Poulan riding mower leaking fuel at the carb

Hello,
I have a older Poulan 450-420. Model number is HD14542b. It is leaking fuel right at the carb. It looks like there is a plastic elbow coming out of the carb and the fuel line attaches to this elbow. It is leaking fuel right at this elbow on the carb side. I don't mind tearing the carb apart but my farm is 2 hours away so I need to know if that part is repairable or any tips or tricks before I get there.
Thank you.

Fuel elbow repair

You'll need the engine numbers to get the right parts. You'll need the correct replacement elbow. Than pull off the plastic part & put a little grease into the fitting & tap the hole 10-32 the grease will keep the chips from getting into the carb. take a long 10-32 tap bolt thread a nut onto it place a 1/4" 7/16" deep socket over the fitting thread the bolt into the fitting & use the nut to pull the fitting out. The new fitting is than pressed in.

Thank you. I don't have the puller assembly. Can I make one or is there a work around?

Puller

The puller is just a long 10-32 tap bolt(has threads the whole length of the bolt), a deep 7/16" 1/4" drive socket, 10-32 nut and washer.

I installed an inline fuel shutoff so I don't drain my tank until I get the carb fitting. I think I need to clean the carb as well. Any tricks to that? My craftsman has a bolt on the side to clean it out without tearing it apart. I don't see that on this Poulan.
Is installing the replacment fitting any easier with the carb apart?

Thank you so much for all the help so far.

It would be best to press in the new fitting with the carb off the engine. So you might as well clean it than too. Need the engine numbers Model Type & Code for carb kit numbers. Take pictures of the linkage before you take it apart.
