there is a site www.knfilters.com that make such equipment for v8 engines in particular K&N 59-3364 would probably fit
besides that go google and type in--- flame arrestors for air inlet--- and there is plenty of information on uses types etc
the idea is to have the ignition firing order right, the ignition timing correct (12 degrees btdc for chev)and the correct air/fuel mixture ratio and back firing will not occur unless you have a really rad**cal cam that is not correctly timed and the engine rpms are too low for the cam

After you remove the hub you then need to remove the inner gear and spring, this is done by removing the ring, look at the front edge of the gear, you will see ring, use small screw driver or pick to remove, it just sits in groove to hold hub gear and spring in place, when ring is removed then slide the rest of the parts to hub out, note some model will have a small star screw holding center gear in, remove screw and pull center gear out,

Next you will then see nut , these nuts are not too tight, you can use a chisel and hammer to break free if you do not have socket, after the first nut is removed you will then see a washer that has many small holes, that washer is a lock washer, it locks next washer in place , remove washer and you will be at last nut, take a look at the nut , the axle tube will have a slot, make sure there is not a slide pin going into nut to lock it, some models have a lock key, if you do then remove it with a magnet, you may need to wiggle nut to release pressure off the key, if you do not have the lock key then just remove the nut, take note the inner nut has a pin on the front face, when installing you will need to line it up to get lock washer on, here is a diagram to help you , good day and again these nuts are not tightened alot or bearing damage will occur just snug and chisel and hammer will loosen them. please let me know the outcome.9_2_2012_6_30_29_pm.gif

I bet you have a electric fuel pump?? If so, I'd be looking for a loose or broken wire/ bad connection first.
Next check the fuel filter, especially if it's not been changed.
You can also add some lucas (Not just Dry Gas) to the fuel tank with a mix of fresh gas - as it may be a piece of dirt lodging in the injector.
best regards

On some models of general motors starter shims are required to maintain
the recommended clearance between the starter and flywheel.
If not, then the starter will hang on the flywheel after motor is started and
damage it (The teeth are bottoming out when this occurs). They sell starter shims at
the auto parts store.
Hope this helps.

1986 GMC K1500 | Answered on Mar 21, 2011


not sure what you mean by ALL the bolts. there are only two bolts in the starter itself and they just retain the starter.

1986 GMC K1500 | Answered on Jan 17, 2011


Hi

yes this is dangerous, any heated wires so close to the fuel can be deadly. if they are melting then either the wrong fuse size has been used and this is overcharging the thinkness of the wires, thin wires require low amp fusees where as thicker wire higher fuses. the other issue is there is a possibility of overcharging or two wires contacting each other, this coaul destroy all the electric on the car and would be very costly to repair, I would be looking at wires contacting either each other or the car body "red" positives touching the metal work.

Get back to me with more info

Regards

Dan
