What belt driven pump

I need to know what belt driven pump you are using I looking at BLP AND AEROMOTIVE I am going to run the bypass regulator with a return line double adjustable. Blp is fixed at low rpm.AND adjust after idle the automotive is adjustable on both I think ??? I am running on alcohol thanks for any information. THANKS

I’m currently running a Waterman pump, but have run Aeromotive without issue. Reason for change was that I went to cable driven pump.

Waterman should be able to convert to cable.

I run a waterman cable drive pump

I have the APD on my dragster. 2-3 lbs at idle then goes up to 6-7 with rpm. Only downside is you have to fill the bowls if you change jets or run out of fuel...

What I meant was, I switched from Aeromotive to Waterman, as I wanted to run cable drive
