Fuel system help needed...
 

I am considering converting my fuel system over to electric.
I am totaly clueless, as all I have ever had has been mechanical.

Will this kit from Summit Racing work on a 72 pickup with a 350 pulling about 400hp?

Yes, that will work. It is a little over kill in my opinion. I went with a mechanical fuel pump on my 383. It is the highest flowing pump holley offers with out haveing to use a regulator. Have not ran my truck yet. But it should be enough to feed my 383. It is going to be around 450 HP.

i don't see any advantage of useing an electric pump at close to $300 over a good mechanical pump at$50

I agree with cdowns on this, an electric is way over kill not to mention the extra noise your gonna have to live with. Most Good mechanical fuel pumps will work fine even for off road use and some serious HP.

Nascar uses stock design mechanical fuel pump for 800+ horsepower. ;)

Well then :)

I guess I will go with the mechanical fuel pump. But, I would still like to change over to the braded fuel lines.
Can anyone tell me what size the fitting are to the tank?

Thanks,
Nick

I tell you what I did. I used the factory fuel line from tank to pump. Then from pump to carb I used Areoquip socketless hose and fittings, I mounted a fuel block to pasanger side front fender well, came off of fuel block with two line over the top of valve covers to carb. I have a 750 holley HP series carb.

the fuel line I used is an -6 , forgot to add that in my last post

Well, the main reason that I am needing to rebuild my fuel sytem is because there are rubber lines from the tank to the pump. They are not looking so good, and I would feel much better with a quality line replacing them.

I was hoping that someone on here has done this before, and would know the correct size fittings that I would need. I have to take my seat completly out to get to the fuel lines from the tank to find out what size they are.

Thanks for your help,
Nick

your not going to be able to replace all the lines from the tank with braided they are steel lines coming off of the tank under the truck it switches to rubber then goes back to steel line along the frame rail

So, would I just use a clamp to connect the braded line to the steel line?
That doesn't seem like a real clean way to do it.

Buy a long stick of line and bend it up yourself. Connect the pieces with short sections of rubber line.

6 cylinder and 307 trucks used 5/16, the rest used 3/8.

you cant clamp braided line it wont seal its too stiff you have to use an fittings
