Posted: Mon Feb 01, 2010 5:49 am Post subject: Fuel Filter Service - Access Panel

I was thinking about how difficult it is to service the fuel filter.  First, just to get at it there is a pile of work in removing the tunnel cover.  Some have split the tunnel cover so it isn't necessary to remove the entire cover to inspect the tunnel, great idea, for those still building this should be considered.  Others have installed an access panel in the side of the tunnel in the foot well.  This allows easier access to the fuel filter and fuel pump.  One of the things I really dislike about servicing the fuel filter is that you have to break the fuel lines, and this causes some fuel to spill.  Add insulation to soak up the fuel and you have a recipe for disaster, so you need to use a box of rags to keep the fuel from getting all over the place. 

 

So here is what I was thinking, I wished that when we built the airplane we would have installed an access panel on the bottom of the airplane that we could have reached up through to get at the fuel filter.  This would have been much easier during construction....  An alternative would be to install a second fuel filter, and place both filters at the tank exits under the wing walk access panel. 

 

I post this simply to get those who are still building to think about how they will service the fuel filter.  Not sure how we will modify our airplane to simplify the task.

It's not that big of a deal to take it out, and you need to inspect inside the tunnel anyway at each annual.



Run the engine dry to check that the shut-off valve works, then a couple of paper towels soak up any residual (I put no insulation in my tunnel for just that reason.....did not want anything to soak up fuel should there be a leak or spill in there......

I wouldn't mess with cutting access panels in the floor......at least not before checking with Van's on what it might do to structural strength....

Posted: Mon Feb 01, 2010 6:10 am Post subject: Fuel Filter Service - Access Panel

I just did this yesterday...removed the tunnel cover and

disassembled the fuel filter.  I was contemplating doing

a side access door like Scott to get to the filter. I think

that access door could be really handy in accessing the filter

to get tools in there.  But, at the same time, even if you

have the door I don't think that makes it a great idea to

do any filter removal without the tunnel cover off.

I spilled plenty of fuel in that tunnel area and had to

wipe it up as you noted.  I wouldn't want to completely do the

job through a side panel unless I knew I could get it

all 100% cleaned.  So I think that unless there were a

bottom access panel as you noted, there isn't really

a good way to service the filter without removing

the tunnel cover completely, and also removing that SCAT

tube for better access.  A side panel removal would

add to easier access.



But, when all is said and done, I think removal of the

entire tunnel cover is probably something you should all

be doing once a year anyway.  And I mean the entire tunnel

cover back through the rear seats.  It's the only way

you'll be able to inspect and lubricate the control rod

ends.  It will still be a pain in the butt, but if it only

comes once a year during annual time then it's not much

worth complaining about....it's easier to annual an RV-10

than it is some of those other certified planes.

I’m not sure if it’s possible, but I’ve been thinking of adding one filter at each wing root.    

   

I like the simplified access to the filter, but I also like the idea of having one fuel filter dedicated to each tank.  This way if a filter should get blocked, I can flip to the other tank and access some fuel there.

If a builder decides to start cutting extra holes in the skin,  I would advise getting a structural engineer's analysis of the  proposal.

I did insulate the tunnel, but only the side walls.

I don't think it does anything worthwhile to do the

sidewalls either. The forward firewall, sure.

And then the SCAT tube wrapped with insulation.

That would be all I'd do if I were doing it again.

My sidewall insulation doesn't go all the way to the

floor though so fuel spilling and soaking isn't

going to soak into it.

Is there any particular reason the filter needs to be in the tunnel? 

Anyone considered relocating to front side of firewall?

I think under the seats would be an awesome location except

for one thing.....when you disconnect the lines, with

no valve to shut off, you're going to dump fuel all

over the place.  So that would tempt you to add shutoffs

to each tank in front of the filter....and then that's

another point of leak/failure.  Maybe with the right

valves I'd consider putting one filter per wing and

putting them under the seats.  Not sure if it's worth

the hassle though once you're flying.

Like I said, I am not sure how we will handle this, or if we will even make a mod.  I just wanted to give those still building a chance to think about a possible mod while it was still fairly simple to implement.  Knowing what I know now, I can promise that if we had known about this we would have done something (again not sure what) during construction.

Each tank , IIRC, already has a filter screen. Additionally  one can see the fuel flows for various power settings on the EFIS, so some  indication of a future problem may be evident. Lastly drain/flush  the main  tanks

after the build process. Mine were QB tanks but still had residual pieces of proseal which I flushed before sending any fuel to the filter.

I was dreading taking the fuel filter out during the first condition  

inspection back in November. It was a PITA, but not as bad as I had  

feared. Some certified airplanes have an access panel on the belly  

just for this reason. I think this would be the best solution, but as  

others have noted, some structural engineering support would be  

required. I am not convinced that an access panel in the side of the  

tunnel would make the task that much easier, and as Jason notes,  

still has structural considerations. If I was doing it over again, I  

would consider the belly access panel.

to think about a possible mod while it was still fairly simple to  

implement.  Knowing what I know now, I can promise that if we had  

known about this we would have done something (again not sure what)  

during construction.

Drained and flushed my QB tanks during the build and did not have any appreciable debris. That was even after having to replace an end rib in one of the tanks due to a builder stupidity induced problem. I noted during the first condition inspection that my fuel filter was perfectly clean.

Each tank , IIRC, already has a filter screen. Additionally one can see the fuel flows for various power settings on the EFIS, so some indication of a future problem may be evident. Lastly drain/flush  the main tanks

I’m not sure if it’s possible, but I’ve been thinking of adding one filter at each wing root. 

 

I like the simplified access to the filter, but I also like the idea of having one fuel filter dedicated to each tank.  This way if a filter should get blocked, I can flip to the other tank and access some fuel there.

I was thinking about how difficult it is to service the fuel filter.  First, just to get at it there is a pile of work in removing the tunnel cover.  Some have split the tunnel cover so it isn't necessary to remove the entire cover to inspect the tunnel, great idea, for those still building this should be considered.  Others have installed an access panel in the side of the tunnel in the foot well.  This allows easier access to the fuel filter and fuel pump.  One of the things I really dislike about servicing the fuel filter is that you have to break the fuel lines, and this causes some fuel to spill.  Add insulation to soak up the fuel and you have a recipe for disaster, so you need to use a box of rags to keep the fuel from getting all over the place. 



So here is what I was thinking, I wished that when we built the airplane we would have installed an access panel on the bottom of the airplane that we could have reached up through to get at the fuel filter.  This would have been much easier during construction....  An alternative would be to install a second fuel filter, and place both filters at the tank exits under the wing walk access panel. 



I post this simply to get those who are still building to think about how they will service the fuel filter.  Not sure how we will modify our airplane to simplify the task. 



Thanks, Jason Kreidler

Although I'm not flying yet, can't comment on how  this will work out.   However, I added an acces panel of my own  doing.    See attached link to picasa site.   http://picasaweb.google.com/rcnewman64   click on folder for "fuel pump and access door"    Note,   I'm using the andair fuel pump and have moved the filters/gas colators to the  wing.   I'm not planning on needing to get into the pump area except  for inspections.

Phil, it is possible and I'm doing it. Take a look at this filter for $28.95 from Summit Racing. Very small and filters to 40 microns:
