Fuel Accumulator removal 82 911 SC

[jasonlee]

Just wondering if there isa trick to this. Been having a hot start issue, so ordered a new accumulator. I now its not the check valve, because I have a brand new fuel pump. All that said, just checking if there is a trick to getting this out of the car. Any insight would be appreciated.

Thanks

You know it's not the check valve because it's a brand new fuel pump?

What pump is it? The check valve is a separate attachment on some.

The accumulator removal should be straight forward. It's held in by a hose clamp and the attachments to the fuel line and filter. Use a flared wrench if possible to prevent damage to the fuel line nuts.

When putting it in, you must loosen the filter a bit so that the hard line between the filter and accumulator can sit on both fittings square before you tighten them up.

Ensure that you have a check valve before putting that expensive part on that you may not need.

Good advice^^.

Your 82 accumulator can be checked to see if it is faulty as well. Remove the hose from the bottom of the accumulator and plug it (a little fuel will flow from the accumulator, that is normal.) With the hose plugged and a container or another hose connected to the bottom of the accumulator ending in a container, start the fuel pump. If fuel flows from the bottom of the accumulator, it is bad and needs replacement. If no fuel comes from the accumulator, your hot start problem is from some other source.

seems easy enough to replace, can't get my flare nut wrench on the bottom, but further its really tight, is that normal? Should I try a little penetrating lube to help with the loosening?

Use 2 stubby wrenches, one on the nut of line and one on the nut on accumulator placed so that they oppose each other like a "V" and pull them together.

Just did mine recently (filter & accumulator) and 2 wrenches + penetrating oil did the trick. Also, found this advice in previously linked 101 tech article helpful "If necessary, disconnect the line from the top of the filter, and the bottom of the accumulator, and remove the two as an assembly. This will allow you to take the two over to your workbench to disconnect the hard metal line that joins them together."

And - likely goes without saying though none of this stuff ever does for me - keep in mind proper direction for loosening top and bottom.

Please post if this solved your hot start problem.

I will keep you posted. I have to get the old one out first. I suspect this is the culprit

Follow the above suggestion using either open or flare wrenches. Do not forget there is clamp holding the fuel accumulator on the bracket.

Yep the V method with the 2 flare nut wrenches squeezed together is what worked for me.

I had what I thought were accumulator problems. I was told by a Tech guy to use non-ethanol gas. It seems to have done the trick. The alcohol was causing vapor lock in hotter weather. Cost more but well worth it

[jasonlee]

No Ethanol gas would be great. When my car was in Vancouver, Chevron had 94 octane with no ethanol. However, here in So Cal i can't seem to find a non ethanol alternative.. All that said, the accumulator is old, so it certainly cannot hurt to replace it.

It is premium and 360 a gallon, but worth it . The car runs great
