Questions: My 62 CJ5, 4-134 F head, currently has this fuel pump installed. The previous owner(s) plugged off the two vacuum ports. The jeep has electric wipers. I'm wanting to replace the fuel pump and was curious if the single action pump could be used now?
Question By: Lyle Brown on Sep 29 2018 2:29 PM
Yes, a single action can be used. 119238 - but you may have to rotate the diaphragm a bit for clearance.

Questions: My wipers (at least the driver's side)is now electric. I have a 57 CJ5 so the old pump had no wiper lines, what do I do with the lines on this dual action pump?
Question By: Mitch Hatch on Aug 2 2017 11:56 PM
You would need to port them together with a hose so its a loop.

Questions: On this fuel pump do both vacuum line out ports provide vacuum and does it matter which side is used for either vacuum line? Thanks in advance - Rick Installation diagram available ?
Question By: Rick Hoffman on Jun 15 2017 1:16 PM
The vacuum is the larger side. Yes on the vacuum - it is a suck/blow. So don't plug them off or the pump wont work properly. You can either connect them properly to the vehicle, leave them open (not recommended due to dirt getting in there. Or run a hose between two.

Questions: This should work but I have a 58 FC 150 with the 4-134, this will fit correct? Curious due to the proximity of the fuel pump to the motor mount on an FC 150 along with the amount of connectors that tie into the fuel pump.
Question By: Flo Kinzel on Sep 30 2016 1:20 PM
Yes, this pump will work for your FC-150.

Questions: I have a 1957 willys cj5, it has a dual action fuel pump with a glass bowl. I can't seem to find one like it anywhere...will the 120206 fuel pump work? I do need the vacuum for the PCV system, but am not going to need the vacuum for the wipers...what do I do with the port for the vacuum hose for the wipers if this pump will work?
Question By: Lana on Aug 25 2016 11:57 PM
120206 would be the proper pump for you and your original lines would hook up properly to it for your CJ-5.

Questions: Hi, Will this fit a 1961 M38A1
Question By: chris on Aug 25 2016 9:14 AM
Yes, but you may have to rotate the diaphragm for front engine mount plate clearance and re-run your lines. It is correct though for the 4-134 engine.
