Fuel Accumulator - replacing the cloth feed hose

[82DMC12]

I'm working through a hot start and low primary pressure problem and it appears my accumulator is on the way out. I replaced it once but it was perhaps 15 years ago. At that time I replaced the rear flexible hose but I did not replace the front one that comes from the pump. It still has the cloth sheath on it. What's the best way to replace this while I'm in there? Is it best to just cut the line off of the fitting point downward and attach a new high pressure fuel hose to it with fuel line clamps? I seem to recall you can access some of these fittings from above if you remove the center console. Is that recommended to really get this done right?

The reason I think the accumulator is bad is because when I remove the rear soft line from the single port, and then jump the RPM relay, there is a steady drip coming out of it at a rate of perhaps 2 drips per second. My understanding is it should not leak at all.

Here is the information from when I did the job:

Thanks! I had already been in there once so it wasn't too hard to get everything apart again. Not sure why I didn't replace the high pressure hose back then but I'll take care of it now. No worries cutting the line off of the fitting.

Cool. Good luck. Make sure you torque the fuel injection clamps properly.

Thats right the single hose pointing forward should never have gas coming out, if so, the accumulator is bad

What do you recommend? My first instinct is to use the smooth fuel injection band clamps and tighten them until the "feel tight" but not so much that it strips. Then test for leaks by jumping the RPM relay. Advice is appreciated.

For both sizes, it looks like the maximum torque spec is 13 in lbs. (Inch pounds), but I would verify with the manufacturer of the clamps you buy. I always torque to spec on any fastener and I never have problems.
