OLD STYLE VACUUM PUMP

The Old Style Diaphragm Vacuum Pump category includes parts specifically designed for 1993 and earlier engines that feature a diaphragm style vacuum pump. These pumps may not offer the same efficiency as the later style pumps commonly found in newer models, making them less ideal for certain conversions and upgrades.

One common issue with these older vacuum pumps is the compatibility with electronically controlled transmissions. Throttle position sensors for these pumps can be difficult to find, but alternative sensor options are available to help address this challenge. Additionally, the A/C compressor may pose a problem, as it is often longer than the 1994 - 1998 versions and may require a different mounting bracket.

However, it is worth noting that the vacuum pump and power steering mounting bracket are interchangeable between the older and newer style pumps. In some cases, the 1993 pumps and brackets may even be identical to the more conversion-friendly 1994 - 1998 versions.

Overall, the Old Style Diaphragm Vacuum Pump category offers a range of parts and solutions for enthusiasts and mechanics working with older engines that feature diaphragm style vacuum pumps. By exploring the options available in this category, users can find the components needed to overcome compatibility challenges and ensure a successful conversion or upgrade project.
