mechanical fuel pump - 73 cj5

Probably only the satisfaction of having fixed it yourself if you pay someone ~$150 in labor to replace a $15 part. I dunno, though... I've replaced fuel pumps before, but never on a Jeep. I'd be really surprised if it takes more than 20 minutes if you're taking your time from the experiences I've had with other vehicles. Do you have a shop manual? If not then this is a good reason to buy one and read up on the procedure. If it does only take 20 minutes or so then I'd brave the cold and do it myself.

This is a very simple job.

If you are losing oil through the pump, there is a chance that you also are getting fuel in your oil. I would change the oil and filter as well. The "book" probably says to charge 2 hrs to do the job ... that plus parts puts you in the 150-175 neighborhood.

If you do it yourself, inspect the fuel lines while your in there and be sure to scrape the block clean of the old gasket before installing the new one.

If you don't experience problems, you should be able to change the oil and filter and replace the fuel in under an hour. To help with the cold, start the motor and let it warm up a bit before starting the repairs.

That or have the shop do it and stay warm inside.

Good luck.

Two bolts and a hose fitting!

It seems a little steep to me too.

It is a simple job... no way would I pay that much.

A half hour labor is highway robbery for that pump job, let alone 2 hours.....

That really sounds like a pinched elbow in the PCV line to me or a broken oil pressure sender though. The PCV tube has a molded elbow in it, it can collapse under high vacuum situations when it gets old.

Did any oil get in the air filter?

The gas pump gasket will just leak oil, the fan can blow it around, but it will be localized. Not a pressure fitting there and kinda obvious.

Oil pressure sender at the top bolt can do that, it is under pressure, so can a blown valve cover gasket because the fan blows that, which is also PCV related. Mike

Matt,

I have seen people take thier vehicles to an indoor parking lot to work on. There is no dignity in it, but a 150 bucks can buy a lot of dignity or enough beer to restore your dignity.

Oh ya, we started the job in full snow suits and finished in short sleeves. The weather really changes fast around here.

It is anther beautiful sunny day today though.

here's the update.

after 'probably' being chastised into getting off my lazy arse, i sucked up the 20 degree weather this morning.

actually, the oil pressure sending line is leaking ever so slightly. the freeway miles must have increased the flow and the fan just blew it everywhere.

and the vehicle is running rough because the fuel line is leaking...right on the manifold. that's safe. geez.

thanks for the responses...and the heckling.

safe holidaze,

I think I would wrap the fuel pump in aluminum foil and then see whether the inside or the outside of the foil gets the oil.
