year one fuel pump to carb lines
 

i just recently installed the #RSF18S fuel line assy. for 69 302 Z28 / 70-72 350 Z28 for holley dual feed models.i'm having a tough time sealing the fuel leaks especially @ the fuel block were a 3/8" and two 5/16" line come into it.is there a trick into assembling it like working from the bowls to the block or ??.all the lines are hard to assemble or to fit correctly.are these lines an exact copy of the originals or are they just a poor quality assembly.i like the look of the lines it gives the car that day 2 old school look i want. so if anyone has any answers i would greatly appreciate it [img]/ubbthreads/images/graemlins/dunno.gif[/img] [img]/ubbthreads/images/graemlins/3gears.gif[/img]

musclcar,
It can be like a puzzle--- Go carb to unsecured fuel block ---get the fittings started in the carb and the block and then start to tighten each fitting a little at a time until they are tight.-----If you have to do any shifting for position ,you will have to back off on some or one of the fittings to give you play to secure fuel block.----You can use a light sealer on the threads(compatable for gasoline).-----If you don't tighten them flush to the seat they will leak,that's why tightening them a little at a time will give them a chance to seat properly---JoeG

would also running a edelbrock TM-1 intake and 1" spacer have something to do with it also.i got the bowl fittings to stop leaking ,but that 3/8" line that goes into the block looks like it's not lining up .there seems to be a slight gap between the fitting and pipe on one side that you can see from the fuel block.it almost acts like the 3/8" line is to short or not bent properly.would snugging up that line to the block then tightening the lines to the bowls help.oh i almost forgot i'm also running a set of old cal- custom finned valve covers,so if i take the spacer out the 3/8" line looks like it may come in contact with it. thanks though for the info [img]/ubbthreads/images/graemlins/3gears.gif[/img]

[img]/ubbthreads/images/graemlins/grin.gif[/img]--You did't say that
TM-1 mounts the carb on an angle right plus you've got a 1" spacer----the fuel block set-up was made for the factory setup---just use the chrome 3/8 dual fuel line set-up from Holley---Thats what Motion used.---JoeG

I had to tweak the float bowl lines to get everything lined up. Stainless can be hard to get sealed up.

i've got another dual feed line laying around i'll put that back on,but i really like the looks of that other fuel line.you said motion ran a dual feed ,did they run alot of rubber hose.do you have pics of a sbc with a close up of the fuel line routing.what about running two lines off the carb to a regulator then to the pump.i remember seeing something like this back in the late 70's.i'm just looking for that classic high peformance look and i don't like braided line [img]/ubbthreads/images/graemlins/3gears.gif[/img]

musclcar,
Didn't mean to mislead you --my second comment was aimed at the bracketed fuel block that gets bolted down(Your 1" spacer would throw it off).-------If you have just a fuel block without any brackets then you will still have to play with the lines or tweek them as Keith T. said----after some swearing and cursing it should go together---JoeG [img]/ubbthreads/images/graemlins/beers.gif[/img]

Go to the B/M site I put up a web--scroll down to engines,you will see the dual feed gasline. Everybody used rubber gas line connections back then. I kept mine in as it came from Motion(new rubber gas lines of course)----

thanks JoeG well after about an hour of intense concentration and a few choice words said out loud it went together . i found out the thick aluminum gaskets that go between the bowl and the fitting don't seal to good.and i did exactly what you told me to do,the fuel block is not bolted down it floats.i also never new the TM-1 had the carb slightly angled until you told me and i can now see that,again thanks for all the info [img]/ubbthreads/images/graemlins/worship.gif[/img] [img]/ubbthreads/images/graemlins/worship.gif[/img] [img]/ubbthreads/images/graemlins/beers.gif[/img]
