WTF

Question #4:

1999 Silverado. New Fuel Pump. Now it will not start.?

A some weeks ago my 1999 Chevy Silverado 2500 6.0 V8 died on the road. Troubleshooting determined that the render viscus necessary to be replaced. Fast forward to yesterday when I conventional the newborn viscus that I ordered from amazon. Specifically this one . The exclusive disagreement between the older pump and the new digit was the old viscus had the MP150 connector and the newborn one has the GT280. A newborn connector was included which required me to cut soured the older connector and splice on the new one. The command wires and the GT280 connector wires were luckily the same color so I had no problems there. I installed the pump itself without much trouble. Putting the lock anulus back on was a bit tough. I turned the kindling to on just to see if the viscus would engage, no good from the pump. Tried to start the truck, crank but no turn over. I made trusty the race and the fuses attendant to the viscus were ok and they were. Double checked the wiring and distinction connections which seemed secure. Not sure where to go from here. Instead of dropping the tank, I distant the bottom to prevent damaging the lines and making replacement easier. I wish this is sufficiency information. Any support is greatly appreciated.
Problem solved. The culprit was a grounding strap that goes from the viscus to the frame. It deal the same decamp as the strap that comes from the modify hose. I must've not detected it when I distant the bolt. Truck runs enthusiastic now.

Question #7:

electric fuel pump question?

i hit a 95 chevy jacket ,you crapper hear the viscus become on when ya invoke the key but wont start. was told to advise the release valve to see if its pumping gas, where is the regulator located? its fuel injected v-6 if that helps. whats the best turn to analyse for spark? thanks for some info

Question #8:

Weber DCOE turning - Having trouble with bog?

I am employed on a friend's '61 Mercedes 190 SL - 1900cc 4 cyl OHC engine, and it was acquired with threefold weber 45 DCOE's. It just would run soured idle, as it would majorly discontinue out. Came with a 30mm venturi and 115 fuel, 200 expose jets. Car is exclusive unvoluntary for pleasure, not racing.

I hit feature HP books on weber carbs, finished other research. I actualise the 45 model is not the prizewinning - a 40 would be better fit - but of course the 45 is adaptable, just we're on the baritone end of flowing for that model.

I have bought assorted jets, and set timing, valves. I modern timing some soured stock as that was said to be needed on high flow DCOE installation, and that helped some. The accel pump entireness and those accel jets were enlarged a size, that's not the problem. I get initital power from it.

I hit upsized the jets feat from a 115 to now a 175 and its loads better, but it still bogs on heavier throttle.application. I does pull a taste meliorate after 3500-4000. I wish I had set of 28mm venturis to try, but I keep throwing large jets at it. I hit after outlay loads on actualised jets . Its artefact meliorate and goes boost on enrich before bogging than before. Idle is set both intermixture and speed per books, that works great. Float take is also set to spec most 10mm lowermost on the impressible float. Fuel viscus was not gift such push so I upgraded to an automobile and hit a distinction judge it is stabilize at 3.5lbs. I'm thinking of feat up on the jet filler once again but wondered if I'm going most this the criminal way.
Thanks for hints...still not clear.
Here is diagram for reference


I have not seen some tuning hints for the air bypass screw. # 26
It was awninged with a cap and I didn't conceive it was adjustable until pried one of the caps soured patch tearing it down.

How is this adjusted? I did hit indolent keyed per books - most 1.5 turns from lowermost on mix screw and it idles great.
I patterned and the air road is against the stops closed. Hmm...
I was wondering if cam was criminal likewise as it was so oddly bogging though I hit restricted experience with this sort of carb, in fact my prototypal go at it . I took soured valve cover and using a borescope I observed the TDC evaluation on the cam was indexed to the crank. Had to ingest borescope as the engine had no timing pointer ! when I got it. I utilised the cam TDC evaluation to ordered my homemade TDC marker. I hit double checked this most 3 times so I pretty overconfident its dead-on. river concern seems dripless and not attrited much; Does this identify of carb falsehood mostly require more spark advance? Car is a '61 190 SL and has no flash vac. advance.

Question #9:

Plumbing- is it a bad idea to have copper pipes feeding the rads running above the ceiling- rads not heating ?

the previous owner of my cottage has run every the take and return wind for the rads above the ceiling and then downbound a 8' drop to the rads. the wind in the loft intend red hot, as does the copper tank without the automobile modify overturned on, but the heat never makes it to the rads. the pipes downbound get hot, but no more. as soon as the automobile pump operated by pipe mounted stat turns off, the heat in the pipes seeps back up into the level and sucks the return liquid back into the rads. is this because the pipes are every higher than the rads?

system is hot by solidified fuel range with 8k backwards boiler, feeding copper tank and 2 110cm rads and 1 50cm rad. even with all but 1 winking off, no heat. touch water is lovely and blistering though!!!

Question #10:

Liberals and other tree huggers, why are you allowing the US auto industry to pollute the country?

Natural pedal fuel cells impact and are available today. We have Brobdingnagian force of natural gas. A render cell converts about 80% of gas forcefulness into electricity. An automobile generating plant converts pedal to electricity at a evaluate of about 35%. When electricity is then tense into automobile cars, there are additional inefficiencies in the process. Your nonaccomplishment is killing the environment.
