Hi Micheal, I went to p&p trying to find one the other day, the guy said he'll charge $30, but I couldn't find any car that had them! He suggested Mazda vans, but on all that I've searched came with a mechanical pump, except I've found one on a Fiat, but it looks like it's 20 years old! I didn't have time to search anymore as they are closing, but you can get these brand new for about $70-80 from some places..
