Pump to Carburetor Fuel Lines, what are you all using? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

CastIron · 09-09-2015, 11:49 PM

I'm going to be installing a crate motor in my 69 C1500 in the near future, replacing the original 307. I will also be installing an Edelbrock performer manifold and carb that I've laying around for years. I plan on using an original style fuel pump, which I believe has a 5/16" inlet/outlet. I have seen a few different braided hose kits that seem to use a larger 3/8" hose. Ideally, I'd like to use all steel lines with an inline fuel filter. But who sells all the fitting I'd need? What are you guys using?

Stock metal tubing.

elkniks · 09-10-2015, 12:26 AM

-6 braided hose. Much easier to work with I think. Summit fittings are just like Russels and easier to use than Earls. Just make sure to use nitrile lined hose(not natural rubber)to stand up to "Obama gas".

Home bent tubing with a rubber jumper gas line by the pump.

Those A/N fittings and braided hose look great!

I have this job coming up and I am going to use 5/16" Poly Armor tubing from NAPA, putting in an inline filter (NAPA) with bubble flares and short bit of hose. I'll make my own double flares for the pump and carb fittings with a Craftsman Double Flare Kit.

Steel brake lines the whole way...

One nice thing about runnin a Q-jet is that you can use OEM replacement lines. Cheaper way is to bend your own steel lines but takes some skill or at minimum a lot of trial and error! The braided is the easier DIY and has the racer look to it but comes at a $$.

I recently got an edelbrbock fuel line kit with a braided hose, but the 90 degree adapter to the fuel pump doesn’t fit the fuel pump.

It is stock fuel pump on my 1970 c20

Any ideas on what the thread and size for this is?

I had the same line kit a few years back, my pump needed this 90 to adapt the pump to the line kit, your pump may be the same.

Yes!
That’s what I was thinking but wasn’t sure of the
Thread and didn’t want to pull it again .

Thanks!

I must say that is some work well done sir. I have been admiring your work for years on this site.

X2 steel the entire way. No point in have a 10,000 to 20,000 thousand dollar truck burn down from a 2 dollar hose.

Husker · 09-10-2015, 09:47 AM

Factory steel to QJet. Get a good bender it's not hard to make your own.

kingstrider · 09-10-2015, 08:48 PM

Steel brake lines here as well. The last thing I wanted was an engine fire due to rubber hose melting down.

hardwaycooke · 09-10-2015, 09:01 PM

copper coated steel/zinc hard lines.

**jocko** · 09-10-2015, 09:18 PM

steel lines, have fun making em too (seriously) - you'll be glad you did.

Hamjet - you mentioned you used brake lines. What size? Normal larger size brake line is 1/4" and I've always thought the smallest acceptable fuel line was 5/16" (with the larger cfm setups getting 3/8" lines). Love the W motor btw, looks great!

My local Advance Auto Parts had 5/16" lengths of brake line in stock. The 72" long one was perfect for my tank to fuel pump run.

Yup... bent my own with 3/8" hard line from my Carter pump to my Holley carb.

Here is the line on the bench.

Here it is installed.

Here is the tubing bender and flare tool I used to do it.

From the pump to muti-line fitting is 3/8". to each carb is 5/16". auto parts stores have all different lengths and diameters. Some I had to shorten and double flare. Thanks..

Not the best pic, but SS hard-line with an in-line AN fitting fuel filter.
