MY vac gauge for telling me if i am using gas or not the one that has red yellow green and when in green it uses less.
since i add my new fuel pump it never goes in the green now. Does that mean i should take it back off. I put it on because
i thought when i do in the hills it would pump better from the crazy take design that goes out when you are low on gas.
THe pump is up front next to the engine should it be back on the frame in the middle by the generator line connection?
any ideas on whether i am going to die or not.

Yes, You are going to die.
...Someday, unless you are blessed with eternal life.
Actually your electric pump should not cause you to use more fuel unless it is over-pressurizing your carb float, and then you would probably notice that. Perhaps no longer having vapor lock you are able to insert your foot in the carburetor more deeply, and that will cause you to use more fuel. I know when I "feel" vapor lock coming on, I feather the throttle until it "goes away."
I have not installed an electric pump yet, but will probably mount mine in the frame or use an in-tank setup.

thank you i thought so.
between now and then my vacum gauge seems to not work with the new fuel pump or at least it does
not go in the green ever now. WHich means i am using a lot more gas. it is way down in the red now
it use to when i backed off with no electric fuel pump go into the green. this means more money for
the dinosars. and thank god for the meteors or they would not be there for us to ride them even though they are now liquid.
I think i should take the pump off and see if it goes back in the green again. or have a switch for hills only or vapor lock times.
any one have a brainy idea from experience that would tell me what to do.

Last first - yes, you're gonna die one day.
I'd put the electric pump in the back.

An electric fuel pump should be as close to the tank as possible. They are designed to push fuel not pull. The further from the tank it is the more chance of getting vapor lock.

It has colors, bad gas, fair gas, good gas, it never gets out of fair gas now, before the pump if i for instance let off the gas
going down hill the gauge would go to good gas for there would be no gas used it now only stays at fair gas at the same
point.. I wonder if there is a leak in the new gas pump now that you say that. IT was placed up by the motor. I thought it was
going on the frame just past the terminal of the tank switches. It was put up at the engine. I think i better redo this and put
'
it back on the lower frame. or take it back out and keep the regular pump of the engine again. I think your right miguel's son
did it and i was told it would be by the lower frame by his dad and he put it up by the engine fuel filter, I needed to get the thing
out of there i had been there a long time getting things done - so i have it now and it is running good
but seems like it uses more gas. But i think i need to redo it back to the lower frame for if it leaks by the engine it
is a fire interest. more so than at the under frame. I have just stored it at my storage and i will study it when i get time.

Mickey, we have added fuel pumps in front and in the rear, we told you we would install it up front because you wanted easy access to it, and also easy access to the filters, so, we did only as you asked, the fuel pump we use is not the carter pump, we use a sucking pump , a pump that sucks the fuel and does not need to be feed in order to push fuel.
the pump we use is a full flow pump, which means, on or off, the fuel still flow thorugh it, unlike the carters, they must run at all times, so, you have an option to add a switch to it so you can run it or not.
we do not add this switch so , if you crash, it will not continue to flow fuel, we set them up so, when the motor turns off, it dose.
i , once again, have added many, and i mean alot of fuel pupm up front, and it is nowhere near any engine heat at all, in it bolted to the idler are mounting bracket.
now Mickey, if you remember, from the moment i got your motor home, i mentioned to you how bad your vacume is, and, if you recall, i told you, i am not so sure it is the motor as i feel it is your gage, but you told me, looking at my note, (yes, i do take notes to refer to later)you told me not to worry then about it for the moment.
and, for what it is worth, the fuel pump we use is a pusher pump , @ 5 to 9 psi, not, you are not going to burn up more fuel than you right foot is going to make it burn.
Micky, i hope this clears up your ?'s, however, please bring it back and we will move it to the read, inside the frame along with the prefilter then you can lift the gmc as needed to change the filter as needed. " NO COST TO YOU "

Thank you, i am happy with it all, and i take notes as well. But i would like a receipt for it all to put in my records if you get time.
You found the vacum hose was off the trans and that is why it stuck in low gear. thank you for that. I am happy with it all
and the vacum gauge is maybe because it is a mickey mouse rig. Joke. thanks miguel. i will talk with you latter, i am happy :-)

oh, mickey, i normaly do not do this on here but, when a can of worms is open, i feel i need to reply, per our call on thusday, last week, you told me the son of the po, who sold you the motor home told you there was a feul pump already up front on the frame, when we check, and i mean, we checked all over for an electric fuel pum, i called you to inform you there was none, yet you insisted the son told you there was, i t6old you, plz come over so you can show me where it is, you told me, he said it was on the frame up front?????
this is why you told me to mount it there!!!!!!!!!
the fuel pump # is E8012S, it has a built in check valve so your fuel does not return to the tank, it makes for a little faster starting

mickey,
one more thing, you asked me to check the onan, which i did and i told you, it was simply that there was not enough fuel for the pick up tube to feed the onan, how we check this is, we lower the left side of the gmc all the way down, which will move all the fuel to the left rear corner where the pick up tube it. it started, i adjusted the carb, adjusted the output of the ac side and all way well, i told you that there is nothing wrong with the onan, my son now tells me, you mentioned to him that you wish we had serviced the onan???????.
the oil was fresh, all seemed fine, is there something we missed ?????

no you have done a great job and it is my miss understanding. I am sorry if you think i am un happy i am not. it all works and
you have done a great job. I missunderstood you and thought the pump was going on the frame when you pointed at that
hole in the frame on the one that was on the lift and stated that is where you bolt it into. That was the last we talked about
the pump and i thought it was going there. It did not we were in a hurry, i am happy it all works i have another idea to put it
like rob states for aux only and put the pump behind the switch in the future. Then my gas vacum will go in the green
at times when on flat road. IT runs great, i have filled to tanks it was half full when i picked it up only took 20 gallons
this must have been the back tank being low as you say for the onan. I am very happy so please forget about me and the
whole thing email me a receipt for it all mickeysss@me..com thank you i have to go to work now and say hello to your son
for me. best regards mickey.
