My 1997 Jeep Wrangler had a problem starting, I would have to hit the key twice to get it running. Even if I stopped for a second at 711 to get a soda. :/
The problem lies int he pump, that’s in the tank. It has a check valve that keeps fuel from draining back into the tank when the Jeep is off. But, the pump is good. So didn’t want to spend the money of replacing it, I just delt with the hard starting.
But i ended up getting sick of that! So i started a mission to make my own “in line” check valve. I went to my local Ace Hardware, and started looking at some brass fittings. I grabbed some part, went home, put it together and BABAM!!!! it works like a CHAMP!!!
This is not a fix, its just a bandaid! One day the pump will die, that’s when I will replace it.
2x – 5/16″ compression to 1/4″ npt
1x – 1/4″ npt to 1/4″ npt barrel
1x – 1/4″ chrome ball bearing
1x – 1 1/2″ spring. *must cover the ball, but not spring out when installed.
1x – yellow teflon pipe tape (DO NOT USE WHITE TEFLON TAPE)
Small tubing cutter for fuel line
The ideas is NOT to have a ton of pressure on the spring and ball, you barely need any at all. You are just helping your fuel system. To much pressure on the spring and the pump wont get enough fuel to the fuel rail.
The setup is completely reversible! Simply take out the spring and ball, and use the compression fittings to link the fuel line together.
I have been looking into DIY 3d printing for some time now. I have even went as far as to gather a few parts here and there over the past year. But now I have a real need for one, so I have decided to pull the trigger and get it done!
Originally I was looking into making a ORD BOT style of printer. The cost of the wheel bearings and the MakerSlide t-slot materials was going to cost to much. That’s why I have been putting off the project for this long.
In mid 2012 the Rostock Delta Printer was developed. http://reprap.org/wiki/Rostock The printer featured high speed printing and a very low part count for building it, lower then ORD BOT. Thus I decided to make the Rostock instead.
To save on the overall cost, I sourced all the parts over the internet, rather then buying a complete kit. The only downside to this is that all the part will show up over a 2 week period, and not all at once. I will show case the build in parts, starting with the parts I have on hand.
