spectra gas tank modifications

[jorgezee1]

I have an old style spectra gas tank. out of warranty. this does not have the new baffle installed on it and it has starvation issues at about 1/4 tank. Can I modify the tank? weld a new baffle in? not me personaly but a shop. I am still running the stock pump does anyone have the walbro part number to upgrade this pump? I have searched and I did find some part numbers but it seems a few people have run different part numbers on these. can anyone confirm the pump they used?

Thanks,
Jorge
