He filled a 44gal. fuel tank in a truck with a fuel pump going bad!!! WTF. he`s an idiot!!! time to find a new boss.

 

yes.... yes he did... filled it on his test trip to see if the new stick coils fixed the problem..... they didnt so now theres a new fuel pump coming with a full tank of gas ...... will prob. start that project tomorrow....... hopefully i can pump the gas out once i have the filler tubes outta the way...

 

yaaaa doing fuel pump today...not nearly as bad as i figured it would be... just need new pump from boss and figure out how pump is held in place so i dont break anything....

 

WOW other than the moron designers designing the fuel filler setup like a bunch of freakin morons the tank was cake work to drop out....oh did i say the designers where morons ?? lol
pumped all 40gallon out with a little electric pump he has ... took about 20mins or so....8 4 gallon gas jugs later and it was almost totally empty... actually pulled the pump cap and sucked the last gallon out so i didnt have to deal with any gas around the pump..
will have new pump on tuesday and tank will go back in.... stupid gas filler will be the hardest part....

 

ok so boss got wrong pump to start with (48 state instead of CALI model) so had to wait one more day. CARQUEST got the pump in overnight for him. anyways got it in today in no time flat and it works perfect now , hot or cold it dont matter....
THANKS FOR ALL THE HELP GUYS !!!
only thing i noticed though was that it still only gets to 30psi fuel pressure..... should be 38+ from what im reading... that a bad regulator ????

 

This was like waiting for the final episode of Lost. Good to hear you got it all sorted out.

 

..... ya tell me about it... so whats your though on the 30psi ?

 

The specs for engine running is 28-45psi, KOEO is 35-45psi according to the shop manual so it's within spec. I think the earlier spec I gave you was for max pressure if the pump test is activated by a scanner. If you feel like it you can check the vacuum supply to the regulator for any leaks or if it has fuel in it.

 

ok thanks...
ok its within spec KO but KOEO its still low... it does hold pressure very well though.. really doesnt bleed off 30psi after getting there....
since its running OK right now ill leave it alone and just hope its a crappy pressure guage we have (harbor freight) it def. comes up to 30psi alot quicker than the old pump...

 

Good to hear it

 

I was wrong when I thought that I have fixed this problem when I posted about the vapor recovery lines. (All thought, The collapsed vapor line probably did need replacing.)

I did finally figure out that it was related to low fuel levels. After spending may weeks playing stump the Mechanic I was able to get a Mechanic to measure the fuel pressure when the truck started to show the symptoms. The fuel pressure dropped from 30 PSI to 9PSI. Bad Fuel Pump.
Replaced the fuel pump and the truck is running much better.

Sorry for my bad post on this issue.

 

its all good sierra... like you said it was 3$ and an hours time..... process of elimination with these kinda problems... bosses is fixed now with a new fuel pump also....
