Sounds like your fuel pump. There could also be a fuel filter but usually you
find that under the bonnet (hood) near the carb. Do you have the Zenith
Stromberg Carb? Anyway, it could be an after market fuel pump as well. Also,
the SU fuel pump for a 78 should be in the boot (trunk) just left of the right
rear wheel well. When youturn the ignition on without starting the car, there
should be a clicking sound while the pump fills the line and carbs.

Subject: fuel leak near right rear wheel...
Hello,
I went out to the grocery store this evening and filled up my '78 MGB
on the way. I recently did a basic tune-up and cleaned and tweaked the
carb, so I was curious to see what mileage I was getting.
It turned out I was getting 10 miles per gallon - about half what I got
before the tune-up! I thought and thought and figured there must be a
leak somewhere, the car is running nicely and that difference in
mileage couldn't be explained by something being out of adjustment.
Sure enough, when I got home, I looked and saw a drip coming from the
line about a foot or so forward of where the fuel line comes out of the
tank (on its way to the carb).
It's nighttime and I didn't have a good flashlight so I couldn't really
see very well, but there's some device there that - for a moment -
looked like a big in-line fuel filter. I'm sure it's not, but I don't
know what it is. I'll certainly investigate in the light of day
tomorrow, but does anyone have any ideas? It appears that the fuel is
leaking from this thing or from a connection to this thing. I couldn't
find anything like it in any catalog or reference book I have.
Auxiliary fuel pump? Giant fuel filter? ??
Thanks!
