Airflow Performance fuel pump mounting

[blaplante]

I'm going fuel injection and will be using an airflow performance fuel pump. So... the price isn't too bad... but some how once you add in all the mounting/installation kit the price from Van's gets north of $600. What's all this then? Is the kit worth it or is this just stuff I can fab myself? Anyone have any tips/pointers/advice?

Of course you can fab it all yourself. But if you don't want to do that, getting the parts really helps. Do yourself a favor either way and ask for the plans sheet for the RV-7/7A showing the cockpit fuel system. It's different from the -6/6A, including the fuel selector mount, and so you may want to make extensive changes in front of the spar. There's been a thread or two on here about this, so a forum search is also in order.

Extra fuel tubing

I think is uses about 3 feet around the pump and filter. I'm certain it took me about 12 to get it right.

Can't speak for the effectiveness of the parts yet, not flying, but I know that building an RV-6A 'now' has changed, more of us are adapting the RV-7x FWF, and cockpit layouts. This was a bit more complex for me, because the 'plans' are somewhere between the -7 and -6, with some ingenuity required. As a result, I appreciated the 'kit' approach to the filter, pump, and tubing components. After all, I'm eventually expecting to achieve 'airplane' status and a little help is good.

If you change to the -7 fuel selector, tunnel cover, and tubing mods, you'll have enough to challenge you, without fabbing all the tuning in the AFP installation.

Yes, I am doing the -7 tunnel cover, -7 battery box, and -7 style fuel selector box in my -6.

Plan for mx

Just something to keep in mind. I reworked the entire fuel system a couple of years ago to make it more maintenance friendly. I can now easily remove the whole fuel pump/filter/valve assembly from the plane if necessary. I recommend designing that in, even if it means a couple more fittings and connections (and their corresponding potential for leaks and failures).

Good luck!

It all depends ?

I put the pump and filter on the .o63 plate with the rubber strips and supplied worm drive hose clamps. That was not too difficult, but I bought the whole deal plate and all.

To make your own plate you will need at least a square foot of .o63 of 2024-t3 Aluminum and then cut, and then form fit, and de-burr.

You will need a brake capable or making the correct radius.

I bought the kit to make faster progress. (14+ years)

Best wishes!
