having fuel starvation issues on the freeway.
cruising at about 65 mph is fine but if i try and hold 75 mph for more than 2-3 seconds the car will start jumping slighty and hesistating, pushing down for more gas... more hesitation.

thinking a fuel issue, so I replaced the fuel filter, no change...
so figured my fuel pump is giving out.
Bought a walbro and as I was doing the install I noticed something odd.
When I relieved the pressure at the hood banjo fitting I noticed some sputtering of the fuel instead of a nice even release. I removed the bolt completey, so all pressure relieved.

Then when I went to the tank and released the banjo fitting there was more pressure releasing on the other end of the fuel line! WTF? the fuel line is just a straight hollow tube right?

Ignored it for now, and confident the walbro would solve all my problems, I finished the install and started it up. Took it for a drive and the hesitation is the same if not worse!

I do suspect the injectors, they have alot of miles on them (200+), and I'm planning on some new ones next week.
But... something is telling me that won't fix it, because there is something really messed up in my fuel line.

whats the best way to flush the line, or should i replace it?

 

When you opened up the fitting at the fuel tank did you have the fuel cap off? There is pressure inside the tank and its recommended you take the fuel cap off

 

I did take the gas cap off, i just forgot to mention it.

What I saw was... line pressure after the tank pressure was relieved and the banjo at the hood was relieved (taken off).
It spewed a little gas like there was built up pressure in the old pump. But i figured that would have been relieved already under the hood. maybe I dont understand the whole fuel line yet.

 

sounds like a clog in your fuel line then. get a new fuel line from somewhere and call it a day.
