Moon tank question

Hey guys did a search and couldn't find an answer. Anyway, I'm using a moon style tank on my '27 and it's mounted in the rear just about even with the roll pan. So it's pretty low. The thing I am wondering is if anyone has run hard fuel line, but then used rubber hose for the last 10" or so to get into the bottom port of the tank.
I'm wondering how it holds up considering the port is at the bottom and if gravity will blow the hose off where it meets up to the hard line.
Is that ok? I will be using a small amount of rubber hose up front to the fuel pump so I thought it may be the same idea?
Thanks

 

post some pics-this is an actual gas tank with fuel gauge sender? -likely best to use AN fittings and electric fuel pump-Summit Racing has what they call Twist-***e Hose, but do not know if for gas.

 

I wouldn't use 10' of rubber line period no matter what kind of a tank I had. Braided steel is good if you need to run a flexable line, but your absolute best bet would be to hard line it all the way back use a highflow elbo if you need to get it to go 90 degrees in a short space.

I doubt that gravity will blow the line off that's what hose clamps and either hose barbs or a flair on the end of the line is for.

Just my thoughts on the matter.

 

Ya it's a moon fuel tank. I can hard line it all the way, just will be a pain in the ***. Up front it's cool right? I am using a manual pump at the motor and need a little flex there.

 

I've used rubber fuel lines for years without any problems. My '65 Biscayne came with a hard line but the ends were rubber.

 

That's why I thought it would be ok. My Cadillac has rubber lines at the front and rear going into the tank. That was from the factory. Hard would be better. I'll just have to put the body on and then finish the lines. Too much guessing right now.

 

Nothing wrong with using rubber or the modern equivelent of it at the ends of the line. I just woulldn't use 10' of rubber line. There is a difference in an isolation joint and a long flex line.

 

There is no good reason to use rubber, unless there is a likelyhood of flex between the fuel line and the thing you are connecting to. So at the fuel tank, no good reason at all. Use hard lines, as suggested earlier. At the motor, you need flexibility, but don't scrimp. Spring for the good stuff.

That's the price you have to pay to be cool.

 

I'd like to see a picture of your installation. Traditionally, Moon tanks are mounted high enough to be self priming to the fuel pump. If your tank is mounted that low is the dicharge fitting in danger of contacting road obstacles. If there is even a remote chance of that happening you had better rethink the mounting location.
