I need to properly route the underhood fuel lines on my '66. Someone ran the feed line to the pump, but capped off the vent line. There was no fuel filter when I got the car, I am assuming that I should have a filter with one outlet to the vent, I put on a simple inline filter for now but I know I need the vent. The car is factory A/C, 401 motor. Anyone know how it's supposed to be set up? Thanks, Artie
Howdy, You say they capped off the vent. Is the line still present down on the pass. side frame rail? You need a cannister filter with 3 ports, from your local parts store. The fuel line comes in at the lower drivers frame rail, and doesn't quite make it out. Put your new rubber line on it about an inch long, then route it through the two "eyes" on two of the front of the oil pan bolts. Then run it up to the filter, which sits in a steel ring up on the pass. front of the motor. Run a line to the carb and then another to meet your vent line. I think the filter should be marked as to which line vents. Hope this helps. Dan
If I may add to this.....most of the aftermarket filters have a smaller diameter and don't fit in the bracket properly. I think you can get the correct ones from year one.:bglasses:
Run it to the fuel pump first! ...We know you meant to say that Dan! The vent line helps prevent vapor lock in the fuel supply line. The non a/c cars didn't use a vent line.... My first pass down the 1/4 (1981??), resulted in the car running out of gas halfway down the track due to vapor lock....Hate when that happens!:rant: Artie, did you make it to Atco yesterday?...it was a FINE day to go drag racing!
walt said Walt thats not quite correct. my car is a california non a/c car and it has the vent line. Bob
The steel line that feeds the pump is routed correctly, but there is just a rubber line from the outlet straight to the carb. The steel line is coming out of the frame, but some ****ing moron put a bolt into the end of the rubber hose with a clamp around it at some point in this car's lifetime. I didn't run the car yesterday because I was getting a fuel starvation problem that I noticed on the highway when I had the throttle wide open over 120 MPH. I noticed that there was more vapor than liquid in the clear fuel filter I have on there now so running the car would have been pointless:af: I figure once I get the lines straightened out I will get rid of the higher RPM surge. The track is open Wednesday night for test&tune so if I get this straightened out I'll be making some baseline runs.
Forgot to add, it's a new fuel pump on the car. I have also noticed there is no bracket for the filter on the engine or anywhere underhood:ball:
I have a new replated one but it's the type that attaches to the thermostat housing.....'65 style. Send me a PM if you want it.:bglasses:
Here's a fuel filter for it....Dan http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=34198&item=2465727320
Artie, I have an extra filter holder for a 66 GS. If you still need one you can have it. I can send it with the column, just let me know. Bill Sangster
Artie, you might want to check the mesh 'sock' over the fuel pickup in the tank....maybe it's restricted.... I went to an electric pump after my first racing mishap....never had a prob with fuel delivery after that.... Do you really need enough fuel for 120 MPH??? Atco is only a quarter mile long!...or were you heading to Dover?....
