I need to replace my fuel line after the carburetor upgrade

[TheDude]

Hi,

My improvised fuel line is not going to hold up after the 2bbl 5200 carburetor upgrade. In this picture you can see how I used rubber hosing to extend the fuel line. I cannot clamp the hoses tight enough to make a leak free seal so I must replace the entire fuel line now. This way I can route the line straight to the carburetor and not follow the route of the old 1bbl carburetor setup. What size and type of fuel line do I need for my 1968 200ci I6? Do I need a specific tool to bend the lines? Would the fuel line go directly into the carburetor or do I need a special connection?

I guess I should get a new fuel filter as well. Can anyone recommend a good fuel filter?
Thanks,

Justin

P.S.

I am still waiting for the new spark plug wires but I have started the engine with the old wires. The engine fires right up and idles smoother. I could not be happier...unless my wires arrive soon. :roll:

I am using a autometer -4 gauge line for my fuel line (have been for a couple years now) got is from my local speed shop for like $30 with fittings. you will need a inverted flare fitting for the pump but everything else should be included in the kit. (on the fairlanes the filter is remote mount so I just drilled and tapped it for a 1/4 npt fitting) the -4 line is pretty flexible and abotu 30" or so long so you can route it around the back of the motor for a cleaner install.

while you are at it...put a see thru in-line fuel filter before the fuel pump. I got mine at discount auto

easier than if something gets into pump from your tank.

i never though of going around back with the line. I will probably wait till I get the 2bbl...

are you using a single diameter pipe to adapt from the larger diameter hose to the smaller diameter hose - the latter smaller hose i refer to is the one that hooks up to the carb?

from a good hardware stores you can get barbed adaptors that will allow you to link those two hoses up with no leaks.

I bought a steel brake line that threaded right into the carb via an adapter. I bent it with a bending tool and routed it into my electric fuel pump and then into the new threaded fuel filter.

the bending tool can be bought anywhere for around $20 and is really gratifying to work with. I replaced all my rubber lines with bent steel ones. The adapters come in many sizes so after some troubleshooting, you should be able to thread it right in. The lines are less than $5 and the adapters are mabye $1 or $2.

evren,

The connection between the larger hose and smaller hose is fine. I am using a plastic barb to connect those hoses. No leaks there! 8) The leak (I should have specified this) is occuring where the fuel filter meets the large hose. The end of the fuel filter is threaded so it is made to screw directly into the old 1bbl carburetor. I slipped the hose over it and clamped it as tight as I could. I tried to put clear silicon around the end of the hose but the silicon will not hold up to the high temperatures.

I am hoping to replace the fuel line with the same size stock line so I can hook it up right to the fuel pump and not have to worry about adapters. Although, I will probably have to find an adapter to hook the fuel line into the carburetor. What is the stock fuel line size for a '68 200ci?

Thanks for the help everyone,

Justin

I always heard it was a bad idea to use break line for fuel lines because it would leak.

Maybe that's just for EFI operations with higher fuel pressure.

I haven't had a problem and I only used single flare ends too.

if you go to a good auto parts store they should be able to get you a clear filter to replace the stock metal one that screws directly into the carb. that one will have type nipples on each end. i went to napa and just asked for a clear fuel filter that would hook up to 5/16 inch hose (i think that's right) on both end. the guy just went back and found one. some places need a year and model number to get you anything but this napa was good like that. at least for now you could just use that.

if you really want i could try to find the part number for you.

If it is not too much trouble that would be great. If you need to dig through old reciepts then do not worry about it. I usually go to the local NAPA store which is quite small but very friendly. They have great prices and always have what I need. If they don't then they can usually get the part to the store on the same day.

Thanks!

i put the inline one in before pump becaus eof the shi& that could come from our tanks

so I have two filter...two are better than one

i'll try to find the box. it may take a couple of days cause my car is not kept close to where i live. but if your in a rush just give napa a call and tell them you need an inline fuel filter with 5/16inch or whatever hose size you have ends and see if they'll just go find you one. napa's around san diego were good shops. but i'll try to go by the garage and get that part number for you as soon as i can.

Hey dude!

I put a clear inline filter just before my pump because i have not cleaned or repalced my tank and I want to catch sediment and junk before the carb. The clear unit helps me see what I am getting at the carb.

From the stock fuel pump I am getting about 4ps average. I have been told this will be less as the pump wears. Down around 2psi and I will expect to have some problems feeding.

As for your setup...I would not go around the front of the block near the fan but go back towards the firewall and loop around to the carb. You should be able to run a solid line from the pump to the carb. (Shortest direct route) If you have problems with leaks then use a brake flaring tool and put a bubble in the end of the line where you expect to attach your hose line.

probably took me too long but here it is :

NAPA gold filter #3011

i think that one is 5/16 hose on each end but check it out when you get it.

sorry it took so long.

I just went to NAPA today and got it. Thanks.

Justin...switch over to a metal line and save the rubber for other stuff!

On my '68 with 5200 I installed a disposable Fram inline in front of the pump and then ran a rubber line from the pump straight up over the vavle cover to the carb. In this I installed a Purolator glass filter. The Fram does all the work the glass filter is just to be safe and I can always verify the carb getting gas.

I gor rid of that ugly setup. I replaced the fuel line with a metal line. I will make an Update post within the next few days. The Mustang runs now, it just needs to be timed and it needs brake fluid.

There has been much talk about using two fuel filters, one before the pump and one filter after the pump. I believe one filter would be fine. Would an extra filter (located before the pump) just slow down the flow of the fuel? If you are using a mechanical pump, you are not getting as much psi when using an electrical pump. Stock mechanical pumps are about 3-4 psi, correct? Wouldn't an extra filter before the fuel pump just slow down the flow of fuel even more?

I would like to hear some thoughts on this matter.
