Fuel line access

[Robert Hicks]

Greetings, does anyone have any tips or tricks on getting the fuel line off the back side of the firewall that go to the electric pump? I cannot get a wrench or crows foot way back in the to get it off. 63 C model.

Take the engine side hoses loose and maybe you can turn the bulkhead fitting and hold the flare nut on the hose.  Get a set or 2 of inexpensive harbor freight i.e. china's finest wrenches and heat, bend, grind and cut to fit.

 

that hose does look a little crusty

That way you don't feel bad grinding, cutting or bending snap on tools.

Try a smaller crows foot wrench, you should be able to get in there.

Thank you both for the replies. My crows foot won’t fit so tomorrow I will try to bend a cheap wrench. And yea I think taking off the fuel lines on the engine side may help. This hose has to be older than me...

This might work....... It might be cheaper to cut up a cheap box end wrench and weld a ratchet extension to it. 

Interesting (to me anyway), my ‘63C (sn 2552) has a hardline between the boost pump outlet and the bulkhead T-fitting.

What year and model Mooney? As I recall you are correct  a crow  foot  protrudes too much. I took a sacrificial socket grounded it down enough to fit over the fuel tubing  and had friend wield  sacrificial socket extension to the sacrificial socket. But it seems to me I had remove the fuel  line  at the firewall once  before I made a special sacrificial socket tool. Next time I am down at the airplane I take a picture.

It’s a 63 C model.

A flair nut crows foot wrench won’t work, you need a straight version to remove the hose.

My crows feet are too big to fit in the little pocket. I followed the advice above and removed the inside lines and was able to get the old one off. I will have to bend a wrench to get it back on I think. Thanks all for the advice so far.

I think it safe to say that this won't earn me any Charles Taylor award but I think it worked.

not the prettiest tool.

Charles Taylor was an awesome fellow...

As brilliant as the two other yahoos he worked with.... 

+1 on getting a good look at the fuel hose showing cracks on the exterior...

One of the odd places junk comes from, that sticks in fuel injectors, is the fuel lines leading up to them...

Of the multi layered fuel hoses... the exterior is pretty far from the interior, but the age is what seams to cause both to fail slowly...
 

Consider the carb to be like two fuel injectors... it has two jets similar to FIs in their sensitivity to being blocked...

PP thoughts for consideration only, not a rubber hose expert... or carb expert...
