ok I got all the stuff except for the air chuck.
15lb psi gauge $9 amazon
copper pipe local industrial plumber shop $19
air chuck cant be more than 3-4 bucks
i still need to cut the long pipe, i went a size bigger to help seal better, if you look at my old one you will see blak tape
i put on it to fit better.
i am gonna build another one that should cost $15 out of pvc. stay tuned.
all i need to do is get it solder up, i dont know how to do that, so gotta get my dads help.
REM, so I tried measuring the plug attachment and it didn't fit any of the threads I had on the measuring tool. Turns out spark plug threads are a bit off from regular bolt threads. I imagine this allows the spark plug to get a tighter seal the more you screw it in? All the attachments I needed came with the pressure gauge I got from Harbor Freight, and in the contents they just list it as 1/4”-18 (male) x 1/8” - 27 (female) and the part that screws into that is listed as 1/8”-27 (male) x 7/32” (barbed). Look at the picture on their website to get a better idea, i posted the link earlier.
GrkGuy, looks real good, but just seems a bit complicated. Why didn't you just get the pressure tester from HB's website? Would have saved you all the trouble with fittings, soldering, etc. and shipping is $7 i believe.
I agree about the plugs though, they will be different depending on your setup so everyone should find what works best. I just took my carb and my exhaust flange to home depot and had plugs for both within 15 min.
Pic of the one I made I didnt take pics of the freeze plugs but this is the tester I made.
