Hello Roger, I have not checked, is the installation of the block studs on your 4crawler site.


Also, I have just converted an 86 cabrio to diesel (na). the car had a wiring problem as a gasser which confused the owner such that he gave the car to me. I can of course run the car on several work around power leads. does your site address wiring harness diagnostics at all and a possible alternative glow circuit add on beyond a toggle only source.


 I believe the in tank pump will be enough of a lift pump to run and drive though without an assist pump the engine does not get enough fuel to run correctly. 


My mechanic believes it should run wo an assit pump and something could be misfunctioning in the IP though before we do anything to the IP, because the engine has sat unused for several years, we decided to drive it, running some Ip treatment through it, expecting  that the performance will change.


thanks, r
