I am having fuel delivery problems with my 383. I have a 110gph Holley pump and new filter. I just replaced all of the rubber lines. I blew the hard lines out when I changed the rubber. I still am only able to get 4 psi of fuel pressure at the carb. I have tried three different pumps. I have a feeling my "sock" is plugged. Can I just remove it? Or do I need to buy a new one? Thanks everyone.

I removed mine several years ago after haveing simular problems...As long as you run some sort of good fuel filter you shouldnt have any problems...

69LS1 is right on the money. I'm still running the stock tank and 3/8" pickup. I removed the sock. I have a Fram canister style filter just ahead of the electric pump in the rear and a Russel -8an inline filter towards the front before the carburetor. No problems whatsoever.

I made my own pickup with 3/8" tubing and no sock. It works fine. Just change your fuel filter regularly. 25,000 miles with three fuel filter changes and no troubles.

Awesome guys, thanks for the help. I always run a filter before the fuel pump so I think I ought to be good there. I may get a Russell, I guess, just to make sure there aren't any problems. What filter would you guys recommend that won't cost me and arm and a leg? (Say less than $30, I am sure the $100 filters are great, but I can't afford that for one car. ;) )

It's not advisable to run the fuel filter before a mechanical fuel pump. The filter should be between the pump and the carb. I think it's OK to put the filter before an electric pump (maybe even necessary).

Restrictions in the line before a mechanical pump can cause problems. The "sock" was only designed to block large particles. Since you have the fuel pickup removed from your tank, I'm assuming you've cleaned the inside of the tank if it's old.

cjlandry?????

Holley advises a non-restrictive filter between the pump and the tank.

Electric Fuel Pump Installation Tip:
Mount the electric pump (motor side up) close to the fuel tank but below the fuel level so as to realize a good gravity feed to the pump inlet. Use of a good non-restrictive screen-type filter between the tank and pump will protect the pump from dirt and contaminants from the tank and will also avoid a fuel restriction or pressure drop at this point. NOTE: Pro-Series VOLUMAX pumps are equipped with a 45 micron fuel inlet screen.
If you don't have a VOLUMAX pump, run a NEW sock.

Read it again. I said not to put a filter before a mechanical pump. I also said that it's OK and maybe necessary to run a filter before an electric pump. I knew I remembered reading somewhere that it's good to filter before an electric pump.

Oh, my bad.

Shoulda read closer. graemlins/clonk.gif
