Fuel line help
 

Where are you guy's buying your fuel lines? I need about 4-6 feet of line to reach my gas tank. Since the 5.7 is TBI I know I need high pressure. What do you guy's recommend? From the TBI to the frame is steel braided and it's solid line all the way back to the filter. I'd like to run the steel braided so I can run it along my step notch to the tank. If possible I'd like to get it premade. Any suggestions on who has the good stuff?

NAPA auto parts, you will have one coupled joint to run from the tank to engine. They have various lengths up to about 6'. You might be able to get by with one piece. Each piece comes with fittings and flare on each end.

I just got back from 3 Napa stores here in town with no luck. They offered me break line but the fittings are different. I'll have to check Napa's online store.

We have acquired a aircraft supply place called G&J in Ontario CA it is a drive for you but they have all stainless steel fittings tubing braided lines and AN fittings. We will be using them for our Fuel and Brake lines.

Local speed shop or JEGS or SUMMIT on line. Call and talk to a tech person explain what you want and its shipped to the door correct and on time.

G&J will have whatever you need, they're good guys. I bought braided, brake lines and all the AN fitting I need from them.

Do a search for "Industrial Hose Supply" or "High Pressure Hose" on Google, be sure to add "Bakersfield CA". I came up with a few that looked promising. But.....I'm on the right coast and have no idea what's close to you. We have a company here (Hampton Rubber) that makes all that stuff while you wait. I'm thinking you can find a similar outfit out your way.

Not that over building is a bad idea, but TBI runs at less than 15 psi. You can use nearly any fuel hose. Jegs and summit have great selections, but speedwaymotors.com has less expensive stainless braided and fittings of their own brand.

Shows how much I know. I always thought F/I hose had to be high pressure. I found a guy on Ebay with all three lines, 10' long. It's not steel braided but should work.

I have shortened the original steel fuel lines using my double flare kit like I do for brake lines. chev 3600 is right TBI is 15 psi, TPI, MPI AND CPI is 35 to as much as 65 PSI, I hate to admit it but I am using the original plastic(nylon) fuel line from the donor car on my truck, I used a a line kit dorman sell's to shorten and ad two 90's to make it work.

I owned a place called G&J auto repair in Missouri, a few times companies I dealt with asked me if I was G&J aircraft.

Re: Fuel line help
 

Have you considered using the OEM style plastic fuel line?
I used the OEM lines from my '95 Impala SS donor so the lines just plug into the fuel rail, both sides of the filter, the fuel pump and I bought a fitting for $6 to connect to the tank.
Makes installation a snap, literally!

I'm doing the same sort of thing... using a TBI on my 350 and looking to overpressure it to 18 psi. Most of the factory or replacement pumps for the TBI barely, if at all, can maintain the correct 12-15 psi pressure, apparently. To this extent, I'm using a junkyard found pump from a late 80's F-series F**d that's capable of much more. Using a custom fitting from the pump to the filter and then the steel braided line to the TBI. There's a guy on ebay that sells the 18 psi spring that I need (not the point) but in using that pump, it's just brake line from the tank to the pump with hose connections. This is on the suction side of the pump and doesn't see any pressure, just vacuum.

TBI is really a low pressure system, so I wouldn't fret too hard on what you're going to need for fittings. Most industrial hose supply places that make lines for the big trucks should be able to fab what you need to your specs. The hardest part may be getting the correct fittings on the end that you need. Just bring the ends if you have them to match up or what they need to screw into and you should be good to go.

The central port injected 4.3 s10 engines run up to 65 psi to open the poppets on the spider injectors, your TBI regulator should return excess fuel pressure.If you want more fuel from a TBI you might consider injectors from a TBI 7.4 B.B.C.I cant remember the exact specs but they flow like 25 gallons while a 350 is 20 gallons an hour,Sorry its been a few years but I swapped a 87 305 TBI onto a 81 Chevy 350 and had to upgrade to the 350 injectors to make it run right, I did a bunch of figuring out to figure it out.I really like the TBI its a very simple system and hard to beat.

Re: Fuel line help
 

While this is true, I'm not running CP injectors... just the early (91) TBI model. The specs on the pumps are just enough to cover the pressure required and so any wear or age on them brings it below spec. I understand the return system as well, hence the 18 psi spring. For my application, the 7.3 TBI injectors are too big and would require less pressure (there's a site that specs psi and gpm's), optimally, the 9C1 cop car injectors would be the best and even if I could find them here, I might as well buy the ebay ones... and at about $200+ a set... just not in the budget.

Cheers,
Ted.
