In bolt in the out bolt hole. Stupid question.

[shwak23]

Any adverse effects of using the in bolt in the out bolt hole on the injection pump? Just wondering.

Your dynamic timing will be all messed up, you might even not have any advance at all.

I have done it. Only because I had to.. as I had no OUT bolt when I went and bought a non running car and drove it home.. haha!

IT WAS HORRIBLE! No power at all, there was jack for internal pump pressure.. it was atrocious.

It pumps so much fuel that there is a huge vacuum after the filter,
 making large air bubbles appear in the fuel line.

Ah well thx for the answers. I put the in bolt in the out hole in an attempt to allow crud in the pump to flow out. Just wondering if that was maybe part of the reason it still runs rough.

That is actually a good idea. lol As can be seen it will still fire and run, and barely even drive. It will be down on advance, and power.. but shouldn't equate to more than a little higher EGT really because of the retarded timing.

But food for thought.. I drove a car 350kms straight with two IN bolts with no adverse affects to anything. Temps were still in check.

This pump I have was rusty as ***. The collar had to be unstuck using a screw driver as it wouldn't rev at all. Any way I soaked it in this EVAPORUST stuff. Took the lid off the pump and dumped this stuff in. Soaked it for 3 days. Refreshing the fluid around 3 times.

I bring this up because this stuff is amazing. It is biodegradable, safe on rubber, aluminum, etc, and it is water based.
This alternator fan had the same consistency of rust across it. I stuck half of it in this junk. 48 hours later...

Edit: I pulled this out of the liquid and took a picture zero scrubbing or wiping was done.


With nothing to lose I dumped it in the pump. Looks nearly perfect now. Put it on the car and it certainly already runs noticeably better. (With ZERO LEAKS.) *** diesel purge, *** atf. This *** is like a miracle. :-D

Anyway that's why I used the out bolt hole for the in bolt. Just incase any dissolved crud remained.

Interesting stuff...

EvapoRust is PFM (Pure ***ing Magic)! I used it once to clean out the scale in the turbo Y pipe for the 7.3 in my F-350. When the motor was out the Y pipe filled up with water and was full of nasty scale. I was afraid that if I did not get it ALL out a big chunk of scale would break loose and waste the turbo.

I plugged the 2 lower pipes with kids rubber balls and filled it up w/ EpapoRust and let it sit for a few days. It took every bit of rust and scale out and it looked like it had been glass beaded.

I put two out bolts in mine by mistake once. Then engine wouldn't run for more than a few seconds.

[audilvr]

mine had two in bolts and kept blowing the rubber lines off of the injectors.

It was trying to run on far less fuel flow capability! lol, Surprised it even fired.

Likely wasn't the issue, as that would cause no extra pressure in the return line then normal.

Hrmmmm... I rekon it might. Just guessing, but 10-20 psi at idle.

I drove four hours with two in bolts in my pump with no leakage to speak of, so he must have had a clogged return line for sure.

Hmmm well my rabbit still runs like garbage, it seems to idle and rev up but it gets all garbled as it revs up. The fuel in the injector return lines looks like chocolate milk no matter what I put through it for fuel. I believe the injectors will be the next thing to be dumped in the evaporust.
