 |
|
Totally lucked out, was leaving for a quick winter overnighter and my bus stunk like gas. I shut it down immediately, checked underneath and there was a solid puddle with lots of drips coming. Checked the engine bay fuel was leaking from the crimp on the CSV.
Thing worked great before this, and my bus starts in zero-degree weather after only a few cranks.
Is this CSV now junk or is there any way to repair the leak?
I think I know the answer....

i think you’re right in your assumption. we’ll see what the experts say.
just in case, there’s a used csv in the classifieds for $35 shipped, which he says works. check to make sure it’s the right one.

Thanks guys. Its a shame such a stupid failure is a dealbreaker for a hard to find part. Other than the crimp problem, this thing works fine.
I did see the one in the classifieds for $35, but that thing is beat looking. I robbed one off my spare motor, and I know I have another somewhere.

Wasn't there alternative arts from a Volvo or something suggested later in that thread I linked?

Get the hoses off and work a bead of epoxy, the JB weld , non quick set type, into the crimp.
Allow to setup for 24 hours in warm temperature
Reinstall. Run the car for one minute under inspection , then a ten minute ride with cover off , then run for a week of short trips under same conditions.
You will need to inspect that at every fuel stop for six months, then monthly thereafter.
Be honest with yourself. If you won’t adhere to an inspection protocol , then buy a replacement.
I could send you a spare 50 psi fuel pump for testing if you want, pm me

no way. That crimp hold back 40 PSI. Once that JBweld starts to leak the bus goes up in flame. Use the real thing

| You can probably use one from any 1970's car with Bosch L-Jet fuel injection, like a 1970's Volvo, Porsche 914 (with 1.8 lter engine), Saab. Those things aren't usually working unless the ambient air temperature gets close to freezing. If the crimped seam's seal is leaking, JB Weld won't be strong enough to fix it. |

It’s holding a 75 psi fitting in my AWD Volvo tank just fine. Now at 8000 miles

for a guy who makes as much money as you say you do, you could have afforded to fix it right. When it does leak, are you going to take the leaked fuel back to the station and blame them for the leak same as returning used oil and antifreeze for a refund like you say you do? I hope this car doesn't park in a garage where people live adjacent to it.

Well you dodged a bullet! I'm willing to bet there is also a rubber seal in there that's dried out a bit. Mine is feeling so-so - was planning on bypassing it and coming up with some sort of priming system using the main injectors when it finally does.

I just squeak by. I steal photons from the sun , turn them into electrons, and put them into my SmugTank
Broken Volvo fuel pump housing no longer made, had to repair with epoxy

buy a newer car that has parts available and send that one to the crusher where it belongs. And stop being such a cheapskate. Lots of real solutions. I'll bet Don has an answer how to solve it but you pissed him off so much he will probably never share it, leaving you wondering what night the car will start a fire that will burn your home down. At least you will get more heat than the green agenda you support will give you.

I doubt Don thinks too much about how I make him feel, he’s too busy fixing shinola and enjoying the kids. He’s always helped me out with Volvo crap just as I would do go him if I had any knowledge that spanned beyond his
And we apparently are the only two who don’t think panel bonding structural stuff is a good idea. Well , us and engineers.

Let me know what you come up with! I'm stunned no one has figured out a re-pop solution for these. I've seen many of the work arounds, but too much going on. The original is Such a simple piece.
Thanks for the insights Abscate! I scored a spare off my spare engine and will look into another one soon

12 hours in my driveway on my back to put on a PPS?
I’ll PPP ASS on that, thanks.
I could swap in the OE pump into that housing, though, so thanks for that, Don

PPS - Personal Protective Suit? Have things gotten that bad between you and Don? For $112 that is less than the deductible when your Volvo catches fire. It was advertised for a long time as the world's safest car but considering the fuel system can be repaired with JB Weld by a guy who plays with matches ..... well what else is there to say.......
A neat trick to save yourself time when typing is you use that JB Weld to glue some of your fingers to the most commonly used keys - then you can just wiggle those fingers to type the letters...
Mommy, where to ping pong balls come from?
Son, they come from giant weather balloons.
Mommy, do ping pong balls grow up to be giant weather balloons?
Yes son they do.

12 hours?
drop the straps, drop the VC bolt and let it hang and the tank will flex enough to jam a 2x4 between the floor and tank
worse part is dumping the entire contents of the gas tank out, and fucking with the (not so) quick release fuel lines. I actually have 2 screwdrivers bent to do this.
it's a 10 min job on a lift and no gas in the tank. or was before these became rust buckets
lost my ass on the first one, but the rest built my empire
SG- PPS is professional parts sweden... basically volvo's version of empi

I managed to do just the tank by pulling exhaust and the whole VC and squeezing it down, but didn’t have the experience to know I could squeeze the tank down by itself. Thanks.
Those fitting are a bastard, and reworked mine with right angle bayonets so I never have to do that again.
