If its not already posted in this thread...the ability to read fuel pressure to the rail is fairly simple but very important...you need a couple of 1/4 t-fittings 10-20 feet of 1/4 inch fuel line and a pressure gauge that reads 0-100psi...contact me if its not easily found...many of my posts tell how to do it...if your fuel pressure is good or bad takes you down many different paths to a fix but good fuel pressure rules out many things

OK. Now it is sounding like you have a problem with level of fuel in the VST bowl. Either you might have an obstruction in front of the float needle valve (restricting amount of fuel coming in to fill bowl), or the float setting is too low (?), or your low pressure fuel pump(s) are damaged (age-diaphragm leaking, trash-frm bad fuel, bad check-valves - cracked/broken)? If you have not inspected the internals of fuel pump(s), that might be a good place to start.

It has been a while since we looked at the entire thread here, but you may have to go through some of these same procedures again?

Good luck, will wait to hear back from you.

Well I think I found the problem. There was a leak on top of the VST tank, the hose that runs from the LP pump was leaking bad. I did pull and rebuilt both pumps and they did not look that bad inside.

Yes, that leak could surely cause your problems. At higher rpms when fuel flow is maxing out, your motor could be pulling air if suction is greater than the pump pressures.

Good luck, post back when able on how the repairs work out.

Yeap that was it. Went out for a ride today and she did great, no more surging and she runs like a top now, again thanks so much for you help Solarman.

That's why we're here, just trying to help.
Am glad you worked it out.
Happy boating.
