I use the red Edelbrock one to feed my dual quads and I've never had any starvation issues at the track or anyting. I actually use one for siphoning gas back and forth with some long leads and some hoses...
glad you said that. I actually had the red edelbrock pump in my hand today at O'reilly's (60 bucks) looking at it. Did you run a return on your car? Or just have it end at the carbs? the package said 5-7 psi, do you run a regulator?? Thanks
