It did this once before and I had it rebuilt. The engine only has 518 HRS TT. Is there a problem with the pump? Do the newer engines have the same pump? Any suggestions?

You wrote: 1) =9CIs there a problem with the pump?=9D The simple answer to that question is: Yes. The complete answer can get complicated. 2) =9CDo the newer engines have the same pump?=9D The simple answer to that question is: Probably the same basic IO240 BXB pump, but with some different subscript numbers attached to the basic pump P/N 653351. But again the answer can get complicated. 3) =9CAny suggestions?=9D Yes. First download and review in some detail these two publications so that you have a fairly firm grasp of exactly what fuel injection assembly you have on your engine (probably a P/N 649059XX-X) and which pump you are dealing with (probably a P/N 653351-XXX) and some past history on modifications and changes to these fuel injection assemblies and pumps. http://www.tcmlink.com/pdf2/CSB01-1.pdf http://www.tcmlink.com/pdf2/SIL98-6B.pdf Then, with these details readily at hand, give CM technical support people a call at 888-826-5465 and get their advice on what to do next. Please let us know how you make out. Thanks. OC 'O C' Baker says "The best investment you can make is the effort to gather and understand information." PS: For example: My IO-240 B9B engine, serial number 806236, manufactured on 9/1/1999 came with fuel pump P/N 653351-2. On 7/3/2001 I complied with TCM CSB 01-1 to remove that pump and install pump P/N 653351-2A3. ===================== From: Tim Yoder Sent: Sunday, October 06, 2013 3:03 PM Subject: KIS-List: IO-240 Fuel pump I have a 1997 IO-240 and the fuel pump started leaking fuel again.

Also, my engine S/N 806822 mfg. 4/18/97. Interesting that it is a higher S/N than yours that was made almost 2 1/2 years later. I will read the info you sent but what is the difference in the -2A3 pump. It was a close call yesterday, I was able to divert to a field about 7 miles away and just made it with the rpm continuing to fall off. The electric boost pump kept it running.
