Has to be the source.

Have you considered getting your existing pump rebuilt? Talk to Randy at http://www.stangerssite.com/

Kind of Jeff. I think I'm too impatient to wait while it's gone - plus pay the shipping costs, etc.

A new pump will fix the problem. The main problem you will have with a new pump, though, is finding a "correct one". I have yet to find one. The original pumps on the Mustangs has the return line bent at a 90 degree angle, downward. None of the replacement pumps I've found do ... they're almost straight and can cause problems clearing headers, and oil pressure sending units.

You can bend the replacement ones a little, but there's not enough length on it to get a tube bender on it, so it's extremely hard to bend it without kinking it.

You also have to make sure you get the '70/later pump. It is not the same as the '69/earlier pump.

You can increase the size of the pulley to slow it down. I have underdrive pullies on my crank and water pump, and a larger than stock chrome pully on my PS pump. This gives less assist, and makes the steering a lot better, IMHO. The steering in my '69 has always felt better than it did in my daughter's old '69, or in her current '67. The main difference is just the size of the pulley that I'm using.

I am using the replacement pump, and bent the return line as much as I could. It works with full length headers, but it's tight. I mostly mention this so you're aware that you won't have the room that you do now.

BTW, telfon tape will probably not seal it. Like Dave said, it's probably leaking between the pump and the case. The only way to fix it is to replace that seal on the inside of the case, and the easiest way to do that is with a replacement pump.

Thanks John. And do you know the diameter of your larger than stock PS pulley?

if you want the stock look you could use a 70 Boss 302 pulley that I understand is a larger one, it is reproduced. someone correct me if wrong

No, but I'll measure it tonight and let you know.

I had this same problem, I ended up putting a waser behind the nut on the back of the pump and problem solved.

What type of washer??

02Lightning · « **Reply #34 on:** October, 22, 2009, 10:44:54 AM »

I think I just used a plain flat washer on it, what ever will fit. I think what was happening was the nut didn’t have enough surface area to seal the housing to the sealing surface inside the pump and the washer solved it.
