Smalltownbird Posted June 19, 2020 Share Posted June 19, 2020 I am having my grandfathers star chief straight 8 sedan towed to my house so I can try and get it running and driving again. It hasn't been driven in 14 years, although 6 years ago I put a new 6 volt battery in it and got the engine to turn over but it never fired. I wanted to get the tools and supplied I need together before it gets to me so I can be prepared. Does anyone know what size fuel line I can get to run from the pump to a gerry can to bypass the old fuel in the tank just to get it running? Thank you!

Bloo Posted June 19, 2020 Share Posted June 19, 2020 5/16" I believe. You will probably also need a 5/16" hose barb with 1/8" pipe threads for the pump. The original setup most likely uses a crimped hose and some 'threaded sleeve" fittings. The fuel pump itself should have pipe threads after you remove the brass fitting. Consider rebuilding the fuel pump or having it rebuilt. The old pump diaphragm will probably not stand modern gas for more than a few minutes. 2 Link to comment Share on other sites More sharing options...
Smalltownbird Posted June 19, 2020 Author Share Posted June 19, 2020 Thank you! Do you think a new old stock fuel pump would work or do the internals need to be rebuilt with different materials? Link to comment Share on other sites More sharing options...
The 55er Posted June 19, 2020 Share Posted June 19, 2020 You will need a rebuilt fuel pump with modern internal materials if you plan to drive the car. 1 Link to comment Share on other sites More sharing options...
Smalltownbird Posted June 19, 2020 Author Share Posted June 19, 2020 Ok, that's a shame. My grandfather kept a lot of extra parts in the trunkni was hoping to get away with using. Ive been looking for parts to prepare myself but it is hard finding things for an old pontiac Link to comment Share on other sites More sharing options...
Bloo Posted June 19, 2020 Share Posted June 19, 2020 Try Kurt Kelsey (KornKurt here on the forum) and California Pontiac Restoration respectively for NOS and reproduction parts. Then n Now automotive has fuel pump rebuild kits and also a rebuilding service, with modern materials. 1 Link to comment Share on other sites More sharing options...

Bloo Posted June 20, 2020 Share Posted June 20, 2020 (edited) It was a 5/16 flexible line wasn't it? My 36 had that setup originally, might again now that I have all the parts. The threaded sleeve fittings needed to hook a long line or hose to that stock crimped hose are not readily available in most areas. Thats why I suggested he take all that stuff off and temporarily install a hose barb. A 5/16 hose barb with 1/8" pipe threads ought to be in any NAPA store. That and a long hose should get him set up to start it on the jerry can. Edited June 20, 2020 by Bloo (see edit history) Link to comment Share on other sites More sharing options...
Smalltownbird Posted June 22, 2020 Author Share Posted June 22, 2020 There is actually a barb coming out of the bottom of the pump with a soft line already on it so I think I should be able to use that. Thank you!! 1 Link to comment Share on other sites More sharing options...
