Prolly electric and frame mounted on your truck...could be in the tank too. /forums/images/graemlins/dunno.gif
The mechanical lift pumps on 6.2's are in the same place as on a small block...although very hard to get to.

Yeah, remember that sound of a fuel pump I was asking about a while ago? I know there is this "frame mounted" pump right below the cab- I just didnt know that it was the *only* pump. (I thought it was just the helper).
I best get another pump I think. (as a spare). Also, I read on thedieselpage that these pumps are prone to failure, usually because of debris getting caught inside, and that a filter before the pump was recommended.
im thinking of just bypassing the model 80 standayne filter that I have, and fitting a permacool 2 micron fuel filter/water seperator before the pump. Is this a bad idea?

I put an electric fuel pump on my K5 on the frame just under the passenger side door. I also put a filter on the tank side. It has been on there 3 years and never had a problem. Of course I change the filter when i change my oil.

what kinda pump did you put in? I was just wonderinf if you could ever put *too* much pressure in the line. I was gonna use the standard TBI fuel pump in tank for my aux tank, but thought the 15psi or so it puts out would have been too much?

Higher pressure changes the timing advance unit operation, and it may be harmful to the lift pump inside the injector pump. I really dont know how much the timing would change, it may be negligible, it may not. As far as the internal lift pump, I do not know what kind of inlet pressure it can see without being affected, but if the factory wanted 6-10 psi or whatever, I would stick to that. The pressurizing valve in the injector pump should however set the max pressure in the system, but again, I wouldnt risk it, just use a parts store inline pump works from 6-10 psi or so.

how much do the elec pumps usually run? cheap - high i had an issue with the mech pump and its shaft had been broke. this found out after i bought the truck and havent had it running due to being last on project list atm and a cash shortage for my project list /forums/images/graemlins/doah.gif

34 bucks I think from Pepboys- I got a spare one from there two weeks ago. Generates max of 4-5PSI's, and up to 45 GPH.
