Happy 4th to all! Please fly the FLAG!

Guys,

I am replacing the fuel line and am going back with stainless. I am also installing the Howell Fuel Injection System with electronic ignition in a stock engine. Given this, What are the preferred fuel line sizes?

I would like to come out of the tanks with stainless as well.

I Can't tell you guys thanks enough, but again, thank you all,
Tom K.

P.S. I am leaning to Ken H.'s suggestion of a duel fuel pump set up.

I am curious what are the advantages of stainless fuel line?

I've found stainless beastly to work with - hard to bend, hard to
flare and generally a PITA.

Have you considered using Copper / Nickel line? Easy to work with and
somewhat less expensive than stainless.

Stu,

Harder to work with, but once done they are forever. I am restoring A 1977, 23' Birchaven and want to tour the country. I am hoping if I take my time, build it right I will have few problems and more piece of mind. All the tanks are out and the frame is open from one end to the other, so now is the time.

Take care,
Tom

Here is the tool to put the bead on the lines, if you want the original style bead.

Tom,

More than a few years back, I had fuel system troubles. Much was related to failing rubber lines. I redid all the fuel lines that I could with Polyarmor. This was much easier to work that stainless would have been. I happen to know this for a fact because at one time in my widely varied (and somewhat lackluster) working life, I was an instrument fitter in a shipyard (where else?).

Stainless lines can be flared, but the mechanical limits are such that 70° is about all you can do. This is a very different tool than you are used to seeing. This tubing can also be coupled with special compression fittings. These came from either Swagelok or Parker, but there may be other suppliers now.

As you approach this, look up and read "Recommending High T". This is a mod that you really want to do while you are in there.

Matt - do I have to add BTDT?

Matt,

I was going to use double annealed Stainless steel lines and I am awaiting a 45 Degree flaring tool built for stainless lines.

If I am not successful I will defftnetly look at the other options.

Matt, What does BTDT mean ?

Thank you to everyone for your responses.

Take care,
Tom

Matt,

I just read about the vent lines. Thanks so much for the heads up and I will definitely incorporate the vent mod in the rebuild!

Thanks again,
Tom K.
