I'm still fighting my fuel starvation !!!error: Indecipherable SUB-paragraph formatting!!! , still without any luck. In one last valiant attempt I decided to tear down the timing gear cover, in hopes of that the fuel pump eccentric might have gone bad... Sadly (?) it hadn't. This was the last thing that could possibly be wrong, everything else has been checked and double checked. Dammit I have no idea what to do now!, seriously considering calling it quits for the season and simply start building on another engine for next year...

Fuel starvation? Could be a chunk of crap in the fuel tank that intermittently covers the fuel line. I seem to recall you've replaced all the rubber fuel lines? Have you done a reverse air blow to make sure it's not a pinhole in either the rubber or metal lines that's allowing the fuel pump to pull in air? A buddy just had that issue on his old MG. Also, new gas cap to make sure you're actually able to pull air into the tank as fuel is drawn out?

Sadly it's not. I've even tried running it with just a 5 liter gas can that I placed in the engine bay, with the same results. I've pinned it down to the pump (which is new) so that leaves me with what? A new pump? Again? Idk seems highly unlikely that I bought a faulty new fuel pump.

What about float adjustment? Is the float too low?

Hehe nope. That was one of the first things I tried, which was like 2 weeks ago :P I've got a quick release on the fuel line to the carb from the pump. When it dies from getting up to temp, I can release it and physically see that there's no fuel leaving the pump as the ignition is turned.

So, the pump isn't moving fuel, essentially? It is possible that your new one is faulty. Possibly the check valve is stuck closed, or nearly closed. Crud maybe got into it past the filter. I'm putting an electric fuel pump in my car to help avoid this sort of thing.

Idk man, I just don't know any more... This problem started while I still had the old pump, and it persisted with the new one. Very unlikely that they both failed, but who knows?
And yes! My next fuel pump is also going to have to be an electric one now. This is a type of problem I never wanna spend neither time or money on again!

Could there be a piece of debris lodged in the fuel line before the pump? A piece of rust could easily get part way down the fuel line before getting jammed in there.

How is the pump driven? If it's with a cam and a little pushrod could it be either of those that are worn? I don't think you get replacements for them with a new pump.

It's driven by that round thing that sits before the timing gear (the eccentric drive, as it's apparently called). From what I could tell it looks good and the pump arm has been making good contact with it also. It's a 2 piece part with an outer ring that spins freely around the inner. I think it can be bought separately for not too much money.

Sorry nothing that simple. As I replied earlier; I've had it hooked up to a separate gas tank, with different lines and everything and it's still the same.
