I think my 1572 is jealous of the new 1772

Also, you may try pulling the line feeding the pump and see if fuel comes out. Just to be sure..... It's a quick test, and you should only need to do it once.

Oh..... was the pump from CC? Or some kind of aftermarket? How old was it. Hadn't been on your shelf for years or something had it? They are just a rubber diaphragm pump. They can go bad sitting.

Jonathan, the pump was an actual CC pump, new in the box but was on the shelf about 2 years. Still had the rubber caps on the input and output.

This still has me puzzled as how this could be running perfectly fine for over an hour with the new pump, starts acting up, I check the pump output and it appears to be dry, then once pumping runs for another hour and finishes the job.

Frank, what happens if you pull the inlet to the pump off and hold it below the tank? I'm thinking the screen or something else in the tank is causing your problem.

I agree with Todd. Check the flow from the tank. I've seen fuel filters from the larger diesels, 1466, etc., plumb full of junk or algae. The gas/fuel today just isn't what it used to be.

Todd and Josh, I think that is an excellent next step. Unfortunately during the week, it's usually dark by the time I get home from work. I plan on looking at this more on Saturday. I want to disconnect the fuel line below the tank and see if fuel runs out at an acceptable rate. That will tell me what the next step is. If I get a good rate, then it may be another bad fuel pump. I really hate working on the 1572 trying to get to the fuel shut-off, having both the 3-pt hitch and read PTO. The fuel shut-off is buried behind all the covers and shields.

I'd plan on pulling the tank, cleaning it out, replacing the grommet for the fuel shut off and cleaning or replacing the shutoff valve. My bet is your going to find something in the tank that is blocking the flow.

[FrankF3]

Sam, you're probably right. Fortunately I have some grommets and valves on hand from when I did the same thing to my 782D while replacing the old dried out fuel lines. It may be the time to replace the fuel lines on the 1572 as well.

I did what I mentioned on my 1782 shortly after I bought it. I was surprised at how much crap was in the tank. The Cyclops have 2 fuel shutoff's and one was packed full of dirt the other just barely flowed any fuel. You having only 1 shut off may be even more challenged.

I'd tee in a vacuum gauge to the inlet of the lift pump. That will tell you if you have a restriction or it is just sucking air (leak before the pump). The pump is cooled by the fuel, that is why it is getting hot.

Thanks to all, I finally had time this past weekend to look at the 1572. I ended up pulling the 3PT cover off , then disconnecting the fuel line at the shut off. As I took the line off, I had more fuel dribbling out of the free end of the hose than I got out of the shut off valve. It was barely even allowing anything out. I pulled the tank, washed it out, then rather than clean the screen on the shutoff valve, I just put a now one in. I ran it as before and no dying or surging with the motor for lack of fuel. Thank you everyone!!!

Glad you got it back and running. I had to change both filters on my 1782 today. It would run ok but then just shut off. Did that a couple times, decided it was time for new filters. Local Bota dealer had them in stock along with the O-Rings for the secondary filter. So far all good but I need to run it under load to be sure all is good. I'll let you guys know if it has a problem.
