Fuel Starvation issue

My rover runs and idles pretty well, its strong on accelerations, and runs well under heavy throttle.. Well at least for a little while. Under extended periods of heavy throttle, it starts to cut in and out. Most often this happens on hills, when cutting in and out is not only annoying, but dangerous.

My thought is that the fuel in my carbs float bowl runs out, and my pump isn't working hard enough to replace what is being used. I have a weber 34 ICH carb, and a brand new mechanical fuel pump.

The fuel filter never fills up, not even half way, not even a quarter of the way. It always has just a few drips of gas in it. It's very unsettling to me.

Is there a way to up the fuel pump's pressure? Or do I need to just make the swap to electric.

Thanks all,
Kyle

Possibly a daft question.....have you got the right jets in your carb for the altitude?

Also (given your location) what about carb icing.

The jets in the weber carbs are set up for volks beetles apparently, as andyb66 says; are the jets correct?. i found this a problem here in NZ. I got a tiny wee drill set for drilling out carby jets...Good as now, but oxy acetaline nozzle cleaners should do an ok job?

I'm pretty sure my jets are fine. This has never been an issue before. I've had the beast for almost two years now. The car seems to run fine, I drove it 20 miles yesterday with no problems. Then parked it for an hour and when I returned to start it, couldn't find the power to get it out of my driveway, it just kept stalling out.

Weird...

have you checked you fuel lines up to your pump?, if thats all clear, i suspect your pump, even if it is new it could still be dodgey. just use your noggin and it'll soon come clear whats wrong.

So. It's been almost a year and I finally got this issue fixed. I swapped to an electric fuel pump. I installed the Facet 1-4 psi pump. It's a bit noisy but I'm going to use some rubber to isolate it from the frame and reduce the noise. Just thought I would update this in case anyone else had the same problem as I did.

This new fuel pump also eliminated an annoying vapor lock problem I had on hot days. It was a very good buy. About 60 bucks for the pump, bolts, and hose. I made a block off plate with sheetmetal for the old pump. I had the whole thing installed and running in about an hour.
