Part# 05-03637

Overview

The kit is replaces the worn O-rings (2) on the primer pump used on non-fuel injected engine installations. The primer seals frequently are not re-lubricated until someone complains the primer isn't working or the engine is hard starting. This is most evident by the pump being hard or stiff to operate. Generally speaking, by the time the pump stops performing, the seals are worn (to the point that lube is of little value) and must be replaced.

Reviews

1965 C 172 F. My primer was dry, rough, and wouldnât hold prime for start ups. 10 minute installation with this kit, and my primer worked like new again.

This kit was exactly what I needed. For a couple of months, the primer in my C150 seemed to be doing less and less and eventually, it just stopped. The kit was simple enough, just two O-rings that restored the seal and now it works like it was supposed to work. The directions that came with the O-rings were perfect. Thanks

Worked very well. Use a small pan (ie dish pan) underneath just in case it drips fuel when you remove the plunger.

I used this kit to restore my primer. Took all of 10 minutes. An easy fix for an annoying problem. Primer is now as good as new.

Q&A

Q: What are the dimensions of the o-rings in this Primer Overhaul Kit? I have a Lukenheimer primer on a Cessna 140.

The dims are as follows: 3/8" I.D. x 1/2" O.D. x 1/16" cross width of o-ring.

Q: FYI: I just measured the O-rings on an Essex primer. They are the same dimension as the O-rings in this kit.

Ok thank you for the information. We will post it for other customers.
