Can't seem to get gas to carb.

[JEEPERZZ]

my 74 jeep won't start I've put a new gas pump filter etc. etc. nothing!!! could the lines be clogged? The pump works is the second line from the tank that feeds into thegas filter a by-pass? its a 360 all stock down to the lug nuts. I'm dunmbfounded. also does any body have a schematic of the gas line so I can look at this is really pissing me off my wife said I need to get rid of my baby!no way help. :confused:

Looking at my new Haynes (old one isn't allowed in the house anymore) and says check for clogged fuel filter or lines or defective fuel pump, make sure tank vent lines aren't clogged, check suction hoses at the tank and pump, if they're cracked may not allow fuel to the fuel pump, check for clogged screen on the pickup in the fuel tank... That second line may be your vapor line... guys here with alot more experience than me should be able to help you through...

The second line from the filter to the tank is a return line. Check for a broken or cracked feed line.

Lookin at my 80 chero, there are two steel lines coming from the tank, the smaller diameter of the two is the return line, and the larger is the supply line. The supply line goes to your fuel pump and on to the filter. Make sure you have the filter positioned correctly. Main line in, and then center line out to the carb, and the return line out to the return line steel tube. Hope this helps and good luck with the significant other too. smile.gif

JEEPERZZ,
You can figure this out, start by just taking a gas can and seeing if you can get gas straight from the can. If so, work back towards the tank adding in a section each time. Mine goes from (back to tank) the pump to 5/16 fuel line, to metal line along frame, to more 5/16 fuel line, to tank. If you can pull gas through all the connections and have nothing left to check but the internal parts of the tank. There is a small fuel sock - wire mesh filter at the bottom of the supply tube inside the tank. Mine was completely corroded and the supply tube clogged at the bottom inside the tank. If this is the case any competent radiator shop can cut your tank open and clean and replace the sock and or tube. I chose to do mine myself, took about 10 hours and cost me about $100. The radiator shop choice would have been cheaper and faster. Replacement tanks are available from Raybuck.

Had similar problem about two months ago. I had an intermitent problem for a couple weeks then no gas at all. I put hose in a jar of gas and pump worked fine (I did this after replacing the filter and making sure it was ok) so I started tracing the problem back to the tank. Hoses were good so I dropped the tank. Not only was the sock torn and a lot of debris on the bottom of the tank but there was also two wadded up balls of aluminum foil in the tank that had obviously been there a long time. I cleaned the tank out and even calibrated my sending unit so now it reads over the full scale. Put it back in place and (after installing a new sock $10) problem is fixed.

Good luck

I'm working on the same problem right now. My problem was intermittant at first, so I cut in a see thru glass filter just before the fuel pump. This kept clogging with fine red particles. Then it clogged with large rust chunks. I just got my new poly tank today, but I am sure to need a pickup tube screen and possibly a sending unit. New sending units, pickup tubes and poly tanks are available from MTS Company. Their web site is www.mtscompany.com (http://www.mtscompany.com) . I called with a question, and found the owner Mike to be very helpful. I bought the tank thru J.C.Whitney, but they do not carry the other pieces. I found the company from the install info. Their # is 800-522-1622. I'm not affiliated with these guys, but it seems like they have a lot of good stuff.
