Actually is a lot easier once you have the correct length of line is to install from inside the tank. You either install the filter on the line first or wait you know you the correct amount in the tank and fish it out and then put the filter on.
Norm I replace a lot these type of lines here. Enough in fact that I buy the lines in 50 foot rolls. I do however prefer the Nitrile rubber line over the Tygon F4040 plasticize lines and it whenever I can. Some customers and techs alike spend a lot of time trying the push in the lines. I just relined two Weedeater string trimmers that the fly by night tech spent over an hour trying to get them in and I did it in less 5 minutes including getting the tools and line out of the shop. His jaw hit the floor.
He said it was the $15 he spent learning the trick.
