hobbs switch.
wondering if the stock fuel rails and lines handle 700rwhp? this is on boost.

my car did 730 at 5900rpm but my injectors were at 150% duty cycle my car is a auto and I was on a mustang dyno.Iam changing my fuel system,hope this helps.

You will start to get a sizable pressure drop in the system due to the line restriction & rear mount regulator. It is usually pretty good up to approx 700rwhp, then the drop gets more severe.

OP sorry bout the thread hijack! didn't want to start a new thread for this question....

I am working on a Budget boost 5.3 project shooting for 550-600hp, and will be running 50 meth/50 water injection....

I currently have a single walbro pump and stock lines and rails....

Can i just add another intank walbro, new fuel line, and keep the stock fuel rail? I am on a very strict budget....

Thanks,

Blaine

your stock lines and rails should be fine.60#injectors?

I personally do not see the point in risking it. At this level, I would swap 'em out....

But then again, I don't like holes in my pistons or popped HG's either....

definetly choking the car on fuel id just change em out, cheap insurance.

yeah, i think i will take the advise of those suggesting to swap them out. i have had bad experiences with them on my other cars not fitting correctly, leaking or just simply a pain to gathering all the correct parts for installation...wrong part or extra parts = wasted money.
i will call one of the vendors during the week for complete

Are you open today?

Lonnie is the man, I have not delt with him directly myself (yet) but I helped a good friend of mine install Lonnies twin pump GTO setup in his car and it was perfect. Pretty sure you could call him at 11pm and he would answer the phone to help you out if you were having problems.

lines are fine, but you will be pushing the 60's.

Yes I have 60lbs injectors, if that's what you are referring to.

I would definitely go with the Lonnies kit if you want a direct "bolt-on" kit.

I'm making 600 rwhp w/ an auto with stock feed line. I'm using aftermarket rails, a rail mount regulator and the evap line for the return. It's a cheap alternative to a full fuel system, and it will support a lot of power.

i WILL be making 600-630rwhp and i've got Nasty's stage 2 street kit....Walbro 340 pump in tank with -6 feed line. i'll use the stock feed line as a return. better safe than sorry, especially on boosted/N2O motors....
