Fuel Line Problem on Alumacraft Tourn. Sport 175

5 posts in this topic

Submitting this for a friend in Missouri who runs a 2005 Alumacraft Tournament Sport 175 with a 140 Suzuki. He is experiencing major problems with the fuel flow/fuel line. The motor starts great and runs great when it runs. He will be going along just fine and the motor will cutout and quit. A few pumps on the bulb and he is back in business. This cycle may repeat itself 3-6 times on a 20 mile run. When adding fuel, it is like he can not get any fuel in the tank without it almost overflowing immediately. Obviously that is not due to a full tank. He has had it to the dealer at least 4 times, they monkey with the vents, fuel lines, etc. and tell him he is good to go. Not so. He has now contacted the dealer and made arrangements for Alumacraft to pick the boat up and get the problem fixed. I thought I would put a feeler out on FM to see if anyone has experienced a similar problem or could offer some ideas or suggestions. He has had this rig to Canada 5 times now and had problems everytime out. Other boats in our group have had no problems so don't think it is a fuel quality issue back at camp. On behalf of my buddy, thanks for any help.

If he experiences overflowing when filling up tank he has a bend on overflow hose, gas sits there then when he fills up air tries to escape from hose blowing through and looks like it's overflowing.

Gas tank might get into vacuum since there's no venting and pump cannot pickup gas. If this is the case Alumacraft has to pickup the tab since they have to pull floor and fix vent hose (brobably cut too long). Try to tell him to run with open gas cap, this way tank can vent through filler hose.

Thank you for the reply. As usual, Valv, you provide great information in easy to understand terms. I do want to ask one question. Is it safe to run with an open gas cap? I am not by any means a mechanical genius but that sounds like it could be a bit risky to me. Just want to follow up on that suggestion. I did forward you first response to my friend in Columbia, MO. Thanks again.

Is it good to run that way for a long time? No, probably not. But, it would be fine if, once he was on plane, to open the gas can and see if the problem gets better...

Then you'll have an idea where to start.

If you (or your friend ) are smokers definitely the risk is a little high, just take precautions and be careful. It is just a suggestion to test the theory, it's tough to diagnose something without being actually there. You could get boat on plane then open cap, and if possible try not to have a full tank, just in case, you don't want to spill gas in the water

      Del, We only got about 1/2 inch of snow but more snow and rain is predicted for Sunday and maybe Monday. Only 22 degrees for a high here yesterday! 39 degrees now and supposed to get to 50 degrees today. Crazy spring! Probably still frost in the ground in most areas. Cliff

      Hello Everyone, May is just a few days away and I'd love to see how the water is warming this Spring through Summer... Can we start a thread with daily water temps? Date: East side or West side: Location: Temp:   I'll be there June 10th! Thanks, ~Tripp in ATL

      Not a fishing report, but a question....   Is the frost out of the ground yet?   Bringing some stuff up to the cabin and wondering about water lines and stuff freezing and all that.   I see the forecast is for the 50's next week..     How much snow did you all get?

        I keep and eat fish also.  I was just reacting with a snide remark to a tone of "I want some fish to eat, got any spots" that perhaps was unintended .   If so, I apologize.    Many of the streams in SE Minnesota are populated primarily with native brown trout, and the DNR information is reasonably reliable.  There was a major kill in summer 2015 on the very popular south branch Whitewater river and I don't know how the recovery is coming along.    Cause still unknown.      Some recent info....(not about kill)   http://www.postbulletin.com/sports/outdoors/giving-nature-and-anglers-a-hand/article_dfe73b76-5cd9-520c-834f-7d4101a40b2e.html   http://www.postbulletin.com/sports/outdoors/john-weiss-trout-cooperate-for-a-fantastic-opener/article_2b106b9b-595f-5bee-8c3b-ceb761179da1.html   The DNR stocking activity is accessible from Lakefinder.   Here is the info for rainbow trout for 2016, the latest year available.  It will give you an idea of the activities.     http://www.dnr.state.mn.us/lakefind/showstocking.html?year=2016&county=&species=RBT
