fuel pump
 

what size fuel pump should i be running on my car, it runs high 10's low 11 seconds but i'm getting a stumble sometimes around the 1/8 mile marker. i'm running a holley blue now do you think it's to small. thanks for your help. mack.

I've ben running the blue forever,1/2 inch line ,as fast as 10.70 and 7000 rpm.

No problems

i'm running 5/8 line from pump to regulator then 1/2 inch from reg to cool can then to carb do you think that's hurting anything.

5/8 what are you using a garden hose,,,,Just kidding.

there are people on here that are more knowledgable than me on this subject,there is a science to it,but I would look at carb or ignition.JMO

lol.. yea i got a deal on the #12 braided hose so i used it.

If it's holding good fuel pressure going through the traps, then it's just fine.

that's something eles i need to know where should you hook the fuel guage up at the regulator after the regulator or what.

carb side of the reg.you cant do anything without knowing the fuel pressure!

I ditched my Holley and chucked in a BG400. Never had a prob in my Camaro.

what kind of fuel pressure you run with your bg400 and camaro.

Ditch the 5/8th line,its too big,on accelleration it may be hindering fuel flow......

WHAT!!!! :shock: :shock: :shock: YOU ARE SOOOOOOOO! WRONG!

when the cars moving forward the fuel may be moving backwards due to the larger size of the hose reducing pressure, but hey, to each their own, 5/8s line on a 10.90 car? new to me.....

blue pump pressure will drop with the 5/8s line,not powerful enough.my last comment,

A 5/8 fuel line running from the back to the front of the car has a lot of fuel in it that under hard acceleration the weight of the fuel will make the fuel pump see more pressure than is at the regulator.
