[Healeys] fuel problem

[Oudesluys]

These are not impeller pumps but diaphragm pumps. As they both tick away
I suspect that they are just full of dirt from the tank.
Dismantle, clean, check and rebuild and fit filters between tank and pumps.

"burnning" out on 2 occations. I didn't see a final resolution if there was
one. I have had 2 electric fuel pumps in parallel on my BT7 for years. One
went about 3 months ago. I just thought it was old age. Since then the car has
become fuel starved on 2 occasions. It sills run for a short distance and then
dies, full choke sometimes keeps it sputtering along for a while. Both pumps
are working (they click very fast) but no fuel delivery to the carbs when it
begins to die (scant fuel and a occasional bubble in the filter). On each of 3
occasions one of the pumps eventually died while the other kept going but
still no fuel (shut it off so I didn't have to replace 2 pumps). The dead pump
wouldn't work at first on the bench but after shooting some lubricant into it
it began to run-seemed like the impeller had become stuck. After being towed
home the car started right up the next
>  morning on the still good pump. . I've never had a problem with vapor lock
in 15 years and think that an electric pump should overcome it anyway but all
three times it was a hot day. I think the pumps are not getting gas which I
suspect lubricates the impeller then it binds and the pump stops. Gas tank
seems ok, no leaks. no junk and the filter before the carbs is clean. Any
ideas.
