Primer pump upgrade

Who has done it? How difficult was it? Where did you get it and what did you pay? I'm searching in the meantime.

Cost $18 and some change from eBay and was a simple screw-off, screw-on and prime job.

You can buy one from here for $12-15. I replaced mine with the Bosch that looks like a shotgun shell yesterday. I still have gremlins in my fuel system though.

Because of access problems, it's not nearly as simple in practice as it is in theory. A crow's foot and long extension bar will be a great help. Removing the fuel supply line fitting will give better access, also.

I used a vice grips to get the old one off, and a short adjustable wrench to put the new one on. As for cost, I got it for like $12.

Thanks guys, just what I wanted to hear. I soaked the engine compartment with "shout" for two days and went and pressure washed everything. I think the primer pump was the source of the mess I had while on a trip. I think the leaking diesel fuel got blown everywhere and loosened up all the oil under the hood.
While the car is running the pump will leak a drip on the ground within a minute. Probably more while running down the road.

Thanks again.

Usually that will ruin the engine mount on that side too....

Both of my engine mounts are brand new. The old one on that side was totally separated.

For installation the Crows Foot is safer.
The Basin Wrench is a type of pipe wrench. The harder you turn the harder it grips which makes it good for removal. However, a Basin Wrench could warp/crush a new Primer if you are not careful when you tighten it making a Crows Foot a better choice for installation.
