Susan, if you have fuel starvation only in the proximity of the corners, it
is almost always due to one of two things -- either the fuel cell pickup
location or the carburetor float bowl orientation, and almost never by the
pump, filter, or regulator location.
You can check the fuel cell possibility by running your car with a
completely full fuel cell and then running it on a nearly empty cell to see
how it acts.
What kind of carbs are on your car? If you have Strombergs, let me know and
I'll go through the litany of things we tried with Strombergs on The TR4
that never solved the problem.
If you have SU's, look at the float bowls and note the location of the
pivot for the float. If the pivots of both are on the outside or inside,
you will have this problem due to the fuel sloshing up the side of the
chamber and making the floats either close the float valves or open the
float valves, depending on location of the valves now and the direction of
the corner.
The fix for this is to oreint the float bowl tops so that one pivot is
towards the rear and one is towards the front. Do this by just rotating the
float chamber tops. Sometimes it is awkward because it leaves the fuel
inlet pointed the wrong way for a tidy routing of the fuel line. There are
also fixes for that, since there is a big variety of float bowl tops with
various inlet and vent patterns.
