I'm new to the forum and have read a lot of the posts, let me say that this is an extremely knowledgeable group, and you all seem to be quite passionate about the marque. I've a lot of respect for the thoroughness and professionalism of the authors I've read.
I read with interest your experience with a Holley 12-927 fuel pump as a replacement for the original Bosch unit, saving a lot of money in the process. I have a '70 280SE 6-cyl. that has been stored for about 12 years and I think the old pump is shot; it makes no noise but gets quite hot when the key is on so I suspect it's filled with nearly solidified gas. I'd like to replace the pump with the Holley but I'm wondering what sort of mounting issues I might run into e.g. bolt holes and such. Additionally does the Holley pump have all the correct ins and outs and are they relatively easy to match up to the old pump's?
For the record there are 2 possible pumps for my car, a larger unit and a smaller unit; mine is the smaller unit with the electrical connections closer to the base as opposed to the larger unit which has them higher up on the motor.
The car actually started and ran for about 10 mins the other day when I removed it from the garage where it was kept, then it stumbled, stalled and wouldn't restart. It's getting spark but no fuel which is why I first suspected the fuel pump. The pictures I saw here of an opened pump further my suspicion of it!
I'd appreciate any help any of you can render so I can go about returning the car to the road. I know there are other issues that'll arise but first I've got to get that engine running again.
Thank you all, in advance, for any help!
