Can you drive a Waterman cable driven fuel pump off a MSD distributor ? I can't drive off the oil pump and don't have anything to run a belt off of. I know I can call Waterman tomorrow but just curious about others experience.

Most sprint cars (using a cable driven pump) attach the cable to the power steering pump. See link below.

I'm familiar with the waterman setup but my car has a starter so I have a flexplate in the way on the rear of the engine, we also run manual steering. There is very little little clearence in front of the engine. ??? don't know what to do....

Sounds like another sanctioning body/track promoter who's trying to save... I mean spend your money.
Are you using an injector or carburetor? Do you really need a Waterman pump?
If your running a low cost, low output, or entry level power plant, then the Waterman pump seems like overkill.
Can you run a mechanical pump off the block, or even an electric pump (your car already has a battery)...
Based on the limited detail that you've provided, I would bet your engine will perform better, minus the Waterman pump. Waterman pumps are simply too good for a lot of applications and can actually hurt overall performance.

You are correct with an injector pump being overkill for a carburetor but a stock type pump will not work with the sprint front motorplate. Just got off the phone with MSD and a mechanical tach drive will not drive an injector pump. Waterman has no ideas but to possibly run the cable through the radiator (yikes). I should have built the engine with everything belt drive but I'm already past that..... I'll keep thinking....any ideas appreiciated though.

Check out how they mount the pumps on a Late Model or a Mod to get some ideas

This should clear your motor plate! See links below (make sure you read the overview)

http://www.racepumps.com/New%20Plumbing/Plumbing%209.swf

If not, there are some variations of the front motor plate. Some of them resemble a web and may provide better clearance for a stock appearing mechanical pump.
Good luck!

Thanks for the info, I was familiar with racepumps but some guys I know who tried them couldn't get the pressure to stop slamming back anf forth on the gauge, just a little leery about them although they have a lot of positive feedback on thier site. I'll have to give them a call.

I hope the "race pump" works for you!
See the regulator page; they claim that their regulator is the ONLY regulator that will work with the "race pump".
Perhaps the pressure variation you described was due to the use of an improper regulator or bypass.
I like the plumbing diagram, it looks like a nice setup for your carburetor...
