Fuel line problems

I've been checking the other posts and I am looking for a pic of a fuel line set up. I bought an edelbrock in line set up for my holley 650 carb. It has the two lines going into the carb, but the problem is that it's in the way of the Heater hose going into the manifold.

Also the alternater is close to the line so I have to put a 90* turn on it insted of running it stright into filter and mechanical pump. I was told that this could bring down my fuel pressure.
I wish I could post a pic of mine but I'm not sure how its done.
Thanks -the rookie

Re: Fuel line problems

There are lots of choices for fuel lines, you could surf summit for a week and never see them all.

Most intakes have 2 possible places to put the heater hose, one straight up and the other straight out. It sounds like you are using the straight up one, switching to the other is a cleaner look and gets the hose away from the fuel line.

Whenever possible, hard line from the carb to filter to mechanical pump is best, and they can be bent in a pretty tight radius.

Re: Fuel line problems

Thanks, I dont see the "stright in" inlet on the manifold. (edelbrok performer eps) but I do see another stright up on the other side of the manifold (opposite side) next to the thermostat. Its been blocked off with a bolt.
will the fuel line be Ok with a 90* bend?

Re: Fuel line problems

I used to run the suction side inlet to my fuel pump with a hardware store hard 90 fitting, all that would fit. Not the best idea for sure.
A 1" or better radius bend wion't restrict flow much at all.

Re: Fuel line problems

I've never been able to get them stupid after market inline fuel logs for Holley Carbs to fit my engines without having to cut them apart and modify them with hose and clamps; but must say once fitted work very well.

Re: Fuel line problems

Do not use the harware store 90s. They will cavitate on the inlet side lowering fuel pressure and volume. Look inside one of them. They way they are drilled is a problem too.

I made a 3" to 4" 90o by hand out of the aluminum line they sell at the harware store. That worked well. Now I am running a Victor fuel pump and have to regulate down to 7 1/2 psi/. I use the fuel regulator as a 90o.

Avoid any extra 90o bends.

Do not run your fuel line on the inside of the front frame rail past the headers. I had my stock fuel line heating the gas causing vapor lock like mad. I ran my fuel line outside the framerail past the headers and the car ran much better. Hot starts used to be impossible.

Re: Fuel line problems

I have the 'Aeroquip' fittings - one 90* comeing from the edelbrock fuel pump then another 90* at the duel fuel line connection. Think this will be a problem? I have an Earl filter in between.
Still trying to find the location to connect the heater hose. duel fuel line is in the way of the original inlet on the manifold.

The Aeroquip/Spectre/etc, radius fittings are the best to use if possible. If you can avoid them do so, the less the better. Straight line is best, but space and angles limit what you can do.
