I could say the same about rockets. I can dream anyway. In the dim reaches of my long term memory, I believe this is a long standing problem. The RV 4 has a clearance problem which sounds like yours to me. If so, Van's has a $9.50 solution. It is: Part Number = F OVERFLOW PLUG 1/8" Here is a link to the catalog: http://vansaircraft.com/cgi-bin/store.cgi?ident=1355067275-394-210&browse=engines&product=overflow-fitting Hope this helps.

Stuart's solution is certainly the most elegant, but simply removing the fitting would seem to work also, as there should be no fuel coming out of the port if all is well inside the fuel pump. Seems like the only reason to have the drain line is to make it easier to ID the problem and I am sure the FAA required it for certification. > > Thanks, > Randy > > > > > Read this topic online here: > > http://forums.matronics.com/viewtopic.php?p=390080#390080 > > > > > > > > > > ________________________________ Message 2 _____________________________________ Time: 07:47:26 AM PST US Subject: Rocket-List: fuel pump vent clearance From: Vince Frazier 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 Vince Frazier Flyboy Accessories www.flyboyaccessories.com ________________________________ Message 3 _____________________________________ Time: 08:12:53 AM PST US From: Noel Rodman Subject: RE: Rocket-List: Re: HRII Fuel Pump Vent Clearance Denis=2CThat was great=2C I will be laughing all day about that one=2C Than ks. > Subject: Re: Rocket-List: Re: HRII Fuel Pump Vent Clearance > From: denis.walsh@comcast.net > Date: Sun=2C 9 Dec 2012 08:42:21 -0700 > To: rocket-list@matronics.com > > > Hey Randy > > I am not a viper pilot but I play one in my dreams frequently.

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!

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...
