Replying to: jimmurray1946 (Apr 02, 2007 11:30 am) Are you sure its the pump? Have you checked the inline pressure with a gauge? Replies to this message: jimmurray1946 (Apr 03, 2007 7:24 pm) hoodlatch (Apr 04, 2007 8:23 am)

Replying to: hoodlatch (Apr 01, 2007 12:30 pm) Hi,   I am in the same boat as the OP, with an 88 S10 blazer. Good point about burning down the garage, but the same applies to having to drain 30 gallons out of the tank, before I can drop it so I am curious as well, to know if the pump in the tank, will block the flow, or allow an external one to pull through it.....   The 200 TBI FI system only requires 9-13 psi, so I am guessing there are some reasonably priced external pumps that can do that, but of course, its not something a dealer would recommend   I would settle for buying a $50 pump that would let me drive the truck till the tank ran out, and then drop the tank and do it right, and at 16mpg, that wouldn't take much.......   From a safety pov, using the same signal line to turn on the external pump, would maintain the integrity of whatever else exists between the computer, the oil pressure, and the relays.   Besides, as I said, I would settle for being able to drive it out of gas. Dropping the tank is not beyond me, but dealing with 30 gallons of fuel, is actually bordering on stupid.... After handling that much fuel, it would take a week for the buzz to wear off, so I could do the pump!   Thanks for any comments or suggestions.   John Replies to this message: hoodlatch (Apr 12, 2007 2:39 pm) gonogo (Apr 13, 2007 10:00 am) hoodlatch (Apr 13, 2007 4:52 pm) and 1 more...

Replying to: singlewc (Apr 12, 2007 8:48 am) Have you crawled under it to see what all is involved to undo the bed and slide it over to get to the top of the tank? When I dropped the tank on my S-10 it had about 10 gallons in it which was more than I wanted to deal with. The next time, before I go through all that again, I'm going to pull the bed. While I have the bed off I'm going to make a removable access plate, something GM should have done from the beginning.

Replying to: jimmurray1946 (Apr 01, 2007 9:21 am) You would not be doing this lady any favors by trying to "rig" an external fuel pump. Your talking about opening yourself up to liability issues if an accident or fire should occur. The fuel pump is in the tank for a reason. This system operates between 50-60 PSI with a maximum head pressure of 80-90 PSI. You can get just the fuel pump, you just have to shop around. Then again you run the gambit of breaking the plastic module assembly. Search e(vil)bay, I see there's a butt load of them on there.   Doc Replies to this message: jimmurray1946 (Apr 16, 2007 7:59 am)

Replying to: drwright1 (Apr 15, 2007 7:55 pm) thanks, another avenue i hadnt thought of was e-bay. i have checked the local wrecking yards but was afraid to go that route.
