came out from behind the hangar, where he had been constructing toy Thrusters out of sticks and grass, steppped on an echidna, and slid across the strip. "Woo Hoo!" said Hy Undai. "Aww, he's not here is he?" asked Ssan Yong plaintively. "At least he tells a better story thanLatty's leitelative cockpit dlibble" said Great, who had been set right by...

If the hose liner is playing up, the normal bending and inserting of an engine change can trigger it. It would be nice if the solution is this simple... (thinks out loud) can you grab a second electric pump, or borrow one from something with a larger flow requirement, and plug that on in lieu of the engine? If such a super-sucker delivers an adequate flow rate into a bucket, then there's nothing wrong twith the airframe fuel system, and it could only be the engine pump. (thinks again) how much time have you wasted on this already? V. frustrating!

Tell 'em only Lib voters fly... they don't deserve the truth...

I'd put 2 bob on it being s fuel line liner problem, because I can't imagine any other possibility to match the symptoms

I've had the little rubber seal on a float valve needle disintegrate, causing blockage and yuk, but that was on an ooooold carby... and I'd think you'd notice the rich behaviour if the float sunk?

... even through Sydney traffic? Sure...

Write your MP - Australia needs a "Paid build your own aeroplane leave scheme"...

tsk, tsk... this from a man who used to ride a 6-cylinder Honda motorbike...

Brick walls are not good for flight! Ummm - it couldn't be vapour lock, could it? If you mix fuels, and as they age, you can get vapour lock surprisingly easily...

Worth asking - but unless I missed something, a collapsing inner would still fit the bill?

If the filter is between the pumps, definitely try that first.

Yes, the idea is that the valves on either pump will allow fuel to pass through even if that pump ain't active. Fuel hose is normally made with an outer, a robust string-reinforced body, and a liner. I have had happen to me twice (once car, once U/L); and heard of several times; the liner comes loose from the body. Now, if the liner between the engine pump suction and the elec pump outlet did this, with elec not running the suction partly closes the fuel line; and the elec pump pressurises it back to full size. To test this, get a length of line - the cheap clear not-really-fuel-resistant stuff is ideal - and run it through the cab, or on the ground outside, from the elec pump outlet to the engine pump inlet. Then ground run the engine. If it works fine under test, you've got yourself a good spare engine pump! - and the pleasant job of replacing the std fuel hose with something of at least equal quality... (as far as I know, NO lined fuel line is immune from this problem, ocassionally)

I've seen a guy hand-carving spar extrusions with a router, so a piddling little template iught to be so easy...

Speaking generally - I don't have a Jabiru - the engine should have been shown to develop full power with either pump out of action; so is there a fuel wasp's nest in the line, or a collapsing inner or something?

Jealousy's a curse, Oscar!

whinge b****y whinge - you're definitely management material...

Ta. I shouldn't have given the book back, obviously...

Look, the future of the nation is worth a high price... how about a replica P-51 with a drag-racing V-8 to provide the excitement of EFTO?

Agree - I hotwired a few model aeroplane wings on a 1-m frame, using an old electric blanket transformer (OLDE!), ply templates... I also suggest do not get impatient and saw with the wire, it does cut but because the ends are cooler than the middle you get an hourglass effect - small but irritating. I'm using al because I want high reproducibility, and it's easy to shape very accurately, and the wire slips along it like a dream.

...how the smell am I going to take off without runway lights?" Meantimes, the plick in tight shorts...

According to the Encyclopaedia of Commercial Aircraft, the AN-14 was developed to replace Aeroflot's AN-2 fleet - so they must have had one? (fleet that is...) My T-83, with the 503 de-tuned to ~40hp because of the crap points ignition system and single carb, gets 3.1 gallons/hour (per seat, also) at 45kts, so the AN-2 is cheaper on fuel... perhaps a little more costly on engine overhaul?

No worries... I'm working up another serve, as the family allows :o)

...arrack into her rose, and after that she didn't remember much... "HAY!" yelled Simon Datsun-Dunlop, "what's that plick in tight shorts doing to the Gulfstleam???". All eyes turned towards the patch of darkness he was pointing to, before Ssan Yong said "you really past it, Gulfstleam THERE", pointing at the taxying Gulfstream...

...was grinning at the sight of ratso and Great writhing in the dust...

...and then fell through the side of the tent, did a commando roll, and jumped to his feet - right in front of Maggot, who...
