hey Gimmie Green i just relized your low pressure pump is before the filter. you should have a filter before the pump to keep crap from the tank out of it. other then that NICE 
It is finally time to start my tuned port conversion

Hey Lone Gunman,
The high pressure fuel system definately took a lot of thought and soul searching. Ininially I wanted to use a fuel tank out of an EFI equipped 94 Blazer. I did some research and found that an in tank fuel pump for a 91 TPI equiped Camaro would fit right in to the Blazer sending unit assy. The guy at Napa also told me that a lot of the EFI cars shared that same pump, including certin years of the Blazer as well. So I purchased the pump for around a hundred bucks ( far less than any 50 psi inline pump that i could find). Unfortunately I just was not satisfied with the fit of the Blazer tank. I put a lot of time and effort into making it fit, but in the end, after thinking about my future plans of a four link rear and lengthened wheel base, I decided to cut my losses and scrap the idea. After another IH8MUD consoltation It was clear that a surge tank was the only plausable option. I didn't want to waste my money so I decided to try and make my Camaro submergible pump work. My first idea for a surge tank was to use a spent fire extinguisher, but after two days of unsucessful search a piece of 1/4'' wall square tube and some 10 guage cold roll caught my eye. First i cut the square tube down to 7" then i cut a piece of 10 guage for the bottom and welded it solid. Next, I cut two pieces of 10 guage at 6x6. One of them I cut the center out of so it matched the inside dimentions of my square tube. I then welded it solid and drilled eight coresponding holes in that plate and the other piece of 6x6 10 guage, thus creating a flange. In the top plate I drilled three holes the first two were for the pressure and return lines and the third was for the wiring harness I robbed of of the Blazer sender. I cut the AN 6 steel fuel lines off of the blazer sender used a tubing bender to bend them at 90 degrees. Then I brazed them into the lid. the return protrudes through to about a half inch from the bottom and the pressure only aboun 3" from the top of the lid. I then used a heavy duty hose clamp to secure the Camaro pump to the return line sticking through the bottom of the lid. the gates submergible 3/8" high pressure fuel line to connect the pressure outlet on the pump to the steel high pressure line was kinda hard to find. Once i recieved it from a company that had it online i secured it with a pair of fuel inj clamps. I used a piece of tractor intertube cut to size for a gasket on the flange for the surge tank. I drilled two holes in the square tube for the inlet and return lines from my lift pump. I welded two nuts over the holes and screwed two 3/8" hose barbs wraped with teflon tape for gasoline into the nuts and my surge tank was complete. Oh yeah I used stainless braided fuel lines out of a 91 TBI chevy p/u to connect my surge tank to the fuel rail.
By the way thanks for the FYI in the low pressure filter placement. I dont know what I was thinking.
sounds good! to bad the blazer tank didnt work out. i thought about doing something simular but all the sites i could find basicaly recomended the surge tank so i went that route.
take care! and i will look for your posts on the seat install if you do them.
