Fuel Injection

Unread postAuthor: SpudBlaster15 » Sun Dec 17, 2006 12:19 am

Well, I finally got around to building a fuel meter, and I dont know why I didnt build one earlier. The performance is great. I am using Mapp gas, and it seems to work best at around 60 psi.

Image

I always hear people talking about the meter to gun connection, and how it has a high chance of blowing out. I made sure that this could not happen by using a 1/2" to 3/4" bushing on the threads as a nut. The assembly is *really* solid and I see absolutely no way for it to possibly blow out.

Image

Let me know what you think.

Hey SpudBlast !!

Very cool... an "Uzi" style !! I LIKE !!!!!!!! I've got a lot of catching up to do to get as elaborate as you... You're in a much higher-league than I am, but am still impressed with the performance of my gun with minimal investment.

I have some short video clips once I figure out how to attach... or will this forum accept them?? Please advise.

Thanks SB.

Thanks for the compliments!

As for the video clips, I suggest creating an account on http://www.photobucket.com and uploading them there. Then you can copy and paste the link into your post.

How is it Uzi like?
Its big, The meter wouldn't blow out since only a small amount pressure is placed on it.Especially withe that nut, reminds me to pick up on for my gun.

I just mean't "Uzi-like" because of it's look... since I can't see the rest of the barrel... I'm assuming it's got at least a 3 foot barrel on it. Cool nonetheless.

THanks Spud,

I should've known you'd have a longer barrel on the thing... well over 3 feet !! I mean, what would be the point of having a sawed-off ?? You'd have no control over aim or trajectory !! I think I'm gonna seriously start thinking propane now that I've seen some other guns.
