Awesome video man, This is hands down the most simplest video I've watched & i have watched many. Appreciate the straight forward approach no bs talking.
On a 1999 LS engine fuel tank, here's what you're looking for: - Purple wire: This is typically the fuel pump power wire. It supplies power to the fuel pump when the ignition is turned on. - Gray wire: This is usually the fuel level sensor wire. It sends a signal to the fuel gauge on the dashboard indicating the fuel level in the tank. As for the fuel lines: - 5/16 line: This is usually the fuel return line. It returns excess fuel from the engine back to the tank. - 3/8 line: This is typically the fuel supply line. It carries fuel from the tank to the engine. The third line is likely the vent line, which is usually a smaller diameter (like 1/4 inch). It's used to vent the fuel tank and prevent pressure buildup. Please note that these are generalizations and wiring/lines may vary depending on the specific vehicle and manufacturer. Consult a repair manual or a trusted mechanic if you're unsure.
I am converting a tbi to carb and considered using the factory in tank fuel pump. What would be the best way to plumb it? The truck was stripped of fuel lines and I bought a new 20 gallon tank to install. Will run just the one tank. Also, will I need to use a fuel regulator with bypass, the in tank pump is min. 14 to 25 psi?
Would have been good to see what the niggle was with the AN fittings. You can bet someone else gets the same problem and wont get the solution from someone who solved it.
I see you used the corvette filter/pressure regulator. Will this work for a 99to03 intake with the regulator on the fuel rail? I wanna use this setup but without the AN fittings on the tank side. Only on the feed and return on the rail crossover.
@@Juicesquaredchevy the blazer is actually a little easier as you don’t have to use compression fittings just some metric adapter fitting to make them into -6 but same fuel pump and filter will work as that is what I am using on my K5.
great video!! what did you tie your power and gauge wire into to give them power? did you have a new fuel pump relay harness or did you tie into something factory on the truck? i have an 85 c10 and looking for power sources for my swap
Why was my gas spewing out of the vent tube from the sending unit it did after my truck was warmed up after I loosened up the gas cap it stop spewing fuel
I just put a 86 305 engine/700r4 trans in a 1997 suburban 1500...should i replace the fuel pump in the tank with a 86 style fuel pump im stuck on how to run fuel lines to my carb..engine also came with a Posi flo electric fuel pump hooked up to the carb...motor is from 86 caprice
I’m putting an L 86 LT engine in 1986 K-10. Did you need to modify or change the fuel lines leading up to the engine bay? My stock set up was low pressure mechanical pump. I’m assuming the 87 was much higher pressure electronic
So did you just use the 87 fuel lines? I'm not doing LS on my 87, but doing a edelbrock pro flo 4 and it calls for this style pump. My question: is the factory fuel lines on my 87 with TBI acceptable for the pressure od the wabro 255? Or should I be looking to replace the hoses?
@@jasondominguez8179 The stock fuel lines didbnot work for me. There were some rubber hoses in the system that could not handle the higher pressure. I had to install a new sending unit and fuel lines.

I appreciate it glad it helped you out!
Thanks for posting this! I coming from you’re other fuel system video! Great work man!
Hope they helped you out!
Great video but Did you have to cut the bevels off the get the fittings on because I'm having the same issue
Yes they have to come off for the fittings to work.

Good info

Its amazing how much you sounds like David Newburn from Faster with Newburn and Cotton
One of my favorite shows to watch!
Nice video!
Thank you!

I appreciate it!
I used an fittings on mine but i used a different style. Didn't have to cut the end of the feed/return line
Right on!
whats the part number of the one you used
Thks for the video
You're welcome
Would have been good to see what the niggle was with the AN fittings. You can bet someone else gets the same problem and wont get the solution from someone who solved it.
I cut it to close the the factory beveled portion which swelled the tube changing the OD of it.
So I can use my 85 fuel tank but use these parts you’ve shown?
Yes, it just won’t have the fuel tray that the 87 has.
Do you have a part number for driver side?
Tank or sending unit?
So how’d you end up wiring it? Which wire was which? Is the grey power?
Purple is the gauge, grey is power.
Thanks!!
@@brandonbradley8918 no problem!

I'm not sure, I've always used a newer intake.
Can you just use braided kevlar hose with clamp over the fuel lines or do you have to use AN 6 lines
Im not sure on that. I would assume you could use clamps but idk know that answer for sure.
Great video by the way. I used it for my build. Your link for the fuel pump leads to an inline pump. Not an internal pump.
Where did you get the rubber "isolator" material for the tank straps?
Previous owner put it on, I’m not sure where he got it.
I have an iron block 6.0 I’m putting in will this work for that? I’d assume they all run the same pressure?
@@wyatterickson1289 yes sir
Are you going to put in a drivers side tank?
No, bed only has a filler neck on passenger side.
Would this set up work on a the blazer suburban rear mounted tanks as well?

@@3rdGenC10s thanks for the info!
@@Juicesquaredchevy not a problem.
Wonder if this will work for my 77 Monte🤔
Everything but the fuel tank should work for you.
great video!! what did you tie your power and gauge wire into to give them power? did you have a new fuel pump relay harness or did you tie into something factory on the truck? i have an 85 c10 and looking for power sources for my swap
The stand-alone harness I bought had a fuel pump relay to tie into for fuel pump power and I used the factory fuel level sending wire.
@@3rdGenC10swhat stand alone harness did you buy do you have Link
@@khoryhadnot PSI
Why was my gas spewing out of the vent tube from the sending unit it did after my truck was warmed up after I loosened up the gas cap it stop spewing fuel
Sounds like it’s pressuring up. Might try buying a vented gas cap.
I just put a 86 305 engine/700r4 trans in a 1997 suburban 1500...should i replace the fuel pump in the tank with a 86 style fuel pump im stuck on how to run fuel lines to my carb..engine also came with a Posi flo electric fuel pump hooked up to the carb...motor is from 86 caprice
I’d put a in tank pump if it doesn’t have provisions for a mechanical on the block.
I’m putting an L 86 LT engine in 1986 K-10. Did you need to modify or change the fuel lines leading up to the engine bay? My stock set up was low pressure mechanical pump. I’m assuming the 87 was much higher pressure electronic
87 is only 12-14 ish psi 3/8 feed hardline and 5/16 return lines is pretty standard for a ls swap
So did you just use the 87 fuel lines? I'm not doing LS on my 87, but doing a edelbrock pro flo 4 and it calls for this style pump. My question: is the factory fuel lines on my 87 with TBI acceptable for the pressure od the wabro 255? Or should I be looking to replace the hoses?
@@jasondominguez8179 The stock fuel lines didbnot work for me. There were some rubber hoses in the system that could not handle the higher pressure. I had to install a new sending unit and fuel lines.
You could use the hardlines but the rubber would need upgraded as they wouldn't be rated for the efi pressure.
Does your pump constantly scream?
No the intank pump is quiet.
@3rdGenC10s mine is in tank and louder then shit. Since day one
I can hear mine faintly when I turn the key and it primes the system.
Is it the same as the driver side tank?
Can you make a wiring video
I’ll try and get one made when I get to that point
Can you give me the part number of the fuel pump base?
Driver or passenger side?
Passenger side
FG05M
Aluminum compression fittings should NOT be used on steel tubing. I guess the Chinese manufacturers don’t know that !!!
Good looking out.
A how too video but skips the part of doing it!
@@ScramblerGuy feel free to make you own video. I would love to comment on it.
@3rdGenC10s i wanted to see how it went together but you skipped it.
