Fuel Lines

[zukirider21]

Hey I'm doing a carbed 302 swap and Im going to try and use the stock in-tank fuel pump with a quick fuel return-type fuel pressure regulator (summit # QFT-30-899). Can I just get brass hose barbs, heat them up a bit, and push them in to the stock fuel hoses (the type with the super hard plastic tube on the inside and the rubber hose around that). or am i going to need to run AN line or something aftermarket?

the correct "high-pressure" barbed fittings would work above 300 psi without clamps. which part of existing fuel lines do you plan on tapping into?

FWIW, they make a female end spring lock that has 3/8" NPT thread that might screw right into your regulator (I used one w/ a Holley regulator). I used spring-loks so that I wouldn't have to cut the stock lines, but they are a pain to locate.

well unfortunately, i already cut off the old spring locks so i guess im going to try and get something like this: http://www.summitracing.com/parts/SUM-G3116/ thats probably not the right size but you get the idea. on second thought, after looking closer at the description of that regulator, is it the right kind? whats the idle jet supposed to do?

you can buy those at autozone, but that is not what is considered a high-pressure barb.
where did you cut the line? depending on what year your truck is there is hard-lines somewhere, i would cut, flare and install fittings that will give you a 3/8" barb and you can go to autozone and buy some of their high-pressure "fuel-injection" fuel line (at 3 freaking dollars a foot) and run that to your regulator, if you wanted to you could then run a low-pressure hose after the regulator

ok so what exactly is a "high pressure barb"? and does what, 40psi? warrant the use of such equipment? what if i ran a new rubber hose from the outlet of the fuel filter to my regulator, then adapted the old return line to a "low pressure barb" (my original plan) on the regulator, and of course ran new rubber line from the regulator to the carb. that should work right?

yeah that sounds like that would work
hard to explain the subtle difference, but they can be discerned by the little yellow plastic collar at the top of the barbs,(if you look at them sidexside the barbs are shaped different) and i guess that 40psi could likely go either way. i just always run high pressure stuff on e.f.i.

alright now that you mentioned the plastic collar i know exactly what youre talking about. just like the hose in this kit, right? http://cgi.ebay.com/ebaymotors/351-...ptZMotorsQ5fCarQ5fTruckQ5fPartsQ5fAccessories

any idea where to find them?

Just do it safefly--whatever you do...fuel can shoot 20 ft. with no problem.......one of the fuel hoses is gonna become a flamethrower is it ever gets loose!!!!!!!!!!!!

I coughed up $30 & used the high pressure 300# fuel hose.....way over kill on the pressure.....but the hose is super-tough...& where-ever it rubs againts sometning...I'm gonna put a larger piece of rubber hose over the hi-pressure hose & tie-wrap the outter hose in place....

just in case I live another 60-70 years!!!!!!!!!!!!!!!!!!!!!!!!!!!
