Hi Aslan,

I'm also a 240 guy. I thought you used to have one too, also an 89? Probably I am dreaming.

My gauge is the first thing I pull out when working on one of our three k-jet 240's for fuel trouble. I know how much my accumulator holds when I try to contain the fuel that wants to escape when connecting the gauge. The first amount, under pressure, seems to be a hundred, maybe 150 ml, then the remaining is gravity from the filter high up on the firewall.

But when the gauge is connected, the filter and accumulator are filled by the pump and line pressure established in about a count of three (three seconds?), so I am thinking your extended cranking sounds more like the result of flooding than lack of rest pressure. Leaky injector? I know you said they were renewed recently. I would pull plugs after an hour or so, to check for fuel.

Like Phil, I'm surprised to hear there is no check valve at the pump outlet. I know single pump systems, where the pump is inside the tank, don't need one, but I'd think if the pump is remote from the tank, it would be prone to vapor lock without one.
