fuel pump

I installed the walbro 255 fp last weekend and I have a few questions. I noticed that when taking the oem unit out of the assembly, it was sitting in it pretty firmly and I had to pull on it pretty hard to get it to come off the assembly, but when I put the walbro unit in the assembly, it's not sitting there as firm as the stock unit was. I can pull on the walbro unit and it comes off pretty easily. Is it supposed to be like that? The walbro unit also sits on the assembly loosely, without the bottom bracket and screw on, is it supposed to be like that? The oem unit was actually sitting nice and firm in place even when the bracket and screw was off of the oem unit.

Also, the hard fuel line on top, I pretty much bent the crap out of it, not that bad, but Im pretty sure it's bad enough to cause a restriction, is there anyway for me to just replace that hard line? I would hate to have to cut it and use some high pressure fuel line in place, although that isnt a bad idea because I cant get the ####ing white cap to screw back on the fuel tank.

Thanks.

Looks like you fubar'd the fp assembly. That's why it's suggested to disconnect the line from under the car. Anyway, I would use some reinforced fuel line (not your standard fuel line) to replace the kinky with some worm clamps. DO NOT use tin snips to cut the line because you'll end up smooshing it anyway. Make sure you use something like a dremel to make the cut so that you keep the fuel line round.

Why the reinforced fuel lines instead of the standard ones?

I've been busy and totally forgot about this thread, but please refer back to my previous post, and yes, I've got the full fuel mods.

Tie wrap the pump to the assembly, that will hold it. As for the line you can replace it if there is enough of the hard line left to seal a new line.
