After figuring out the logs and fittings needed for me to setup a third 04 pump, I think I am just going to replace one of my 044 pumps with the 4303. The parts will run me close to the cost of the new 4303 and it will take up less room. I have a lot of fittings but not that many. lol..

As stated, make sure you feed that 4303 well. They don't like to be starved.

It will be a -10 line. Cell only has a -8 bung on it. Bigger line wont help it, the -8 bung is the restriction.

Can you drill the tank sump and install a -12? When I sent my 4303 back to Magnafuel to be freshened they said it showed severe cavitation signs. I was feeding it with their -8 fitting.

That way you could leave at least 1 044 on there the way you have it and drill the bottom of the sump for the 4303 feed.

Believe it took me about 30 minutes to install a -12 bulkhead fitting w/ Teflon washer in the bottom of the fuel sump on a poly cell.

Good idea. Ill add a -12 to the bottom of the sump and leave the 2 -8s in it.

I had used some black expanding foam to seal in the cell. Looks horrible but works well. Even have a 90 which I'm sure isn't ideal but seems to get the job done.
