Fuel filter ?

[nighttrain2006]

I have a 86 m1009. I just changed the fuel filter housing. What is the round white part with a thin foam layer on it. It has two wires coming out of it and is almost flush with the housing. It is some kind of sensor? Mine Is broke and not sure of the parts name or function.

fuel pressure switch. it can not be replaced. That is the weak point in the system. They fail and suck air and cause all sorts of problems. There are new filters bases on ebay all the time for 50 bucks. You can also check Saturn Surplus --> Saturn Surplus on the Web! and other online suppliers.

on Ebay search CUCV.

Unit does not have the fuel pressure switch. Good company to deal with and shipping was fast.

fuel pressure switsh IS replaceable

Many years back on another list a big problem WAS diagnosed as caused by this piece going bad. There apparently were 3 versions of this switch, 2 were interchangeable. NATURALLY the M1028 I had, the unit was bad. Sent off for the part form a place I think was in CA. It came and "voila". I apparently had the ONLY version that was NOT interchangeable. NOW I have a box with 2 ( Figgering I am paying shipping, why not get two, right ? ) of the "other type, AND I went ahead and ordered a whole new fuel fitler base for the truck.
Lemme get to the "barn", find the box, ( it should be in the front seat of the M1028 ) see what I got and WHO I got it from and post it here. You might be able to use this stuff or try this guy.
Check and see if there are any numbers or anything that can identify precisely which unit ya got. NO use in me sending the stuff to you you cannot use either.

You got exactly what you should have,
and your better off without it!

I have a couple NOS bases with filter and no switch. $50 each.

My bases have a lightly different filter latch but should work fine, I'll post up a pic for reference.

 

[StreetbikeDepot]

Nope, mine have a larger filter.......I'm sure it would work though.

any difference between the bases on the civilian 6.2 trucks? got 3 of them sitting at the local junkyard.

Box is form "owens Export Service, inc." outa Chatsworth CA.

The fuel pressure sensor is USELESS.
Do not waste your money.
Either plug the housing port with a screw or
buy a housing without the again USELESS sensor.
The sensor is for Diagnostic equipment only.
It serves no purpose to fuel filtration or how your engine runs!
