omni sending unit

I need a sending unit for my 85 glh-t.

[Turboomni]

where you sending the unit too??

[4 l-bodies]

Need a little more info than that... Fuel? If so, one or two pump sending unit?

[thedon809]

It is under the fuel section . I would like the to do the 1 pump. I thought you could just put a walbro in it even if it was a 2 pump setup?

Sending units are completely different designs for early dual pump and later single pump. The 88-90 L-body TBI sending unit is the one you really need. After finding one of those, you need to replace the TBI pump with a higher pressure & volume Walbro or equivalent. It's not a complete bolt in, but can easily be made to work. I would imagine the dual pump assembly could be made to work, but it's not as easy as having the correct assembly to start with. Hey were there is a will, there is a way right? Another option would be to graft in a in-line pump. That is sort of what the external Bosch pump is anyway.
