Injectors - clean or replace / anyone have a set?

[Jim Wright]

Yes, pump is under the back seat.  Mark the two hoses and connectors with a paint pen to keep them straight.

My old pump was shot, that would have been the easiest way to drain down to the sludge.  I tried a siphon hose from Hatnor Freight that had a squeeze bulb going straight to the opening where the pump was,  didn't work well, kept getting clogged with sludge.  Garden hose and one of those spin pumps ended up doing what I needed before finally dropping the tank.

I ran two batches of hot water and mutation acid through, still left a bunch of sludge and residue I didn't want to deal with.

Aftermarket tanks may not mount the fuel pump the same way, I tried two different models from Spectra and wasn't happy with either.
