 |
|
I know of 2 other techniques to eliminate the fuel pump vent clearance problem:
!) From memory..... according to Tom Martin, you may be able to disassemble the fuel pump and re-clock the vent port to a different spot.
2) From www.vincesrocket.com Rather than disassemble the pump so the vent port would clear the firewall, I did the following: the vent was plugged with a pipe plug. I had to trim the bottom of the pipe plug to clear the hose barb. I tapped a hole in the side of the overflow vent and installed a hose barb for the overflow line. Be sure to put a piece of foam inside the vent port while drilling and tapping to keep the chips out of the pump. And clean out all of the foam and chips before the final assembly... duh. I used JB Weld to seal/glue the hose barb in place since there is no way to safety it and my tapped hole was just a little loose. Not shown in the picture was the final grinding off of the pipe plug so that no excess metal was left sticking out. Here's a photo: http://www.vincesrocket.com/2004-03-30/fuel%20pump%20vent%20mod.jpg

Thanks, Vince! I'll put those two tricks in my quiver. Now, I'm wondering if I could just tap the hose plug for a barb after drilling a small hole into the pump end of the plug... That may give me enough clearance and I would have the chips and shavings on the outside the whole while.
I appreciate your posts and your website. They have been great sources of information over the past several months!

Randy,
All good ideas. On my HR2 I made a small indentation in the firewall shelf to provide the clearance for the fitting. Worked great lasts a long time...

Smokey,
Thanks! I wish I had a the room, now but it's all together. Not an option I am afraid.
Re Viper flyng, me too... 24 years of bliss! (well, except for the 4 years in the 5-sided puzzle palace!).
Hope to fly with you some day...
