Thanks for the introduction Aaron...
yep.. I'm the harper.. carbs do use a return line if they are done right and done for maximum HP... and heck wouldn't it be worth another 5$ to do something right and possibly better. (go to a race track and see how the top carb guys are plumbed...) regarding you fuel line dilema.. I think you'll be fine. why don't you buy a fuel pressure gauge and then "know" for certain. you can plumb the regulator either before or after and use the guage accordingly. you should be fine unless you have a Monster!!! pump on it. I've seen a 906 motor (twin plug 2.0/6L with 46 carbs) run just fine on a 15psi Holley pump with a regulator. If your pump is bigger than that I'd recommend down sizing your pump. brant |
