pulse pump issues

[lunnex]

Hi, Ive got'a 94 16hp vanguard that has been stalling out at high rpm and when on an incline, but otherwise run great. I have replaced all the fuel lines, filter and cleaned the carb and tank. still no fix. so I decided to check th pulse pump witch was replace last year, i found that it seems to be working find at idle, but as the rpm rises the outputing fuel becomes a sputter. So I nest checked the pulse line from the head and it seems ok.
Any thoughts or do I just go for a new pump?
Also, I had to add an inline bulb primer during the summer because it would
emply the fuel bowl and stall before self priming itself.

This is a fairly common issue in the ARGO machines with the Briggs. With the tank being under the seat, on an incline the pump just can't lift the fuel well enough to keep up with demand. Argo sells an electric pump, but you can get the same one at NAPA for a lot less $$. the part # is BK 610-1052 for the pump. just wire it into a circuit that turns off with the key so you can't accidentally leave it on. here is an old thread about the subject: http://www.6x6world.com/forums/engin...tting-out.html

I was reading about the electric pumps but i also seem to have a problem with it. there are only two circuits coming out of the fuse block, tow are open with no power to them. so I've got main lights, tail lighs, heater fan and aux 12v jack on one, and fog lights and bilge pump and winch of the other. so occasionally it blows fuses, and I have accually melted a fuse in their once. so I would be concerned about adding another draw on the system.
How are the accesories normally wired in?

Another issue with pulse pumps is the use of gas with ethanol in it, breaks down the rubber parts in the pumps quicker.

I'll try taking the pump apart and see what going on. stupid ethanol.
