Need help with a fuel leak

[AClayton]

Hey guys,

I have an 88' Chevy Crew-Cab that I transplanted a 92' 12V into. I have a fuel leak that appears to be the fuel filter....which I replaced. Thought that would fix my problem. I owned an 01' 24V previously so this 12V is a little different to me. The fuel appears to be leaking above the fuel filter but it looks to be all one piece of cast above it.


The truck runs very well as is but while its cold outside I am working through all the oil and fuel leaks that I have. Most of the other leaks and issues I can resolve but this has me stumped....can you guys offer any suggestions?

The fuel heater is above the filter by removing that and going to a Longer filter you should solve your Problem .

You can remove the fuel filter, use a big flat blade screwdriver or similar tool to unscrew the threaded spud & remove the heater assy. There is a square cut O-ring between the heater & manifold. If it is still a working unit you might want to re-install the heater for cold weather use.

Tuan, I'm going to assume you are asking an honest question, not just making a snide comment.
I guess the first issue is: Who/what is an expert?
Our trucks are all 20+ years old. A lot of the technicians in dealerships & shops were hardly born when these trucks were built. Most of the tech training now being offered is oriented at models much newer than ours.
At the same time, many of the folks posting on this and other forums have many years of personal experience working on these specific units.

Why not hire an "Expert"?
1.- A lot of personal satisfaction in doing the work yourself.
2.- A feeling of annoyance when people in service shops don't really want to listen to you. Tired of hearing-"It can't be done", "Parts are no longer available", etc.
3.- A certain feeling of camaraderie associating with the folks on forums such as this.
4- $$ -If you have a modicum of interest and ambition, and are willing to invest in (or have) the tools, you can save considerable money on maintenance & repair costs.

I spent 45 years as a professional mechanic. I'm now retired, but still have my tools, and a shop and continue to work on my own vehicles and those of family & friends. I attended countless technical seminars & classes, and often found that in conversation with other mechanics at those events, I learned as much as from the instructors.
This is exactly what happens on forums such as TDR!

I hope this answers your question.

That's the o-ring that started leaking on mine after ULSD came out. Got one from Cummins and fixed mine.
