Just wondering if i need to buy a new fuel pump with the NOS Dry kit?

 

The NOS 5176 kit for the LT1 comes with an inline fuel pump. You should install it. Works fine, assuming your stock intank pump is healthy.

 

I run the same dry kit, just without the inline booster pump. The stock intank pump keeps up, up to a 125-shot, thats about 100 rwhp!
That's with an .059N/.046F jets, 950psi bottle pressure.

So, with the inline pump, you should have no worries...

 

so would i need to use the inline booster pump if i already have a walbro 255lph?

 

with a intank pump you would need the inline untill you max it out. injectors would be some insurance incase your stockers lock up.

 

i have #42 SVO but i will still need the inline NOS pump to boost the fuel pressure up to 80-90 psi. because my walbro isnt designed for high pressure.....
