good deal on a vacuum and fuel pressure gauge for testing  By  scooter (Read 706 times)

I have been reading some posts here about fuel pumps, fuel pressure, and vacuum. It seems to me that a smart mechanic would want to know what's going on in their motor, and not just guess, so I'm getting myself a vacuum and fuel pressure gauge. 

I realize these are one cylinder engines, and that the use of these gauges may be limited for us, but I'd like to know things like, when the engine bogs out at wot, what is the vacuum pressure and what is the fuel pressure at the time? Also, some reading indicates that a vacuum tester may be able to tell me about my valves. It seems like a useful tool. 

I wrote this because I passed up a good deal.

I bit the bullet and bought this unit for $20 because it's new, has a huge 3-1/2" dial, and a case to keep it clean and safe:

But if someone needs one of these, this one, albeit used, is made in the USA and is only $8 with shipping and you'll have it in about a week or so:

Here's another one Harbor Freight for only $15:

I don't know how much they sell for at walmart or your local parts store, but these seem like good prices to me.
