I'm at a loss as to how to connect steel brake line (3/8") to nylon fuel lines. Is there a fitting made for this?

 

Do you mean straight line or the GM quick connect style?

What I'm trying to do is go from 3/8" brake line to GM nylon line. All I can find are -AN fittings and I don't have an AN flaring tool just regular SAE.

 

Something like this work? Put nut on steel line, flare it & use this fitting....?

Best method is to flare the steel line for a GM quick connect. You need something like this set from Mastercool 71475. I bought mine a few years ago on eBay when someone had is mislabeled for a smoking deal.

 

Dorman makes a fitting to do it. Its a compression fitting on one side, a barbed fitting for nylon hose on the other side. I've used them and never had any problems with them. Its Dorman part number 800-035. Just Google it and it should come up

 

That's it! thanks Nova. Can't understand why this didn't show up on my searches.

 

curious, would this work for fuel delivery for EFI (LS type- 58psi) fuel pressure?
sorry if it is a silly question... just thinking....

thanks

 

I used it on my truck that I swapped a 5.3 into, and it just rolled over 61,000 miles, so I'd say yes, it works.

 

I've personally never had good luck with compression fittings. I'd just find a buddy who has a Mastercool set that you can borrow, or have come over and use. It takes about 30 seconds to flare.

 

LS1, thanks for the replies I figure if it is good enough for you & works then it has got to be a reliable and working solution. ryeguy, I hear you... that tends to be my luck on comp fittings as well... sometime I get them to "Seal" and other times they just don't want to work for me...
