For next time, be sure to PM Morris4x4 here for your discount code. Or if you call, be sure to ask for Jessie, Hugo or John and tell them you are with Lee on CherokeeForum to receive the same.

Anyone besides XJwonders live up near Quadratec? If so, please let me know. Would be nice to have them as a vendor as well.

 

I actually ordered from quadratec since the price was so low and I had an account already, but I will remember that for next time I use Morris.

 

I live right by them and they know me well. Any issues, they will try to resolve. Someone only received 1 leaf spring in a kit. After the Postal Service had a claim filed against them, I went down, talked to them, they confirmed with the PS and Overnighted our member a new spring.

 

Opinions on whether or not a 23 year old fuel pump should be preemptively replaced? I'm getting ready to swap tanks, and I'll definitely be replacing the sock (filter) on the pick-up tube. I'm trying to decide if I should just replace the pump while I'm at it.

I'm leaning toward keeping the original one until it dies, unless it's in really bad shape when I pull it.

 

Having been left on the side of the road a few times due to bad fuel pumps over the years, I'd say replace it if you're going to be pulling the tank anyway. Been thinking about it on my own XJ since I have no idea how old the pump is.

 

It's my '93 Wrangler. I guess part of my question would be about the reputation of aftermarket sending unit/pump assemblies. I know to avoid Airtex, but I have several options regarding branding. For $250, I'm trying to decide if it would be preventative maintenance or if an aftermarket pump would be more likely to fail.

 

Could always buy one now and have it ready for when the old one goes? At least it would be right there instead of out of stock or have to order it or something.

 

Sorry, I didn't mean to derail the thread. I jusy like learning this kind of stuff and I know most of you in here know a lot more than me.

What do you mean by constant? Isn't exhaust pressure more like alternating waves of pressure? Especially since the 1rst and 6th cylinder have further to travel? Depending where the crack is I could see the pressure waves interacting in strange or unexpected ways. There's a ton of variables to account for too.

That would be great. Anyone with access to the DRB(or whatever it is) tool that could record some data? Wonder if someone like the guys from Roadkill that have the engine masters show would take on this question to prove or disprove it?

 

i can vouch that i have a pretty significant crack in my exhaust manifold and it runs 100% other than slightly ticking when i first starting it up in the morning, and it is that way since i first got it end of 2011.

 

Here's a picture of my crack before it was fixed. It actually caused a build up of black on the underside of my hood so for sure stuff was getting out. It ran noticeably better after the crack was fixed but I still had the problem with my MAP wiring shorting out intermittently, so I can't say if the crack itself would be enough to cause a noticeable change by itself without having other problems on top of it.

Thanks for your help guys!

 

Occasionally won't try turning over than randomly like yesterday worked perfectly fine all day *knock on wood*

 

Bosch pump only or keep the one that's there.

 

Thanks for your post.

With that vague of a question, no way to be sure. Could be a NSS. Try shifting to N then starting or wiggling the shifter.
