Diameter of Gas Line ?
« on: March 10, 2010, 12:20:00 PM »

I'm going to run all new fuel line from the tank to the engine.  
I plan on buying the Walbro fuel pump you guys recommended to me.  Can anyone please give me a recommendation as to what diameter gas line should I go with ?
Also, should I just buy a new OEM fuel filter ?

Thanks,
Dave

on the fuel line thing man run the size thats good for you and cheaper on ya because the stock fuel line is like a 1/4 or so line going to a big line is just going to make the return line more in use because your not using all that gas.. if i were you i would run 1/4 5/16 pr 3/8.. others may have another choice... and then fuel filter if your going to replace all the lines i would get and different inline filter because i hate that oem filter being where it is.. yuck lol dependin on room i would put it on the fire wall or something on the way up.. its not something you change alot so...  thats my thoughts

Hey Bryan, thanks - I can always count on you Buddy.

I was thinking 1/4" but I know that using the wrong diameter line can mess up fuel pressure so I figured I'd ask 'cause I know a lot of the guys on this forum have upgraded the fuel pumps.
I would think that 3/8" is too big...so 1/4" or 5/16"  for fuel line ?

Try to stick with 5/16 if you can, I wouldn't do 1/4"

If you've got the bank try stainless braided line - I'll be refitting my Capri with it from the fuel cell forward when I get the time. I have -8AN but thats cause of the fittings on the tank...IIRC thats 1/2" line. The rest of the system I want to run -6AN which is 3/8", unless there is a 5/16" version I'm not sure

Thanks Rocketman.  I'll go with the 5/16" if that's what you recommend.  
Do you think the same for the return line ?
Do you have a preference for an in-line fuel filter?

Thanks again,
Dave
