Title: 70 challenger 383 - non emissions - which fuel pump?
Post by: mtterry on November 08, 2022, 04:40:16 PM
Which fuel pump should I have my 70 challenger? I see them with barbs only, then some with thread and barbs.

Also there are varying lines/kits... Not sure which is correct.

Anyone have any pictures of how it routes behind the alternator etc ?

Thanks in advance!

Bellow is a link to the fuel pump.  Do you have the Holley carb?

None of this car was together really when we purchased 10 years ago. It's got a Holley double pumper on it now.

The fuel line kit I got had a compression fitting on it... Does it route back up just as a tube? I'll have to convert back to a thread for the fuel line off the carb.

Excuse any incorrect terms... Just an IT guy playing 3 -6 weekends a year... Need to step it up lol. Kids, house, work... You know the deal. (https://uploads.tapatalk-cdn.com/20221109/ef4af80bc515dbda68256e012ef30d11.jpg)

I run the lines up from the pump and filter between the alternator and the water pump housing. You can make your own to adapt to the holley or buy pre bent lines to get it close. https://www.inlinetube.com/products/sdee7008

This is the factory routing for a Holly non emissions car.

Yea that's the lines I bought, but my fuel pump has two barbs and not the compression.
