While I cannot answer on the TR4 in particular, I do have an opinion on
the subject...:-}
>Dear FOT's,

Most of what Triumph did in the brake & fuel dept is somewhat less than
satisfactory in a race environment...
>Q1: What options are recommended as alternatives?
Replace all fittings with aeroquip.
Replace all rubber line with Aeroquip braided stainless.
Replace all steel line with new steel line. (if it's more than a few
years old)
If you are racing and the sanctioning body will allow it, spend the $$
and buy a foam filled fuel cell. Even a plastic non filled cell (drag
racers
use 'em) might be better than a steel one, but I won't go play in
traffic
without a real cell.
The first 3 will cost you about $100. I sleep alot better nowadays, but
I still worry about the fittings on the SU's, esp after Chip's Roasty
Toasty
Adventure.
>Also as a subquestion what do people do about relocating

>recommended?
Race cars should all have fuel pumps in the trunk, near the fuel cell.
Easier to hear them ticking over there when the car isn't running. :-}
Fuel pump manufacturer of choice seems to be Mallory, but I have an
older Facet, which works pretty well. If you are going racing, put in an
inversion cutoff switch.
>Q2: What was the original routing of the gas line for the
>IRS frame vs. the old TR4 ladder frame, and are these considered safe by
>modern standards?
Can't help there.
