| Subject: | IO-240 Fuel pump |
I have a 1997 IO-240 and the fuel pump started leaking fuel again. 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?
Thanks,
Tim

Hello Tim, I am sorry to hear that you are having a fuel leak problem
with the fuel pump on your IO-240 XXX engine. 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.

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.

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.

Hello OC,
Thank you for your response, I have the same fuel pump that you had. 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.
Tim
