Replacing fuel pump
« on: January 06, 2010, 08:51:06 pm »
Anybody have any suggestions on removing the fuel output line from the pump? The pump was installed when the engine was out and the shop must have over tightened the nut. I'm using a line wrench but the it won't budge. I'd hate to have the cut the line and have another one bent. It's not stock and it would be tough to re-bend a line and have it fit.

Any help would be greatly appreciated!

Definitely use flare nut wrenches. PB blaster is your friend. Tighten the fittings if you can first then try to loosen them. Holding the wrenches in a position that allows them to be close to each other allows you to just squeeze hard to crack em loose. So position the wrenches strategically.

Thanks to the set I just bought from you, Vile, I have a flare nut wrench. I'm not sure what you mean by positoning the wrenches... It's just one nut. And excuse my ignorance but what's PB blaster?

like as if you were squeezing closed a pair of vice grips. The right wrench is higher than the left wrench but in close proximity to each other. Now SQUEEZE

I gave it all I had but it appears to be twisting on the nut... or starting to skin the nut.

i was also going to suggest wacking the wrench with a hammer---this could help break it loose.

But if you are using a flare nut wrench and it's beginning the round off the nut, i'm not sure what to do next besides cutting the line, which means you'll have to get a new line i think they're like $20 pre made.

Couldn't he just cut the flare nut off and re-flare the end of the line and add a new nut?  The line would only get shorter by 1/2" or so?  First post says its not stock, so I assume he means the fuel line is custom bent and a replacement would also have to be custom bent???
