2. Use a tall metallic can with a screw-on lid. Mount the glow plug in the side down at bottom. And the hoses high up in side (mine requires oil level be so high that air flow can spit a little oil out of it and when oil level gets low, mine requires a little jiggle to splash oil onto plug). 3. Install a check valve in the hose to insure nothing can flow backward up the hose to your glow plug. 4. A pressure reg. might be a nice touch, but shouldn't be required for vacuum-leak-only use since CFM is so low on one of those pumps. 5. A water trap after can in hose might be a nice touch too to stop any oil-spitting. 6. Power the glow plug off of the pump's built-in switch. It is easy to forget if glow plug is hot at all times when battery is hooked up. This ends up being a neat little package. Also don't forget this can be used often in pinpointing engine oil leaks too and exhaust leaks with the right tail pipe adapter.I have recently upgraded it to see the latest details check out my website.
