> Hello GMC's
> Fixed the vapor lock problem?
> We will see.
> Ordered in a new FI fuel pump from Summit over night shipping to our sons home
> Excellent service from Summit
> A lot better then Jags who gave me the business about my cc at my home address and shipping to son here in a Denver
> Get out and get under for me.
> When I pulled the old pump today fuel ran out the intake end of the old pump "2 years and about 5,000 miles" from what I could tell the hose between the fuel filter and the pump end of fuel pump was leaking
> More like a drip
> When trying to pump fuel from the tank you would introduce a lot of air
> Causing the same problems as vapor lock "air locking" the fuel line or leaning out
> The hose was a little dry and hard.
> I replaced it with CG approved hose.
> We ran CG approved hose forward of the pump a year a go.
> My diagnosis is when the fuel got hot we started sucking air in the the fuel system?
> We will see pulling out of Denver west on I-70 this week after our visited with our don and family.
> Still not sure why when we stopped and cooled down we could run again?
> Not good but we could keep going.
> Running Howell TBI with older Holly TB for about ten years
> 74 Canyon Lands
> Thanks for all of your input.
> Questions let my know
> One bum showing the other bum where the crumbs are.
