Gtting closer. I found grease around the inside of one wheel, so a rear repack/reseal is tomorrow's project. Interesting seal happening. AutoZone had two, Timken seals. Ordered me two more, they showed up as Duralast, the house brand. Same opart numnber, same number stamped on the metal holder. The Timken has a layer of wht looks like red sealer painted on the outer rim, the Duralast has not. They were made in the same factory though... at ;east the parts were.

Measure them according to the tutorial here. http://www.gmcmhphotos.com/photos/rear-axle-seals-skf21771/p36356-says-made-in-the-usa.html

Can use 1/4" copper tubing to test:

I found out why the electric pump I had didn't help vapor lock. I had plumbed it between the aux tank and the selector valve and powered it off the valve. In order to progress to a pair of electric pumps, I simply got a second one and bolted it on the steel plate beside the original, Teed the outputs toward the front, and put in a relay to power each pump the way the tank switch is set. In prep for mechanical [pump removal and blockoff, I pulled the rubber hose and aimed it into a pan for a test. Key on, select main, lotsa gas out into the pan. Switch to aux, not nuthin'. Wandered back under with a meter, 12V on the selected pump, no [problem. But, no action out of the aux pump, problem. Damn. Removed it and noted, the label was a bit discolored, like from heat. Applied it directly to the battery, draws current, gets hot, no noise. So, a bit of destructive testing is in order. I cut the swaged portion of one end off, lifted it out, and lifted the end plate off the pump. It's a vane pump, vanes were free but the rotor was seized. Lifted the rotor and vanes and then the bottom of the pump chamber off, armature still seized. When I pull the armature out, a piece of the negative brush was jammed in amongst the winding slot on the armature, jamming it to the magnet. I'll get a replacement tomorrow and bolt it all back up and we should be good to go as far as fuel delivery is concerned.

I'm sending the manufacturer a complaint. It will be interesting to see if they stand behind their product. I suspect the answer will be since I opened it, no go. However, if I look at the time and trouble to send the thing back so they can cut it open and see the same thing it ain't worth the hassle. Time will tell.

Found the invoice, pump was over a year, warranty was 90 days. Chit.
Anyway, made them aware of the problem, and o0f the sorry - ass input filters they supply, which are designed for failure. Meantimes, I was gonna put the replacement in, but Duke - 10y/o BWD suddenly has a serious problem, so the day will be spent at the vets.

I have had lots of pumps go bad, in my VW's. Knocking on wood the one in my coach still works. I use it as aux, and my primary is still mechanical. but I do use it to prime everytime when I start the coach, so I can hear it, and know it is working at least at that point.

I had luck with a carter 4070 pump on my grand wagoneer as a primary pump for 3-4 years. but it is a more expensive, bigger pump then the mr. gasket type I have on my coach, and what i have tried on my vw's.

I have had 1 mr. gasket, 1 faucet, and 2 airtex pumps go out on my buggy in the past 3-4 years. but my buggy gets alot of abuse. Some lasted a year, others did not last a week, and 1 airtex pump worked intermittently. That one was a bugger trying to figure out what was going wrong. I finally quit with the electric pumps on the buggy got a good german mechanical pump on my buggy, and so far so good.

I actually had a new chinese mechanical pump not able to keep the float bowl filled at full speed at first, and then went to electrical after messing with the rod lengthes and spacers trying unsuccessfully to figure that pump out.

I'm replacing with the same on the theories of
1. I don't have to fab a new mount, it fits what I already made, and
2. I don't think they will both fail at once.. which means I can make it to Advance for another.

I was unable to find a correct pump blockoff plate on short notice, but the Mr Gasket 1517 (I think, ended in 17 anyhow) with a hole drilled in it works just fine. I expect very few people will see it. Anyhow, I screwed the hardline into a hose barb after removing it from the pump, and the flex hose slips on without bending it or other modification. Now, should I become disenchanted witch the dual electric setup, I've an unused mechanical pump in the box. The selector valve remains with caps on all three fittings. Therefore, about 30 minutes plus time to mount the mechanical pump and she's back to box stock if I want. When the injection system goes on, I'll file the quadrajet in another box along with the two lower pressure pumps and simply hang the two 18 - 20 PSI pumps on the same mount. Flexibility be us. I took the compressor bracket off to get the mechanical pump off the engine, is it possible to get the dam' thing on or off without disassembling a bunch of stuff? The old pump had a lot of slop in its action compared to the new one I have. This may of contributed to my vapor lock problems. Finding out the first electric one wasn't working has boosted my confidence that the coach will blast over Monteagle. Given the somewhat higher line pressure from the back, and with a look at the OKC toll booth Crispy Critter, I have a firefight foam system for the engine bay on the way from Bounds' emporium. I'm beginning to feel like the bartender whose cat pissed on the cash register - 'this is running into money...' However, if all the upgrades over three years keep doing as well as they have, I've only the genset to address mechanically... and it's used so infrequently that I'll probably just limp along with it till I need one for a long weekend and do the Ken H Thang at that point. I can live without a self-commencer on the genset, somebody will have a $300 sale on 5KW units eventually.
