Fuel tank help

[Chrysis]

Let me preface this with I'm miserly and really prefer cheap to easy.

Before I decided to drink the LSx coolaid I purchased a new fuel tank. One of the blazer style that fit under the bed. I also have a fuel pump assembly from a 2005 Silverado. I'm trying to think of the easiest, and more importantly cheapest way to marry the two?

I've considered Modding the tank to mount the Fuel pump assembly but I find it hard to cut into a brand new tank. I've also considered fabbing a surge tank and putting the Silverado fuel pump in that. I have an inline pump and filter that I can keep the surge tank filled with.

Any other ideas?

Wow, its ironic that I just came in from the garage after doing this very thing! I just cut into a brand new blazer tank to mount a 2002 truck pump and sender. I did it because there's no good way to baffle the tank and with high pressure efi, baffling is important to keep from starving the pump when fuel level is low. With the new silverado sender/fuel pump/bucket thing you don't need the baffle since the fuel bucket keeps fuel at the pump. Its definitley not the easiest way, but works the best in my opinion.

Did you just cut the hole in the tank, or did you recess the area to get the fuel line connectors flush with the top of the tank? I ask because the stock sender is recessed, so I was concerned there may be a clearance issue.

I recessed it about an inch. I have pics on my phone that I can post in the morning. Not finished welding it yet though. Mine is going in a Blazer so I have a crossmember going across the top, so I had to.

there is a company (which i cannot remember currently) which makes a weld-in o-ring bung for GM pump units. I came across it when I was figuring out my swap. Kinda wish I had gone that route instead of the spectra tank.

I saw one by Vaporworx P/N RWTAK, but 259 bucks. Is that the one you were thinking of, I cannot seem to find any others.

Vetteworks http://www.vetteworksonline.net/cata...products_id=89 makes just the weld on ring and it's only around $60, but you HAVE to have room at the top of the tank, don't think it will work on a 67-72 truck without recessing it.

Here's what I'm doing to mine, not finished yet, but I've done it in the past with good results.

Excellent! 60 bones is more in the area of where I want to be. =)

LS1Nova71, I take it yours was removed from an existing GM tank? The one I can find at vetteworks
http://www.vetteworksonline.net/cata...products_id=89 doesn't appear to use the GM mount ring. What they have for sell was almost exactly what I had in mind to fabricate though, so it's good to see my thinking was right.
