[Tigers] cross over hose plus other questions...

Mon Jun 12 17:51:40 MDT 2017

Good day, Gary! Always glad to hear from ya.  So, black hose of some sort.  I will measure the hose barb OD tomorrow before I head down to the local industrial supply and see what they have for hose.  And I will get about 10 feet of the stuff whatever it is. I have a lot of hose clamps. 

Let's chat about slow filling and fuel spillage on the car fender's paint. Stop That!  I guess we need to first figure out what the issue is that is causing the slow fill and blow back maybe. So, lets thing of all the things that can cause a slow filling and the consequences of that.  What if the driver's side tank cannot vent as fuel is being put into the tank? If the vent hose is kinked and air cannot escape then pressure is going to build up in that side and it will not fill very quickly. That sound correct or likely?  Next is maybe the I think I could make a case for removing the D side tank hide panel and remove the hose from that barb to see if that cures the problem. And since the P side tank is getting the full flow of fuel, than perhaps it is causing some blow back into the recovery system. More than it is designed to take?  Does it need to have a tight seal to work? Been a long time since I bought gas in LALA land. And if that  system works when you have adequate venting from the tanks, then maybe you need a big old solenoid valve to dump the fumes from the tanks into CA's finest air.  So a solenoid around the P side fill hose in the underside of the fender, with a new dump position might help. And maybe get ya thrown into jail if someone snitches on ya. A simple T in the fine with the valve on the middle leg would work, dump it under the car or maybe even into a vapor recovery canister from a junque yarde donor.  Are those cheater devices that let you seal off the recovery part of the fill hose available anywhere? Heck, I would make a simple one and try it some midnight when no one is looking. Some kind of grommet to seal the fill to a bag that can be tired around the recovery hose. See how that works. And run when the California Climate Control Cops come... very fast... Check in Hemmings? Maybe the old car folk have a solution already.  Next is a possible rats nest in the cross over pipe? Got any old rags down there from when you might had had all that stuff apart? Slow is ok for running but filling is not  when the pump is dumping at warp nine. Maybe look for a older gas station that might have a slower system. I know some stations have pump handles and pumps which can put a lot of fuel  into the tanks in really short order ...useful for Motor Homes and trucks on gasoline.  I think you get an older pump system that is not pumping 5 times the rate as the ones you have been going to. So go to older gas stations that look derelict and ready to fold and go under, lol.  If pump flow is the issue I do not know why slowing it down with the handle does not work. 

Anyone else have this problem> I live in Nye County in Nevada and we have zero climate controls here.  

Interested is seeing what the solution is myself.

Hi Mayf
It should be black rubber hose, and I'm pretty sure it has clamps.
Humm,  my P side rear fender was hit too, once before I got it and my boo boo required a whole new fender  ;-)

I think you can get the sender out, may need to un-bolt the tank and 
rotate it slightly .   A lot easier with
the tank out though.

To get rid of the smells, get rid all the old rags and stuff   ;-)

Hey, Mayf.   While you are thinking of gas tanks...
I have the worst time forcing gas into my Tigers around here with the vapor recovery gas pumps.
I am not really sure what the problem is, but I end up with gas running down the side of my Tiger and it is eating my paint!

I am thinking that an open vent on the driver side would help.  Then I could jam the nozzle tight with the inlet which really makes a mess if I do that now.  Even if I pull back the recovery part and hold it like when I fill small portable tank for the lawn mower doesn't work unless I really barely drip it in, and then my hand hurts before I get even a couple gallons.

Very occasionally I get a pump that will let me push it in tight and pump it quickly with no spill..  Is that a good pump or one that's really broken or mis-adjusted?  I think the later because it is so rare.
