It looks to me that the Vans fuel filter in the tunnel will be beyond inconvenient when inspection time comes around. What about two fuel filters, one on each side, in a more convenient location such as under pilot/copilot seat or the wing attach area? Any major reasons NOT to do this?

I can't comment on any reasons to why not to relocate the fuel filter.  It's not my area of expertise.



I can share with you that if you put an access panel on the side of the tunnel, taking the filter out isn't a big deal.  I've taken mine out twice with out removing the top tunnel cover.   Some folks have gone as far as putting an access panel on both sides.



David Ward sells a kit for this and in less than a half hour, you can have it installed.  It's not rocket science, so it's also not that big of deal to fabricate your own parts too.   It only takes me 5-10 minutes to remove the fuel filter.



Another key benefit is being able to inspect the forward part of the tunnel with out having to take everything apart.    This is important for those of us that have center consoles install.

Another way to look at this - the annual inspection requires the tunnel cover be removed anyway.  Once the cover is removed pulling the fuel filter if mounted in the per-plan location is fairly easy.

I found that the tunnel cover itself needs to be shortened to allow more clearance with tubing and such on the forward end.  The cover is shorten enough so that I don't use the most forward screws.  This one thing makes the cover removal/install much easier.

There are more than one way to skin a cat......

The access panels allow me to inspect everything forward of the fuel valve.   I can easily remove the filter and pump through this opening. 

I cut my cover at the fuel valve as to not require removing the forward cover unless something I find dictates it.  

For those of use that have center consoles, this allows us the flexibility of leaving the stack in place during an inspection. 

I then only have to remove the section aft of the cut.

Another consideration is that the stock location is downstream of the shutoff valve.  If the filters are upstream of the shutoff valve you'll have to deal with that also.

Well, what does or doesn't need to be removed for the annual condition 

inspection is dictated by what access panels exist to allow inspection 

of components.

If a side panel access is installed, there is no reason that the tunnel 

cover would ever need to be removed. Since I and a few others have Paul 

Grimstead's Control Approach rudder pedal system, which puts the rudder 

control arms through the tunnel cover, cover removal would involve 

disassembly of a primary control system, something that should be 

avoided for routine inspections. Thus a side panel access cover is 

needed in my particular "modified" RV-10.

  Keep in mind that what does or doesn't need to be inspected is 

governed solely by Part 43 Appendix D, not some one's arbitrary annual 

check list.



As to one filter or two, keep in mind that many type certified aircraft 

do not have any filter between the tanks and the fuel servo inlet, and 

if they do have one, it is often placed downstream of the boost pump, 

rather than upstream as Van's has it. While filters could be put at the 

wing roots, that means twice the work to service, and you would need to 

be careful to locate well clear of the aileron pushrods travel.

Also, any debris like o-rings and such that the valve throws off

will no longer be filtered.  I came to the conclusion that

the filter was positioned in a decent place, and that after checking

it a few times and finding nothing, I was just going to stretch out

my inspection interval of that filter, and make it somewhat also

reliant on what I find in my regular sumpings of the tanks.

The access panel is about all I'd bother doing to improve things.

cover up to the bottom of the instrument panel that will have to be 

removed so the side access panel is a really good mod .... that I'll do.

The Vans filter fits nicely under the seats ...... between the tunnel 

and the fuselage side.  I still might do that instead of the access panel.

Well, your Pitts probably had older operating limits language than what 

is standard today. While a plane today could have different language, my 

understanding of the standard ops limits requires you to use Part 43 

Appendix D as a "minimum" checklist, same as it is for type certified 

aircraft. You can do a more thorough, more detailed checklist, but not 

less than Appendix D. One of the few sections of Part 43 that applies to 

amateur built aircraft.

Thanks Kelly. It's taken me 35 years to get back to building ...... I 

have a lot of catching up to do!!!
