Hello,
I have a 1962 M38A1 CDN2 95% restored. I am having a problem with gas getting into the oil pan. The jeep ran great, then it sat for almost a year and I was having trouble getting it started. I found that it was flooding horribly and gas was getting in the pan. checked the carb and the diaphrams were cracked, I have rebuilt the carb and the jeep starts and runs good, however there is still gas getting into the oil.
I am thinking something with the fuel pump might be causing this. If anyone has any suggestions or thoughts it would be greatly appreciated.

thanks,
ron

More than likely you have a hole in your pump diaphram. I have never experienced this problem with a jeep but have had it happen to me with GM built cars. They can put a lot of fuel down in your oil pan in a short period of time although your engine is still running fine. Time for a rebuilt of the pump or a replacement

Im with Gamillerman on this. I just rebuilt my pump. Take the pump off and on the flange where it bolts to the engine you will find a 3 digit stamped number. Call up Then-Now Automotive http://www.then-now.com/index.htm
They can link the number to the pump kit you need to rebuild your pump. Cost me $47 US for the rebuild kit both ends. You can also send them your pump and they will rebuild it for you. My M38 fuel pump has been great ever since.

Thnaks for your help, I will pull the pump off and get the number off and order the rebuild kit.
Gmillerman, I read in a earlier post you found out the primer lever has to be put in a certain position, did you find out what the correct position is?

Thanks again for your help.
Ron.
