Making fitting for a Bosch 044 pump to accept intank style.
 

Well after looking around for an intank filter to just bolt on for my new 044 , I decided to not pay 50$ plus shipping for one. So I decided to make something else work.

What I did is take an m18x1.5 to AN fitting and machined down the AN side to 0.730" to very tightly fit on the filter which has a hole size of .734". The filter has 2 tab on it that put pressure on the fitting and stop it from slipping out. I machined a small groove on the fitting for those tabs to pretty much clip in there. Also the top tapers about 2 degrees to give it a really snug finish. Lastly I opened up the hole size to 12.5mm, not sure what it was before, but that is what the outlet size on the filter seems to be. All of this only netted me about 20$ and only took about 30 minutes to make it work, and I can always just order that same filter. Prying off the filter does require some patience and delicate movements but it does come out.

The filter that I used is circular in shape (Delphi # FS0015), with the fitting slightly offset. Its the best one that I could find to make it work properly and not adding too much height. The diameter of the filter is just slightly bigger than the pump itself.

Lastly I needed to go from m12x1.5 on the outlet side of the pump to a 3/8" barb fitting, but nobody seemed to carry one, and if I were to order one it would of been over 30$ for some stupid reason. So i bought a m12 to1/4" barb, and a 1/4" NPT to 3/8" barb fitting. Cost of both was about 5$. I turned the 1/4" barb end to snug fit into the 3/8" fitting and took the threaded part off the NPT side for welding them first. I did 2 beads, one going clock wise and another counter clock wise. I welded them while being pushed into a vise to try and reduce movement. Then it was back on the lathe for that piece. I shortened the barb a bit to make sure it fits in the tank easier. After that It was time to re-drill the inside to get rid of the 1/4" barb and make it smooth all on the inside. I used a 17/64th drill bit as it seemed to be the best suited.

Anyways here's the pictures from it all done up. Let me know what you guys think.
